Thread: You may have heard of #COVID-19 vaccines in advanced clinical trials—Moderna, Pfizer, AstraZeneca and the like. But there’s a huge second wave of vaccines on their way. nytimes.com/2020/08/27/hea… [1/7]
I recently decided to take a look at this second wave. I reached out to all the companies and universities I could find that have announced preclinical studies since the beginning of the pandemic. [2/7]
I was able to confirm that 88 vaccines are still being actively investigated at the preclinical stage. Of these, 67 are on track to go into clinical trials in humans between now and the end of 2021. [3/7]
That’s a lot of vaccines! By comparison, 35 vaccines are now in clinical trials. Only 7 are in Phase 3, the final stage of testing. We could be looking at 100 trials in the months to come. [4/7]
But you might think, aren’t we a few months away from the approval of at least one vaccine? We may well be. So what’s the point of toiling away at another vaccine—or 88 vaccines? [5/7]
Well, there are a lot of answers to that question—because there are a lot of different kinds of vaccines in the works—nanoparticles, recoded viruses, bacteria studded with viral proteins, and more. [6/7]
