The biopharmaceutical industry will be able to make a Covid-19 vaccine—probably a few of them—using various existing vaccine technologies. But many people worry that Covid-19 will mutate and evade our vaccines, as the flu virus does each season. Covid-19 is fundamentally different from flu viruses, though, in ways that will allow our first-generation vaccines to hold up well. To the extent that Covid does mutate, it’s likely to do so much more slowly than the flu virus does, buying us time to create new and improved vaccines.
Rest assured: a vaccine is coming, it will work, and it will continue to work for as long as humanity must contend with Covid-19. Until then, we must maintain our social distancing so that our strained health-care system can keep up with the infections that we can’t seem to prevent.
