Experts discuss the potential need for more boosters and what the future of COVID-19 boosters might look like.
? Should we be prepared to get boosters for the next few years until COVID-19 is fully under control? Or will we need an annual shot, like the flu vaccine, for the rest of our lives?
Right now, experts don't know how many COVID-19 boosters we'll eventually need or how frequently we'll need to get them. But there are some key factors that they're paying attention to in order to figure that out.Boosters are designed to do exactly that — to boost your body’s initial response to a vaccine and provide more protection against a particular pathogen. And it’s not that unusual for a vaccine aimed at preventing a viral illness to require boosters, Dr.
Researchers are looking at two major factors that will determine whether or not we'll eventually need more boosters. First, does the protection provided by the vaccines wane over time? And second, are the current COVID-19 vaccines still relatively well matched to the version of the virus that’s circulating right now?
If the protection dissipates over time, as appeared to be the case with the initial two-shot doses, then we might eventually need another round of boosters to amp up our immune responses.
