I don't get the flu shot anymore. I did, but I started paying attention the strains they immunize against versus the prevalent strains of that year. In the past 6 years, they've been wrong 4 times, only had one of the two prevalent strains in a 5th and had it right in one of the 6.

Not good enough odds in my book. But the mindset is the same. Beyond "herd immunity", there is "herd mentality". People get incredibly vitrolic when the subject comes up. We do vaccinate our children, and when I'm traveling to a foreign country with a new risk, I get vaccinated for that (like Hep C when I go to China).

But people start sputtering with rage, screaming at the top of their lungs "the science! the science!!! Get a flu-shot you flat-earther!!!

Nothing special about this issue. It has been my experience that we are becoming so closed minded and fear driven, we are losing the ability to have reasonable discourses. The concept of "agree to disagree" seems to be lost forever. Everything has become a blood feud.
