Will we need coronavirus vaccinations every year? How will variants affect immunity and new shots? Here's what we know.
The companies are also investigating whether a booster shot of the same formula will do the trick, or if their current vaccines need to be tweaked to better take on the variants. Additionally, the National Institute of Allergy and Infectious Diseases is— if boosters are, indeed, necessary.
And those are just some of the questions that linger about COVID-19 variants what they mean for our collective immunization efforts — and for the pandemic as a whole.“We know increasingly reassuring information about durability, but the variant question remains open,” Wolfe said. All of which points to the pressing need to get as many people around the world vaccinated as soon as possible in order to stop the virus from spreading and evolving as it does.“Pharmaceutical logistics and how they need to study a new booster, how they need to go into production and whether it’s efficient for them to try and combine those with alternative vaccines” will all play a role in the timing of potential COVID-19 boosters, Wolfe said.
But while planning and thinking ahead is important, experts say it is even more critical to focus on the here and now, particularly as variants like delta circulate and new variants arise in people who are unvaccinated.Experts are still learning about COVID-19. The information in this story is what was known or available as of publication, but guidance can change as scientists discover more about the virus.
