@markd @alwirtes @overholt TIL! Thank you for the information.

@alwirtes @overholt Similarly, I had all my vaccines in childhood, but (without bothering with a test) I got an MMR and a Tdap in the last year because I work with young people and I don’t want to be an asymptomatic spreader of anything.

Hearing people talk about feeling side effects from either is a bit of a wake-up call. I had zero side effects, which may mean my immunity had waned significantly!
