The Food and Drug Administration last week expanded its emergency-use authorization for Covid vaccine boosters to all adults over 18.
The Centers for Disease Control and Prevention agreed, also recommending that all fully vaccinated adults over 50 receive it.
If you are over 18, haven’t had Covid-19, and received your first shot more than six months ago, you should get a booster.
A new study in Nature demonstrates that the viral load decreases after the booster, which should mean a lower risk of transmission in a breakthrough case.
The side effects of boosters were similar to those from previous vaccine studies, mainly irritation at the injection site, fever and fatigue, but no evidence of myocarditis.
