>It doesn't have to be rational. Vaccines mandates are already common for school children, nurses, (and maybe teachers, but I'm not sure about that one)
Even this argument ignores nuance.
The vaccines in these schedules are mandated for 2 reasons
1. The diseases they treat directly impact their population in a major way in large numbers
2. Immunization not only prevents the negatives impacts of 1, but also prevent the spread.
As an exmaple for #2. Take Pertussis and TDAP. Even adults that have children will often get a booster. The reasoning is sound there, you reduce the chance of transmitting pertussis to an infant. This is especially true for premature babies that may not have had the chance to get the anitbodies from the mother, assuming she got a booster during pregnancy.
As of right now. COVID-19 has a pretty small impact on children directly ( hospitalization rates at their peak were like 1.9 per 100k for under 18 [2]) . And even nationally its much smaller than any of the diseases used to compare it to (like Measles which has pretty severe complications in like 30% of those that contracted it, regardless of age [1])
AND the vaccine isnt particularly proven to reduce spread [3]. To add insult to injury, CDC specifically stopped even recording breakthrough infection rates unless they were severe as of May 1, 2021.
So it would make sense to question a vaccination mandate for those under 18...
