I always knew that immunity was never a certainty, having never been tested in human beings before. I was more confident that it wasn\u2019t a dangerous thing for me to do, and certain that it was a <\/span><i><span style=\"font-weight: 400\">good<\/span><\/i><span style=\"font-weight: 400\"> thing to do.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">And by participating, I have certainly helped to prove both of these latter points. I\u2019ve had two shots of the vaccine, which works by instructing my cells to make fragments of the coronavirus, thereby prompting my immune system to react and, hopefully, keep a protective memory of the threat. I\u2019ve had no side effects at all; not even a sore arm. The devil on my shoulder sort of wished for even a little redness where the needle went in, that I could wear proudly as a mark of my contribution to research.\u00a0<\/span><!--more--><\/p>\n<p><span style=\"font-weight: 400\">Alas, though, everything has been very placid and uneventful, which is a good sign that I\u2019m thankful for. And my experience \u2013 and that of fellow participants \u2013 has built important evidence that this vaccine is very safe. \u201cWell-tolerated\u201d is the technical term I read in a letter I received during my 8th visit to the trial centre.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">As my eyes crisscrossed down the page, I initially felt my heart sink a little. Everything in the letter about the trial\u2019s progress was encouraging, although I couldn\u2019t help but focus on the point that at the highest dose trialled so far, participants\u2019 immune responses may not be as strong as was hoped. Although the team tells me that the dose I received could still be protective, they say they would have more confidence if the responses were higher with higher doses. <\/span><span style=\"font-weight: 400\">So the trial will continue, now recruiting a new group of individuals to test different doses, in the hope of stirring the immune system into more rigorous action.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">My invisible bubble of feigned immunity popped. It\u2019s probably for the best.\u00a0<\/span><\/p>\n<h2>Finding a coronavirus vaccine: it\u2019s not a race<\/h2>\n<p><span style=\"font-weight: 400\">As participants, we have all given a lot to the trial; time, effort, blood \u2013 around 70 test tubes, each, to be precise. But not as much as the trial team, who have been working tirelessly since the early days of the pandemic to bring forward a technology that could be a game-changer in the fight against COVID-19.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">So of course I wanted this vaccine\u2019s journey to be a straight Roman road to success, rather than the traditional windy path of research. Not for selfish reasons, but because we all so desperately \u2013 even if credulously \u2013 seek a silver bullet to end this wretched disease.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">But this is how trials work. During the early stages of any new medicine\u2019s development, researchers need to find out whether it\u2019s safe, and also work out the best dose to use. So the exploration of new doses is standard procedure. Getting the dose spot on first time with an experimental drug would be remarkable. The fact that this vaccine has come this far in such a condensed timeframe is, however, pretty remarkable. And the team has told me that although the immune response might not be strong enough yet, they\u2019ve seen promising signs that stronger doses produce bigger reactions.<\/span><\/p>\n<p><span style=\"font-weight: 400\">\u201cThis is a new technology,\u201d Professor Robin Shattock, who developed the vaccine, told me. \u201cSo we need to make sure we get it right, rather than rushing to be first.\u201d<\/span><\/p>\n<h2>Testing times continue<\/h2>\n<p><span style=\"font-weight: 400\">Outside of COVID-19, we would not consider it a bump in the road that scientists are playing by the regulations and protocols that are there to protect people. We would be lauding them for putting safety before speed. And that\u2019s what we should do now.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">\u201cNow that we have established that our vaccine has a good safety profile, and we\u2019ve seen a clear \u2018dose-response\u2019, we want to maximise its potential by exploring additional doses,\u201d said Prof Shattock.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">\u201cThis is a pioneering technology. It\u2019s scalable, easier to manufacture than many others, and we believe it can be given multiple times \u2013 as many times as necessary.\u201d\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">That\u2019s a really important point, I learn, because it\u2019s widely believed that no vaccine can offer a lifetime of immunity from a single shot. So giving the immune system friendly reminders in the form of boosters can enhance the chance that immunity will be long-lasting.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">So although the trial has been pushed back slightly, it\u2019s still on track, and should be considered as a sign of scientific integrity. There is a tale of a tortoise and a hare that seems particularly poignant today.
