1 00:00:01,770 --> 00:00:06,090 Okay. Could you start by saying your name and your affiliation, sir? 2 00:00:06,210 --> 00:00:15,120 I'm Derek Cook and a consultant in infectious disease and clinical microbiology in the John Ratcliffe Hospital, 3 00:00:15,870 --> 00:00:20,250 and then also a professor of microbiology in the Buffalo Department of Medicine. 4 00:00:21,090 --> 00:00:27,720 Thanks very much. And just very briefly, can you give me some kind of account of how you got to be where you are now? 5 00:00:28,950 --> 00:00:35,520 But the first step in the journey perhaps was growing up in rural South Africa and 6 00:00:35,880 --> 00:00:42,870 very rural South Africa and then made my way to medical school in Johannesburg. 7 00:00:43,230 --> 00:00:49,680 And then from there went through the London School of Tropical Medicine and Hygiene in London and then 8 00:00:49,680 --> 00:01:00,000 did my specialist training in the United States and then came to Oxford for the city four years. 9 00:01:02,910 --> 00:01:06,220 And what made you pick? Microbiology, as I said. 10 00:01:07,450 --> 00:01:12,440 Well, it is more. Not microbiology so much as medicine. 11 00:01:13,450 --> 00:01:16,690 I trained as a physician transmits infectious disease. 12 00:01:18,260 --> 00:01:25,999 Dr. And I've done a lot of general medicine and infectious disease work, but also trained in pathology, 13 00:01:26,000 --> 00:01:33,320 sort of became qualified as what one would call a jobbing microbe ologist. 14 00:01:33,980 --> 00:01:45,380 But preceding that, I've done a lot of research in the United States on microbial behaviour and that was. 15 00:01:46,580 --> 00:01:53,879 Sort of. A natural a starting point to do what we refer to as clinical microbiology. 16 00:01:53,880 --> 00:01:58,500 And the differentiation between them at many levels is not great to enough. 17 00:01:58,500 --> 00:02:05,760 Two other differences quite substantial living across the practise of medicine but infectious disease, 18 00:02:05,760 --> 00:02:10,020 but also having an understanding of the scientific basis of the microbes that cause disease. 19 00:02:11,460 --> 00:02:16,560 So summarising it, I mean, the question I've written down is I'm asking everybody this. 20 00:02:16,740 --> 00:02:22,080 If you had to define a single big question that gets you out of bed in the morning, what would it be? 21 00:02:22,590 --> 00:02:26,670 But I could rephrase that. I'm not sure if it's the same question or not as what appeals to you about bugs. 22 00:02:33,380 --> 00:02:40,550 That's sort of an interesting question because it's it's really solving problems that gets me out of bed in 23 00:02:40,550 --> 00:02:47,440 the morning rather than and tax bucks represents one end of a spectrum of troublesome problems that you can, 24 00:02:47,820 --> 00:02:58,830 can, can. Entertain yourself with a little and excite yourself with other levels and the diseases that cause a 25 00:02:58,830 --> 00:03:04,890 fascinating in the way that they interact with their hosts and affect hosts at an individual level, 26 00:03:04,900 --> 00:03:06,270 at a population level. 27 00:03:07,020 --> 00:03:17,940 So it's really probably the interface between medicine and biology and all of that through fields that's appealing and interesting. 28 00:03:19,170 --> 00:03:22,229 I like caring for patients. I like solving problems in the lab. 29 00:03:22,230 --> 00:03:27,900 I like writing papers. I'm lucky to do a lot of those. 30 00:03:30,180 --> 00:03:39,060 So let's move on to the pandemic. Can you remember how you first heard that there was a pandemic in the offing? 31 00:03:41,540 --> 00:03:46,680 Well, I mean, it was just in the media and it was a. A. 32 00:03:49,350 --> 00:03:56,760 A reference to it in the media, which was enormously similar to the first source outbreak. 33 00:03:56,910 --> 00:04:03,500 It is completely reminiscent of that giant January or was out before it was December. 34 00:04:03,510 --> 00:04:13,820 It was December 2019 and 19 December who had and I don't know whether 12 or 14 years before that. 35 00:04:15,310 --> 00:04:29,860 The settlers outbreak that started in the southern provinces of China and then became prevalent in Hong Kong and didn't become a pandemic. 36 00:04:31,380 --> 00:04:34,810 Well, this one did. But they're very similar at the beginning. 37 00:04:35,080 --> 00:04:45,180 Yeah. And did you how did you sort of slow realisation that this was something that was likely to affect us? 38 00:04:45,180 --> 00:04:51,960 Or did you initially think, Oh, that's interesting, there's another cell is happening in the forest and not expect it to? 39 00:04:53,280 --> 00:04:56,300 I didn't have very strong expectations one way or another. 40 00:04:56,310 --> 00:05:02,070 I mean, so as the first epidemic petered out, the Zika. 41 00:05:03,420 --> 00:05:07,479 If it was huge in the media. 42 00:05:07,480 --> 00:05:14,610 But for editing that was in Brazil, it's well, it was one of the particular first. 43 00:05:14,610 --> 00:05:18,760 So I was in Brazil for it preceded it, I think it was evident before. 44 00:05:18,910 --> 00:05:24,390 So I grew up with Zika in Africa. So big deal and. 45 00:05:25,900 --> 00:05:41,350 And then there were similar limited outbreaks of of of other viral illnesses, such as sort of curvy in in the Middle East. 46 00:05:41,410 --> 00:05:44,890 And there's obviously a particular outbreak in South Korea. 47 00:05:45,400 --> 00:05:49,900 So you wouldn't was aware of this. It was only really. 48 00:05:53,190 --> 00:06:01,620 January, February. Did you realise that there were going to be problems in an office of the W.H.O. in. 49 00:06:03,810 --> 00:06:11,280 Like January. And it was just becoming apparent that Italy, the north of Italy, was having a particular problem. 50 00:06:12,270 --> 00:06:19,140 And then it pretty rapidly became clear that this was going to spread around the world. 51 00:06:22,470 --> 00:06:32,230 I was of first. I feel particularly alarmed about it because it was going to do from pretty even temper tantrums. 52 00:06:33,760 --> 00:06:39,010 I looked at it with equanimity rather than a huge mess. 53 00:06:39,470 --> 00:06:45,430 Mm hmm. But did you think this is going to change the way I work or what I work on? 54 00:06:46,600 --> 00:06:53,020 No, it isn't going to change the way that that plan would work at that stage. 55 00:06:53,920 --> 00:07:03,850 But it soon became clear that it was going to be a need for a huge effort and a massive response. 56 00:07:06,630 --> 00:07:11,820 That's what we've vaguely anticipated, what would be involved in that? 57 00:07:12,060 --> 00:07:22,410 But in other parts of what used to be called Zulu land in South Africa, what about other cholera outbreak outbreaks? 58 00:07:23,340 --> 00:07:29,010 I've directed a major part of the Public Health England where we were thinking about these sorts of things. 59 00:07:32,060 --> 00:07:39,200 I'm not taken with a long speech. I'm not trying to alarm the children. 60 00:07:39,300 --> 00:07:49,760 I mean. But. Yes, yes, yes. I was matter of fact about it. If if it grew into something that was huge, one would deal with it and become involved. 61 00:07:50,750 --> 00:07:55,380 So just this is just sort of by the way, that's always been the case. It wasn't just because this was about you. 62 00:07:55,450 --> 00:08:00,440 Yeah. Yeah. So just to my background, to what we can talk about later. 63 00:08:00,830 --> 00:08:12,320 Can you just outline briefly the natural history of the the epidemic as it's evolved from from December 2019 till till now, 64 00:08:12,650 --> 00:08:17,960 in terms of where different variants appeared around the world and how they've affected case numbers. 65 00:08:18,110 --> 00:08:34,850 So yeah, there's some aspects of it that were pretty predictable in the sense that if you have a pandemic, it's just around the world. 66 00:08:35,480 --> 00:08:41,680 You knew that it would go away. So that was very clear. 67 00:08:41,680 --> 00:08:49,670 It occurred ways that because of the immunity arising and then very people don't really know why waves happen. 68 00:08:50,570 --> 00:08:58,170 Flu does. This is the biology behind this sort of not that clear. 69 00:08:59,100 --> 00:09:03,710 I mean, the 1918 flu epidemic were. 70 00:09:05,000 --> 00:09:11,780 Please. It's interesting. Must be a bit of you being a part of the way people behave. 71 00:09:12,800 --> 00:09:17,000 But this season. A lot of variables. 72 00:09:17,690 --> 00:09:24,410 So that was all going to be expected in my mind. 73 00:09:25,250 --> 00:09:32,660 What wasn't really prepared for is how the properties of the virus would change. 74 00:09:33,900 --> 00:09:44,580 And they have changed to list some characteristics. It is, in retrospect, easy to understand so that it would be completely intuitive. 75 00:09:45,600 --> 00:09:49,400 But you didn't expect it was going to happen. 76 00:09:49,410 --> 00:10:00,270 And those that those changes had to do with how to adapt it to the human which wasn't expected or other animals, as it did to me. 77 00:10:02,340 --> 00:10:05,910 But it would become hugely more transmissible. 78 00:10:07,110 --> 00:10:17,249 And then a lot of the hysteria increase of pathogens of the species is that it could be more 79 00:10:17,250 --> 00:10:25,650 variant at the beginning and over time adapt to the host and become a lot less virulent. 80 00:10:26,430 --> 00:10:34,290 Not clear that's happened yet, but one of the reasons for that immune escape is very well recognised. 81 00:10:35,620 --> 00:10:43,350 So that wasn't really a surprise. The stick changes and transmission was a bit of a surprise. 82 00:10:43,590 --> 00:10:48,210 This is with the emergence of new variants. It's only son. 83 00:10:49,470 --> 00:10:53,070 So you mean the same variant can increase its transmissibility? 84 00:10:55,510 --> 00:11:01,360 Well, what you're hitting on is something that got to do is lazy terminology. 85 00:11:03,520 --> 00:11:10,060 Variances in some settings are very, very specific terms. 86 00:11:10,120 --> 00:11:15,040 You get a single alteration in the genetic makeup. 87 00:11:15,520 --> 00:11:22,600 But in terms of the way one has used it for the pandemic is. 88 00:11:24,180 --> 00:11:30,780 Actually a specific word for it would be a lineage. 89 00:11:31,840 --> 00:11:40,730 It's quite often has a number of mutations in it. And then in respect of transmissibility, it's. 90 00:11:41,900 --> 00:11:48,170 It's a causative mutation that occurs, occurs and that can be on lots of different individuals. 91 00:11:49,430 --> 00:11:54,590 And therefore variant is a funny way of describing it. 92 00:11:54,800 --> 00:12:00,620 You might be aware of that, but it's it's confusing to to a lot of people. 93 00:12:00,620 --> 00:12:10,370 And the more that the virus combines with itself or with it, you get kids get convergent evolution. 94 00:12:10,370 --> 00:12:16,110 That's where the same mutation occurs and very different. Settings are linked. 95 00:12:17,140 --> 00:12:33,370 Settings of the virus because of selection, you rapidly realised that the business was down to a few specific mutations and that's been surprising. 96 00:12:33,520 --> 00:12:42,430 The extent to which the transmissibility of the virus has been changed by some specific mutations or might be a combination of mutations, may vary. 97 00:12:42,940 --> 00:12:45,379 Researchers, not myself, 98 00:12:45,380 --> 00:12:52,840 but researchers are very interested in how that might be additive with synergistic effects between combinations of annotations, 99 00:12:52,840 --> 00:13:01,930 but it's certainly mostly down to single mutations, resulting in these quite profound changes in the behaviour of virus. 100 00:13:03,470 --> 00:13:17,480 And some of them are thought to go hand in hand with altering it to the ability of the virus to escape immune protection of the host. 101 00:13:19,580 --> 00:13:22,640 Which was expected. I mean, that is quite common. 102 00:13:24,140 --> 00:13:27,410 So one thing I should have asked you earlier is I've I've got a question here. 103 00:13:27,440 --> 00:13:30,200 What methods do you use to explore the question? 104 00:13:30,220 --> 00:13:37,940 And I know you've been involved in a project, you know, if it's a project, an umbrella thing called modernising medical microbiology. 105 00:13:38,760 --> 00:13:43,700 So can you just explain for the uninitiated what that involves? 106 00:13:46,720 --> 00:13:56,030 So that that collection of people that have come together in this modernising medical microbiology arose from a large quantity. 107 00:13:56,030 --> 00:14:01,690 We succeeded in getting. And it's it's it's grown organically. 108 00:14:02,140 --> 00:14:05,320 Independent research is working very closely together. 109 00:14:06,070 --> 00:14:09,160 And that's something a number of years ago. 110 00:14:09,430 --> 00:14:12,459 In 2008. Yes. Yes. 111 00:14:12,460 --> 00:14:21,400 That's about the. And. The ambition there was to. 112 00:14:23,060 --> 00:14:28,370 Make use of new technology. So we're going to bear on. 113 00:14:30,570 --> 00:14:38,430 Science in general, but in particular on microbial science and human infectious disease science. 114 00:14:38,730 --> 00:14:44,640 And you could look at them holistically rather than as discrete parts of it. 115 00:14:45,330 --> 00:14:50,040 And the technologies that are driving that. 116 00:14:51,720 --> 00:15:01,040 Digital computational. Technology is quite obviously and very closely linked to that to the. 117 00:15:02,240 --> 00:15:09,800 Tools enable you to recover the genetic code and in its entirety. 118 00:15:11,060 --> 00:15:16,730 And the synthesis of those two made you able to assemble. 119 00:15:18,420 --> 00:15:34,860 The code that's generated in little bits to form the whole chromosome with the genetic structure and then to mine that reflation again. 120 00:15:36,400 --> 00:15:44,330 This. It's highly dependent on really advanced computational processes. 121 00:15:44,330 --> 00:15:49,310 It's really fancy software, very high performance computers. 122 00:15:50,480 --> 00:15:56,140 And then if you have that layer of information, how can you link it? 123 00:15:56,720 --> 00:16:04,070 You know, if you're doing medical science to people and to do things like tracking infection in hospitals. 124 00:16:04,680 --> 00:16:14,500 Yes. You know, understanding all manner of things, what the risk factors that account for people developing disease. 125 00:16:14,580 --> 00:16:21,260 You could do all of the same things with human genetic code and it was more microbial in. 126 00:16:21,260 --> 00:16:25,819 But there's quite a strong piece that's got to do with human genomics, 127 00:16:25,820 --> 00:16:32,690 but a huge part that's got to do with large datasets about humans and health care systems. 128 00:16:34,040 --> 00:16:44,839 What do people with a certain infection get? Severe illness and some very deadly illness, and how does that distribute across populations? 129 00:16:44,840 --> 00:16:47,990 And to do those very large. 130 00:16:49,790 --> 00:16:54,650 Analysis across large numbers of people and the microbes that they've got. 131 00:16:55,490 --> 00:16:58,580 You could argue address by having confidence computing again. 132 00:16:58,670 --> 00:17:02,760 I mean, it's very robust information. You're going to speak to Sarah Walker. 133 00:17:02,780 --> 00:17:08,060 She's become absolutely key in that sort of work. 134 00:17:09,320 --> 00:17:17,209 And and that was really the background thinking about modernising medical microbiology schemas. 135 00:17:17,210 --> 00:17:24,140 How can you take these new technologies and as a result of studies, generate new information, 136 00:17:24,560 --> 00:17:29,960 identify better ways of doing things that include better diagnostics? 137 00:17:30,710 --> 00:17:37,130 And, you know, how can you identify ways of of of. 138 00:17:40,070 --> 00:17:48,080 Recognising the best ways of preventing the spread of infection or even recognising when you have spread of infection, you can have interventions. 139 00:17:49,250 --> 00:17:58,280 I think we have had a marvellous time, you know, again, holistically looking at the subject. 140 00:17:59,240 --> 00:18:03,830 Can you give me some examples of some of the kinds of infections that you were interested in before COVID came along? 141 00:18:05,120 --> 00:18:21,260 Well, a couple that have been highly illuminating if you take a disease caused by Clostridium difficile. 142 00:18:22,980 --> 00:18:26,389 We had a. Amongst us. 143 00:18:26,390 --> 00:18:28,390 We got a sense of humour, decency. 144 00:18:30,140 --> 00:18:53,850 There was a great political imperative, almost interest, in ascribing the presence of these jobs as the disease to dirty hospitals. 145 00:18:53,870 --> 00:18:57,140 I don't know if you can remember it in the press a lot. 146 00:18:57,740 --> 00:19:11,819 We were sort of. Kind of unimpressed with reset and set about very deliberately to investigate the organism with that 147 00:19:11,820 --> 00:19:20,670 particular question in mind and did a huge amount of work very carefully and in a systematic way, 148 00:19:20,670 --> 00:19:27,120 collecting cases with the germ and with information about them and the germs themselves, 149 00:19:27,120 --> 00:19:39,269 and were able to recover the genetic code by sequencing the microorganisms and then did combined epidemiological and microbial investigations. 150 00:19:39,270 --> 00:19:50,810 The. The outcome of which was that the evidence for the hospital being dirty and the source of the infection was by mute. 151 00:19:52,250 --> 00:20:01,490 And it was much more of a matter of these organisms increasing into the hospital environment, probably through other people. 152 00:20:02,930 --> 00:20:06,260 And so people could carry them around and be perfectly well. 153 00:20:06,750 --> 00:20:07,980 I mean definitely, yeah. 154 00:20:08,000 --> 00:20:18,740 It's like 98, 99% of the germs life is in people who don't even know they've got it, never had a problem with it, but maybe even 99.5%. 155 00:20:21,710 --> 00:20:29,330 Particularly children. Write another story. And that was sort of entertaining not to be opposed. 156 00:20:29,330 --> 00:20:37,350 The idea of keeping the hospitals, but the idea that the germ represented a market for a dirty hospital per se. 157 00:20:37,840 --> 00:20:41,080 It was a marker for a lot more than that huge amount. 158 00:20:41,120 --> 00:20:52,550 Not all of it. Entirely teasing, and then we were able to demonstrate pretty convincingly. 159 00:20:55,290 --> 00:21:01,799 Better than pretty convincingly that the whole so-called epidemic had to do with the way 160 00:21:01,800 --> 00:21:08,190 that germ had become resistant to an antibiotic called ciprofloxacin quinolone antibiotics. 161 00:21:08,760 --> 00:21:21,959 And what you had is the linkage of Clostridium difficile that acquired this causative gene that made it resistant to quinolones. 162 00:21:21,960 --> 00:21:27,270 And then it's very rapidly. True selection. 163 00:21:28,180 --> 00:21:33,460 But black sites could be two reasons why. 164 00:21:34,570 --> 00:21:49,060 This is the selection going on in the background. And once Quinolone usage went down some 50% in the community amongst general practitioners. 165 00:21:50,150 --> 00:21:58,900 These lineages reduced in number and disappeared and the epidemic disappeared with it. 166 00:21:59,260 --> 00:22:06,430 So it had nothing to do with the hospitals and had everything to do with the use of these quinolone antibiotics. 167 00:22:07,240 --> 00:22:15,400 So that was sort of entertaining and a counter to various political slogans. 168 00:22:15,940 --> 00:22:28,900 We enjoyed that some loved and that you could never have discovered that without extremely sophisticated computing and DNA sequencing and systematic, 169 00:22:29,140 --> 00:22:34,120 careful accumulation of information about the patients, 170 00:22:34,120 --> 00:22:38,270 which we got from linking clinical records systems in the hospital and getting all 171 00:22:38,290 --> 00:22:44,010 the the necessary information governance arrangements organised by the hospitals, 172 00:22:44,020 --> 00:22:54,670 a huge effort. All those permissions to do it in a very diligent and safe way in terms of I think we've done some of the work with TB. 173 00:23:07,980 --> 00:23:12,780 With TB. It's got lots of dimensions to it, 174 00:23:12,780 --> 00:23:27,930 but one of the most pleasing is that we can take the genetic code and mine the genetic code and find signatures of resistance in the genetic code. 175 00:23:29,430 --> 00:23:44,610 Get closer to mutations. There's a theme here and they they can be one amongst 4 million, 400,000 other nucleotides. 176 00:23:44,910 --> 00:23:50,670 And that one change turns the organism from susceptible to resistant. 177 00:23:51,210 --> 00:24:03,750 If you can very reliably identify those changes and determine purely genomically whether the organism is going to be resistant to. 178 00:24:05,840 --> 00:24:17,530 Activity, licence, drug or not, and make decisions about whether to use it without doing the tedious job and the big faff of growing 179 00:24:17,530 --> 00:24:23,530 its growing in the presence of the drug and figuring out if it grows from what started when we just 180 00:24:23,620 --> 00:24:29,979 completed a huge global project across 27 countries around the world doing this in scale and then just 181 00:24:29,980 --> 00:24:40,420 publishing a large number of patent papers that enable one to make those deterministic predictions from. 182 00:24:42,440 --> 00:24:48,950 Computationally analysing the virtual codes and singling out which drugs that particular 183 00:24:48,950 --> 00:24:54,020 strain would be resistant to and whether they are susceptible to those drugs. 184 00:24:54,060 --> 00:24:57,590 And you can make that differentiation with a very high degree of accuracy. 185 00:24:58,840 --> 00:25:02,830 And it's transmogrified how you practise. 186 00:25:04,250 --> 00:25:09,840 You know. Tbe Manager management. 187 00:25:10,610 --> 00:25:14,300 And it was very heavily used. 188 00:25:15,540 --> 00:25:21,450 In assisting the W.H.O. created a catalogue, as they call it, 189 00:25:21,690 --> 00:25:27,120 which is just a repository of the information about each one of those changes in the 190 00:25:27,120 --> 00:25:33,840 genetic code so that people could develop tests for this various configurations and. 191 00:25:35,150 --> 00:25:43,190 We really did most of the work towards creating this W.H.O. dust catalogue. 192 00:25:43,610 --> 00:25:51,620 You think it could be a lot better when you're publishing all the papers too, to understand and target you would do that. 193 00:25:51,910 --> 00:25:55,280 So again, that is the computation. 194 00:25:55,730 --> 00:26:01,610 Huge, systematically collected samples around the world, brought together and analysed. 195 00:26:01,620 --> 00:26:12,670 And it's not just medicine scientists of all different sorts as people from all around the world that want to effectively work together. 196 00:26:12,680 --> 00:26:22,200 We had fantastic success working with China, India, the United States, and then many countries in Africa, Asia. 197 00:26:22,820 --> 00:26:35,750 South America. So just to drag you back to Kobe, you had this tremendous set of tools for interrogating pathogens, infectious disease pathogens. 198 00:26:36,440 --> 00:26:49,880 What point did you decide that you were going to turn some of that power on this new, new infection and help us do it with different drugs? 199 00:26:50,270 --> 00:27:00,190 Well, how did it just what how did it happen? Well, as Sara and I said, you know, this is going to be a ridiculous feeding frenzy. 200 00:27:00,260 --> 00:27:04,880 But to do research, we'll just work to support the general effort. 201 00:27:05,060 --> 00:27:11,010 Right. And then about. February. 202 00:27:11,020 --> 00:27:16,590 March. John Bell contacted me. 203 00:27:16,620 --> 00:27:22,490 He said, you know, in government we've got a huge problem because we can't find people to. 204 00:27:23,830 --> 00:27:29,530 Do what would be considered banal, menial, almost menial jobs. 205 00:27:30,400 --> 00:27:33,490 Trying to stand up huge scale testing in the country. 206 00:27:34,600 --> 00:27:41,410 And we don't even know whether any of the techniques involved in testing just how you swap or troops you carry stuff in, 207 00:27:41,890 --> 00:27:51,850 how you process through through PCR machines, whether any of them meet the standards means we can roll this out in the country. 208 00:27:53,680 --> 00:28:07,569 And then they were starting to market a whole lot of kids to see whether you picking your finger had antibodies to to the virus indicating 209 00:28:07,570 --> 00:28:19,360 that you you had some element of immunity and there were all manner of people trying to sell government's complete rubbish and said, 210 00:28:19,540 --> 00:28:22,750 we know this. Can you do stuff to help us set it all up? 211 00:28:23,100 --> 00:28:29,319 We will we will assist in the effort. 212 00:28:29,320 --> 00:28:36,410 So we set up a programme of work between here and at Porton Down and our new people from Porton Down. 213 00:28:36,410 --> 00:28:43,180 So to Public Health, England, that started screen swaps, 214 00:28:43,180 --> 00:28:50,750 just standard swaps to make sure that they were safe to use and it would not affect the testing values. 215 00:28:50,830 --> 00:28:57,670 And we did talk about 500 swaps, but just the actual swap, just to stick with the bits of cotton wool to make sure it works. 216 00:28:57,670 --> 00:29:03,040 Right. My goodness, we didn't get hundreds because we think they're going to be manufactured. 217 00:29:03,040 --> 00:29:09,810 That would be flown into the country that were all the supply problems and you didn't know if you were buying rubbish or things that were. 218 00:29:10,300 --> 00:29:17,260 So we set this up on a massive scale so they could buy with the understanding or knowledge that 219 00:29:17,440 --> 00:29:24,990 these standards that you would say of safe to use and would not alter the performance of tests. 220 00:29:25,150 --> 00:29:28,090 That's what it was, but no mindless sort of work. 221 00:29:28,160 --> 00:29:36,370 We set up systems to do it on a huge scale and then we did the same to Immunity and I managed to call up friends around the 222 00:29:36,370 --> 00:29:45,609 country because people had been infected with and then we had these banks of Sierra that we could then test and rollout tests. 223 00:29:45,610 --> 00:29:49,600 We developed a huge allies of test here, just expanding the likes of test. 224 00:29:50,320 --> 00:29:53,500 So it's a particular way that you measure antibodies. 225 00:29:54,520 --> 00:29:58,180 So this was invented many years ago. 226 00:29:59,110 --> 00:30:02,230 So antibody target, something which you can say is an antigen. 227 00:30:02,530 --> 00:30:16,030 If you mobilise antigen somewhere, you can bring the antibody solution close to the localised antigen, targeted binds to the target. 228 00:30:16,540 --> 00:30:23,529 And then you have ways of detecting the presence of the antibody on the antigen target because it binds very tightly. 229 00:30:23,530 --> 00:30:33,759 If you wash stuff away, you're left with the antibodies and you can get signals for its presence and you can put this into a whole range of settings. 230 00:30:33,760 --> 00:30:41,440 And we did this through Clayton and I think you place it through a pretty to trace you've seen them but how does that 231 00:30:41,440 --> 00:30:50,590 differ from the commercial antibody tests of which I've done one because of the UK Biobank them to finger prick ones. 232 00:30:51,160 --> 00:30:57,910 It's a different way of presenting the antigen and operating the test. 233 00:30:58,090 --> 00:31:03,790 They're all the same biochemical reaction behind it, but different representations of it. 234 00:31:04,210 --> 00:31:20,970 So we've got the national testing for the COVID 19 epidemiological survey is run by the Office of National Statistics. 235 00:31:20,980 --> 00:31:27,550 I can take you ensure that we run through 5000 to 6000 samples today just around the corner here 236 00:31:28,150 --> 00:31:36,700 and test them on machines for the presence of antibodies to different parts of the virus spike 237 00:31:36,700 --> 00:31:46,179 apart from the protein part and the beginning of the journey to doing that started with being 238 00:31:46,180 --> 00:31:52,180 able to do the testing to demonstrate these various kinds of people have made we're ready, 239 00:31:52,180 --> 00:32:03,690 almost uniformly hopeless. And on the side we started to make one that would perform to hugely improve support you with performance drugs. 240 00:32:04,570 --> 00:32:18,330 And now we've got that now fully established as a test with all the regulatory approvals that run 150,000 tests a month, and it's absolutely not that. 241 00:32:18,380 --> 00:32:21,460 So we're telling you because that's had to be used in a lab setting. 242 00:32:21,940 --> 00:32:26,900 Can that. Yes. Yes, yes, yes, yes. 243 00:32:27,050 --> 00:32:36,120 If you get 6000 samples coming to the hospital for this is more than the entire pathology service in this hospital runs a day. 244 00:32:36,450 --> 00:32:40,830 Right. So you've got this. I'll show it to you. It's stuck. 245 00:32:41,010 --> 00:32:42,270 My gosh. How did that happen? 246 00:32:43,950 --> 00:32:55,589 And so and that work was going on very closely to Jordan, working with the government, trying to stamp things up and end it. 247 00:32:55,590 --> 00:32:58,649 But at some point in this process, when it was quite early on, wasn't it? 248 00:32:58,650 --> 00:33:03,240 It was early March when the government suddenly said, we're going to have to stop testing. 249 00:33:04,290 --> 00:33:09,490 So we were doing the PCR testing. That was accuracy. 250 00:33:10,710 --> 00:33:22,950 It's actually that's quite interesting. That was the huge. Sort of realisation that Public Health England wasn't able to deliver the services that 251 00:33:22,950 --> 00:33:31,560 would enable testing and many of the the the components of the national response. 252 00:33:32,740 --> 00:33:37,000 In fact, I think the organisation went through a minor collapse. 253 00:33:37,150 --> 00:33:46,270 That's how we got involved. They couldn't process these samples within their management structure because we put them down, 254 00:33:46,330 --> 00:33:52,360 because we use the people that we set up a system for doing it with very able people. 255 00:33:52,360 --> 00:33:58,090 But the formal structures that they had, the response malfunctioned early on. 256 00:33:58,660 --> 00:34:02,440 And one of the aspects of that was working with the NHS. 257 00:34:03,040 --> 00:34:13,720 They weren't able to run our tests and that really was a huge interest in setting up these lighthouse labs and mega labs. 258 00:34:13,840 --> 00:34:15,700 The decision was highly controversial. 259 00:34:15,710 --> 00:34:23,680 It wasn't a very straightforward thing and there was a lot of rancour around it, like a local hospital was very upset about it, hugely upset about it. 260 00:34:24,670 --> 00:34:34,570 But to do it on scale, you had to deliver the reagents and the tools to do it, swabs and all the rest. 261 00:34:35,140 --> 00:34:41,020 And you had to stand up to the labs themselves, which we didn't really get directly involved in, 262 00:34:41,020 --> 00:34:46,389 although we put a huge effort into making sure that the workflows functioned very well, 263 00:34:46,390 --> 00:34:50,170 the tabulate tested those and put them on to the right footing. 264 00:34:51,040 --> 00:34:55,150 So and I got to know some of those people very well. 265 00:34:57,120 --> 00:35:02,640 As well as setting up things in the hospital because we have a responsibility and a job to do that locally. 266 00:35:02,910 --> 00:35:07,830 So this wasn't really research. No, but it was a COVID response. 267 00:35:07,830 --> 00:35:16,020 So just so it counts case. And so all those wonderful things we were doing and then we have lots of people around. 268 00:35:16,020 --> 00:35:27,240 They were enthusiastic. We came to work every day. We worked, you know, a minimum of ten, 12, 14 hours every day, non-stop, all three weekends. 269 00:35:27,540 --> 00:35:33,779 And you say it wasn't research, but there were papers published. I mean, I've seen the paper in which you published this. 270 00:35:33,780 --> 00:35:37,590 How, how rubbish the commercial antibody test. 271 00:35:38,090 --> 00:35:48,030 We published more stuff this year. So we, we drew together all the young researchers we have all the old ones as well, 272 00:35:48,120 --> 00:35:54,780 everybody and we both teams, we've worked unbelievably and unrelentingly through this whole process. 273 00:35:55,650 --> 00:36:04,280 And then gradually as we and then Sara got recruited to go and run or in this study as the chief investigator. 274 00:36:05,130 --> 00:36:08,860 In fact, she sits next to her. So she she lives and breathes. 275 00:36:11,220 --> 00:36:16,590 And then we started to build very substantial research, 276 00:36:16,590 --> 00:36:22,560 focussed around along the lines of we spoke about getting back to the genomic kind of research. 277 00:36:23,460 --> 00:36:35,460 We are working on that very intensively as a consequence of a charitable philanthropic donation from Article ten years worth of their cloud resources. 278 00:36:38,410 --> 00:36:54,320 Unlimited to support. Genome sequence data assembly variant coding mutations emit another analysis storage around the world. 279 00:36:54,500 --> 00:37:01,880 So this is this builds on your scalable pathogen pipeline platform. 280 00:37:02,960 --> 00:37:09,500 And this is not all that's about that. Well, that was a very lovely little innovation that was made. 281 00:37:11,790 --> 00:37:13,470 Out of tbe work we did. 282 00:37:13,800 --> 00:37:33,180 We took the first very poorly designed, very poorly coded software for taking the sequences of TB, assembling them and identifying other. 283 00:37:34,600 --> 00:37:39,610 Samples of TB the group very closely related and we could. 284 00:37:41,350 --> 00:37:50,710 Quantify that relationship so that we know that that been recently acquired from the person. 285 00:37:53,200 --> 00:38:01,420 For one of two people who had it, if you reduced it down to two, was a cluster that would require that somehow from each other. 286 00:38:02,170 --> 00:38:10,720 And that became this unit one known for identifying outbreaks of TB and is known nationally and how you trace those people. 287 00:38:12,610 --> 00:38:21,040 Test and trace and then how you could predict resistance and all of that work. 288 00:38:21,040 --> 00:38:30,990 We were able to say just from the gene. Code analysis that you've got to suspect that one can use any one of the drugs safe. 289 00:38:31,410 --> 00:38:35,440 You know, you've got a resistant one. Think about that a bit more, which we can do. 290 00:38:35,440 --> 00:38:41,710 And that's a national service. We developed that it became very clear to us that we had to. 291 00:38:44,170 --> 00:38:50,499 Change the paradigm and that actually we wouldn't be able to establish with 292 00:38:50,500 --> 00:38:55,810 computational resources locally and many data centres or computer clusters, 293 00:38:56,170 --> 00:39:07,159 we'd have to put the software to the cloud because it became very clear that we couldn't design and create software that reached industry standards. 294 00:39:07,160 --> 00:39:13,899 So we started working very hard on trying to understand what you could do better and hoped that we 295 00:39:13,900 --> 00:39:24,070 would eventually have a partner with some tech organisations that would aid and assist in doing this, 296 00:39:24,070 --> 00:39:29,920 as you would say properly. And that has happened as a result of the pandemic. 297 00:39:30,670 --> 00:39:36,010 And it was recognised that the code that we had written that would provide a 298 00:39:36,010 --> 00:39:41,800 platform for running the tools could be run in any one of the big global clouds. 299 00:39:43,920 --> 00:39:52,850 And that was called this piece. I don't know what it is, but it's a scalable pathogen pipeline platform. 300 00:39:55,170 --> 00:40:00,450 And that was it. That's what the West is. You know, it's in the name but yet did. 301 00:40:01,680 --> 00:40:09,780 And that was recognised as a as a. That's quite an innovative development. 302 00:40:10,200 --> 00:40:14,460 The sad thing is that as innovative as it was, 303 00:40:14,550 --> 00:40:23,400 it's not scalable because there's so many other attributes that go into designing something like that and coding it that make it scalable, 304 00:40:23,400 --> 00:40:34,020 but which you mean you can put it on these cloud technologies and you can run in parallel, not just ten, 305 00:40:34,020 --> 00:40:41,520 not just 100, but thousands and tens of thousands of these jobs simultaneously and bring them together. 306 00:40:42,030 --> 00:40:49,320 So that requires coding and platform, that enables that. 307 00:40:49,830 --> 00:40:53,580 And although this intended to do it, it didn't do it very efficiently. 308 00:40:54,270 --> 00:40:58,110 It's interesting to see that of the experienced Oracle. 309 00:40:58,110 --> 00:41:01,799 Now that we are learning that you're going to have to redesign a lot of that. 310 00:41:01,800 --> 00:41:07,390 You have to refactor it. And you have to. Restructure a great deal. 311 00:41:07,390 --> 00:41:10,660 And so we had the insights before the pandemic. 312 00:41:10,660 --> 00:41:19,900 The pandemic came along. We can now do the thing that we think to do much better, massively, massively that we would have otherwise done. 313 00:41:20,230 --> 00:41:30,880 So what? What are the questions that you can answer using that that particular technology in relation to the pandemic or in relation to this virus? 314 00:41:33,420 --> 00:41:40,260 I don't think it's this is incremental. This is a massive step change in terms of what you can answer. 315 00:41:40,800 --> 00:41:44,400 What it is a step change in is accessibility to it. 316 00:41:44,630 --> 00:41:51,930 All right. Induction of cost. And it turns it into an everyday commodity for that and anywhere in the world. 317 00:41:52,160 --> 00:41:57,420 Yes, it becomes agnostic. You don't have to have expert people to take. 318 00:41:58,080 --> 00:42:09,350 It's taking. You know, it's taking A to Z out of London and put it into Jeeps. 319 00:42:10,310 --> 00:42:15,770 That's what this is doing. So it's taking what a lot of people loved. 320 00:42:15,770 --> 00:42:21,940 It's having something you can have a hold and feel and look at and understand the concern. 321 00:42:22,810 --> 00:42:25,940 I could be rude about it and turn it into something. 322 00:42:25,940 --> 00:42:32,050 But this is digital, this intuitive. Ooh. That's touching point. 323 00:42:32,290 --> 00:42:42,100 So you've got people in Africa, Philippines, everywhere collecting samples and being able to extract it, to extract the DNA, presumably. 324 00:42:42,220 --> 00:42:44,410 Yeah. There's a lot of yeah, a lot of hard stuff to do. 325 00:42:44,410 --> 00:42:52,810 But once they've got a genome sequenced, the challenge was to take the genome sequence, as it implied, already assemble it. 326 00:42:54,130 --> 00:43:02,360 And then once you've assembled mining for the relevant pieces, after you've got the complete assembly in place. 327 00:43:02,830 --> 00:43:04,060 And then having done that, 328 00:43:04,210 --> 00:43:12,070 that you can analyse it and then tested to demonstrate that it's performing in the way that you want to perform against some standard. 329 00:43:12,880 --> 00:43:19,720 And we can do that now so that somebody's got this type of secrets or that type of 330 00:43:19,720 --> 00:43:25,990 sequence or this kind of method of preparing it and upload the information to the cloud. 331 00:43:25,990 --> 00:43:35,200 And it comes back with the answers. And that hasn't been possible without having an expert locally to do all of that stuff, 332 00:43:35,940 --> 00:43:41,980 work on the command line computer and even write a bit of code to make it work. 333 00:43:42,580 --> 00:43:47,870 This is. At Europe's. You want to go somewhere? 334 00:43:48,650 --> 00:43:52,129 That's how you go. That I've got this DNA sequence. 335 00:43:52,130 --> 00:44:00,770 What is it? Search thoughts. So the Oracle people are doing that work with with you, with group that we're providing. 336 00:44:01,790 --> 00:44:08,630 It's a partnership, actually. There's a whole lot of things that they do unbelievably better than we can never do software as well as they can. 337 00:44:09,290 --> 00:44:14,000 Although we are establishing a vehicle to address that. 338 00:44:14,750 --> 00:44:22,879 They donate T to Oxford to provide the tools that enables you to do those same 339 00:44:22,880 --> 00:44:30,170 decent analysis that they will provide the infrastructure on there in the cloud to 340 00:44:30,170 --> 00:44:37,010 process it and the software that enables you to configure those tools and make 341 00:44:37,010 --> 00:44:45,000 them scale so that you can go from a few at once to tens of thousands at once. 342 00:44:45,130 --> 00:44:56,390 And so if you want to run a million of these sequences on the tools that are available most places in the world now to get the answers, 343 00:44:56,930 --> 00:45:01,250 it might take you a month to run them. 344 00:45:02,750 --> 00:45:09,170 The ambition is to have it so you could run them in a day. I don't think they will. 345 00:45:10,190 --> 00:45:14,900 But less than a month away, much less than a. 346 00:45:17,260 --> 00:45:23,589 To me, that's sort of voodoo stuff because it means highly, highly, highly skilled people, 347 00:45:23,590 --> 00:45:29,770 of which there are not many that bring that together to make it perform in that sort of way. 348 00:45:29,810 --> 00:45:36,370 And so that's that's the difference. I don't I don't even get you more massive insights. 349 00:45:36,370 --> 00:45:39,550 You get more rapid turnaround. That would be incremental. 350 00:45:39,650 --> 00:45:48,190 Yeah. Yeah. So, I mean, another project of yours, which was, I guess, again, to do with speeding things up is the land pool. 351 00:45:49,240 --> 00:46:02,080 So did that come about? This was well, we work with Oxford Nanopore Company because they were quite very sweet and because. 352 00:46:05,830 --> 00:46:11,380 They've been sort of local originally a local tech start up and it's really brilliant. 353 00:46:13,180 --> 00:46:17,350 But they are annoying because they're so brilliant they can do all of this stuff. 354 00:46:17,830 --> 00:46:28,920 But they've they've been being quite reasonably, not that attentive to detail things. 355 00:46:29,260 --> 00:46:35,750 And of course, you tend to the new detail. They're getting much better at that, becoming a really professional outfit. 356 00:46:35,800 --> 00:46:40,460 And and they have got to take the group. 357 00:46:42,170 --> 00:46:50,370 Is more than likely to become the winning ticket at the moment to be it. 358 00:46:51,280 --> 00:46:56,530 So let's just go back to the beginning again. We have to bear in mind listeners who might not know the background to this. 359 00:46:56,610 --> 00:47:08,510 What what does that technology do? These are the technologies that take the nucleic acids or the DNA, 360 00:47:08,810 --> 00:47:25,100 RNA of an organism and then mix and process that material to generate an output, which is the sequence, which is the genetic code. 361 00:47:26,000 --> 00:47:33,020 And there are lots of ways of doing it at different levels with different machines. 362 00:47:33,020 --> 00:47:37,849 You can do it on each one of those different sheets. That's it. 363 00:47:37,850 --> 00:47:46,260 So in a very different way. And out of it would come the genetic code. 364 00:47:46,280 --> 00:47:55,280 So it's like if you like listening to music, you could have a radio produce, you could have a tape recorder doing it, you could have a turntable disc. 365 00:47:55,610 --> 00:47:59,350 And they've all got to have their own way of getting music. 366 00:48:00,020 --> 00:48:07,580 And it's a sort of range of devices that sequence that are quite different, that give you a sequence. 367 00:48:08,630 --> 00:48:17,480 And they they constrained by various limitations, each one of them, 368 00:48:18,290 --> 00:48:26,180 that they could slow to make it difficult to run or expensive to run exactly the same audio equipment, in a way. 369 00:48:27,020 --> 00:48:31,459 And Illumina is the most successful one. 370 00:48:31,460 --> 00:48:45,380 So what you might say is that they were like the Sony Walkman dominated the world and other little might come along and leapfrog over them, 371 00:48:45,380 --> 00:48:48,620 which is Apple. Well, in a funny way. 372 00:48:49,280 --> 00:48:56,120 Oxford, Nanopore is a bit like Apple versus Sony Walkman, which still dominates the world at the moment. 373 00:48:56,480 --> 00:49:09,590 I think that it's quite possible that that Apple will leapfrog because they've got some really huge advantages in terms of the speed, 374 00:49:09,740 --> 00:49:18,950 the terms of the cost takes to do it in this sense that it it's it's tiny, tiny miniaturised. 375 00:49:18,950 --> 00:49:25,700 It's small, it's fast, it's cheap. And what has been your role in the collaboration? 376 00:49:26,600 --> 00:49:33,549 Oh, we just worked with them a great deal and published a lot of work on that, of course. 377 00:49:33,550 --> 00:49:37,170 So when they came at that point, they said, look, we would be interested. 378 00:49:37,410 --> 00:49:40,490 Were it's a really neat technology. 379 00:49:41,210 --> 00:49:49,400 So you're testing it again to stop doing it. The government was invested in it and withdrew the investment and no idea why. 380 00:49:51,350 --> 00:50:05,210 It's a story yet to be told possibly. So it was a very, very, very smart way of doing testing that would be no better than a PCR. 381 00:50:06,200 --> 00:50:17,300 It would be faster than doing PCR, but just and it would integrate into into computer infrastructure, 382 00:50:17,780 --> 00:50:27,500 probably better than PCR is actually, funnily enough, a waste of the sequencing technology. 383 00:50:27,680 --> 00:50:31,700 So in some ways, as elegant as that solution was. 384 00:50:34,000 --> 00:50:44,709 The more elegant things that nanopore can can do by but gathering sequence in a more complete and comprehensive 385 00:50:44,710 --> 00:50:59,350 way to serve your lessons with lost San Francisco so is so the the land pool was great we did it very well. 386 00:50:59,350 --> 00:51:08,020 We worked with Sheffield doing it and got regulatory approval, but it would never roll it out. 387 00:51:09,860 --> 00:51:14,180 Are you still using it in your lap? No. You wouldn't do that by using the machine. 388 00:51:14,210 --> 00:51:17,030 The machine sequencing machines are still dead. We still use them. 389 00:51:17,040 --> 00:51:26,990 Yeah, we have just about for the UK Health Security Agency in our routine laboratory research. 390 00:51:27,320 --> 00:51:32,990 We help you with the routine that set up SARS-CoV-2 sequencing. 391 00:51:34,040 --> 00:51:42,629 So we setting it up to get trained in a standard way in the routine lab and that will process through this article. 392 00:51:42,630 --> 00:51:50,110 Related. Cloud peace. And that's an experiment to establish. 393 00:51:52,120 --> 00:51:56,080 Nanopore sequencing cloud results to. 394 00:51:59,320 --> 00:52:02,979 Hopefully a pretty straightforward, seamless way. 395 00:52:02,980 --> 00:52:09,190 So it comes off the sequence that goes through the cloud in about 15, 20 minutes. 396 00:52:09,880 --> 00:52:14,140 Currently, it takes about 4 to 5 hours to run this stuff through. 397 00:52:14,980 --> 00:52:25,690 And this is all got to do with having the compute and being able to parallel the witness data that you're running through that well, 398 00:52:25,690 --> 00:52:29,380 it probably will do it good. Start with smaller scale stuff that's here. 399 00:52:29,740 --> 00:52:39,190 It's likely that the Office of National Statistics samples that have the virus in it will get all sequenced, 400 00:52:39,820 --> 00:52:45,670 and we will probably do that at the moment studying Northumbria, and they do it very well. 401 00:52:47,860 --> 00:53:01,330 Um, but there'll be, you know, ongoing discussions where the Northumbria do focus on other stuff and whether we should do these research related ones. 402 00:53:02,090 --> 00:53:06,730 Yeah, I'm, I think we're pretty neutral for what needs to be done from. 403 00:53:08,970 --> 00:53:09,840 For Battlefield.
