If you've had at least the primary series of any of the vaccines, you are 12 or older, and it is 2 months since your last dose, go and get the updated boosters!
These updated boosters are bivalent- half the mRNA codes for the spike protein of the ancestral Wuhan strain and half codes for the spike protein of the circulating Omicron sub-variants BA.4/BA.5 (BA.4 and BA.5 have identical spike proteins).
Don't worry if you only had 0, 1, or 2 boosters before this. Up to date on coronavirus vaccination now means you received the new updated bivalent booster.
If 80% of eligible people get these updated boosters, we can avert 160k deaths, 1.7 million hospitalizations, and avoid $109 billion in medical costs through March 2023.
I've seen appointments available online at CVS, Walgreens, and Stop & Shop.
