I haven't had my vaccines "updated" in years, until I've enlisted in the military a few months back, be it in the reserve, but still.
Me and my group got like 5-6 vaccines, dispersed over a 2-4 week period.
Nothing against covid but regulars like tetanus and ticks.
Makes me wonder what the trade-off's of those are.
That would be interesting know. I haven't seen anything that really talks about adult vaccinations other than Covid.
Edit: We did use flu vaccines as an example of selection bias in an econometrics course.
