The Nuance
Is a Covid-19 Vaccine Actually Possible?
Experts are optimistic, but new vaccine ‘platforms’ are relatively untested
Since the earliest days of America’s Covid-19 crisis, Anthony Fauci, the White House’s top coronavirus expert and director of the National Institute of Allergy and Infectious Diseases, has said that — best case scenario — a vaccine could be ready within a year to 18 months.
In an interview published on June 8 in the Journal of the American Medical Association (JAMA), Fauci stated that if one of the several vaccines currently in trial proves effective, hundreds of millions of doses could be ready by early 2021. “I’m cautiously optimistic that, with the multiple candidates that we have with different platforms, we’re going to have a vaccine that shows a degree of efficacy that would make it deployable,” he said.
Fauci’s mention of different “platforms” may not have meant much to lay readers. But the scientific community is intensely aware of these next-gen vaccine-development technologies and processes that Fauci was talking about. The vaccines that these new platforms aim to create are easier to produce quickly and in volume, which is one reason why the usual “decade or more” timeline for vaccine development has shrunk to less than two years.
