Some posters seem to believe the booster is just another shot of the same vaccine. This is only certain now for those deemed to have compromised immunity. The booster when released for the rest of us might be the same, the same at a lower dose or one modified for the new variants. For those who want a link to the source just Google some of the text below.

Is the booster just a third shot of the same vaccine?
We asked Johnson and Johnson, Moderna and Pfizer, the answer is both yes and no. That's because they have several boosters in the works.
Pfizer and Moderna are looking at offering a third dose, same as the first and second, while at the same time testing other ones engineered to specific variants.
Pfizer is currently evaluating a two-dose series separated by 21 days, and prototypes geared toward the Beta and Delta variants.
Moderna is evaluating their original formula given at different doses, specific variant options and a "multivalent platform, combining different variants into a single vaccine."
"The goal of the multivalent platform is to continue to try and stay ahead of where the virus is going by combining different antigens against emerging periods of concern," Moderna President Stephen Hoge said during an earnings call.
