I also had no side effects of the latest booster. Earlier doses have me some arm ache, but that seemed irrelevant vs the benefits.

I get a flu shot every year and have no concerns over repeated Covid shots.

Also, never had Covid, In part because I don’t want to be responsible for giving it to someone with a weakened immune system. People who look at vaccination only in terms of their own risk/reward calculus are failing the communities they're part of
