Not only will a booster with the new vaccines decrease the likelihood of infection and severe illness and help reduce transmission of the virus; it could also decrease the likelihood of developing long Covid.

And these new boosters can be expected to do even more going forward — including providing better protection against future variants, by better training both antibodies and memory cells, which are different parts of the immune system.

As Bhattacharya told me, being exposed to different versions of the virus (as will happen with these updated boosters) further deepens and broadens the kind of antibodies that get generated, including ones that can work against future variants.

Marion Pepper, an immunologist, told me a new variant vaccine can also “create new, more diverse memory cells that will help protect from Omicron variants and new variants that we have yet to encounter.”
