CDC weighs in that boosters don't seem to be needed or no evidence at this time. Agree and I summarize some of the T cells/B cell studies in the paper below in next tweet but want to add a few more!

Here is the paper where I tried to put some of this together but 3 more EXCELLENT studies that came out since wrote this that add to the idea we won't need boosters (at least anytime soon!)

One paper that didn't get into the summary above shows that memory B cells formed from even mild COVID (other papers have shown this) but then they were tested to see if they produce antibodies specific to a variant if they see a variant & they do

Another is here from @UCSF showing that T cells mature into "memory T cells" even after mild infection which last a long time

And same after vaccination - again, showing evidence that 1 vaccine after natural infection is likely all it takes. Memory T cells formed (those last years and years):
