If you were vaccinated with Pfizer it may be time to look at getting a booster. After around 6 months, the Pfizer vaccine may only be about 40% effective at preventing infection, although it’s much more effective at preventing severe disease and death. Well, apparently the booster takes it from 40% to 95.6%! You can be bulletproof again!

The article says that the FDA has also authorized a Pfizer booster for people who have had Moderna and J&J vaccines.
My doctor likes Moderna the best, and my third shot, and his, was the original 100 microgram (mcg) dose of Moderna. That’s two times the 50 mcg that Moderna’s recommended for their booster. This is not approved by the FDA and CDC. But I love vaccines and relish being a human Guinea pig.
