The mRna immunity seems to fade at about 5 months. I hope that boosters will be available at six month intervals.
The media is surprisingly nebulous about the vaccine doses. I'm guessing most people have no clue of the dosages in the vaccines. I'm personally waiting to get a booster as I'm not at high risk for severe disease. I might wait until I'm 60+ to get another vaccine.

Quote:If you had Moderna for your first two shots... you might consider getting the Pfizer booster because it's a smaller dose (30 micrograms) than the Moderna booster (50 micrograms).
