The new approach would simplify vaccination guidance so that, every fall, people would get a new shot, updated to try to match whatever variant is dominant.
Under the new approach, most people would be advised to simply get whatever the latest version of the vaccine is annually each fall like the flu vaccine. They wouldn't have to worry about how many shots they've already gotten and which one they got when.
"As far as the tools that we have right now, I think it just makes the most sense to plan to update each year as close as we can to the currently circulating variant," says "We shouldn't really be chasing these variants, which are evanescent and are often gone by the time you've created the vaccine," says Dr.Offit and others also question whether everyone will necessarily need to be boosted regularly, or just those at high risk, like the elderly.Critics of the FDA's proposed new strategy argue it would be better to invest in developing better vaccines that might be more appealing to people, and in campaigns to get more people vaccinated.

For instance, Rubin says the FDA should require proof the updated vaccines are actually reducing the risk of getting infected, getting sick, hospitalized and dying. , an immunologist at the University of North Carolina, Chapel Hill."And that will be good enough. I 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.
But unless some more dangerous version of the virus suddenly emerges, the world might finally be settling into a more predictable co-existence with the virus. The federal official NPR spoke to says the goal of the new vaccine strategy is to make the vaccines, which are the major weapon for protecting ourselves, simpler and hopefully therefore more appealing. The latest boosters have found very few takers.
