Dr. T:  What are your thoughts about Moderna boosters.  It seems logical to me to wait until the boosters are approved, but, on the other hand, that seems inevitable.  I got my 2nd of the two shots in mid-March.  No real significant co-morbidities except for having a hyperactive fork and being 68 yrs. old.

Moderna has a higher dose of spike protein that might account for slightly higher reaction rates than Pfizer. I prefer Pfizer simply for that. But the vaccine essentials very similar In any event , I would get a mRNA booster as soon as you can at the closest facility offering either. The purpose of the booster is to reinvigorate the memory B cells that make antibody against the spike protein. Natural immunity makes lesser degree antibodies against a variety of different viral antigens which may account for lesser more variable response by the previously infected. Boosters are just that, inciting extra antibodies when you might need them
