Currently, people who want to be fully vaccinated against COVID have to first get their primary vaccinations — two shots of the original vaccine spaced weeks apart. That's followed at least two months later by a booster, currently the bivalent shot that's tailored to protect against omicron.
The agency notes that if a more dangerous COVID variant were to emerge, it might reconsider the vaccine strain at other times of the year on an"as-needed and emergent basis." "The public is voting with their arms if you will and said, 'No. I'm not going to get this. This doesn't make sense to us,'" says Dr.While endorsing continued boosters for those at high risk, such as the elderly, some question whether the current bivalent vaccines updated to target omicron have enhanced protection compared to the original vaccines. Most people are still well-protected against severe disease by the immunity they already have, they say.
Another concern some researchers have is that the FDA continues to rely on antibody levels to test vaccine efficacy.Eric Rubin , an immunologist at the University of North Carolina, Chapel Hill."And that will be good enough. It would probably benefit most people."Some researchers think it's too soon to rely on annual boosters. COVID hasn't quite settled into a seasonal pattern like the flu, they note, and the SARS-CoV2 virus is changing more quickly than the flu virus.
