Quartz: Has Covid-19 permanently altered the development timetable for other vaccines?
“Creating vaccines, experts were careful to remind us at the beginning of the pandemic, takes time. It took two decades for researchers to develop a vaccine for polio, in 1953, and even longer to get a chickenpox vaccine, in 1995. … In more recent years the vaccine development timeline has been shortened and in some cases is now less than five years — the vaccine for SARS, for instance, was in development for two years. That was the timeline experts were expecting for Covid-19, too — but surpassing even the most optimistic expectations, it took less than a year to deliver the first vaccines…” (Merelli, 12/15).
