Parents shouldn't be allowed to veto healthcare based on personal beliefs

We can't let parents stop their kids from getting whatever healthcare they need because they think that vaccines or blood transfusions or anything else are morally wrong or "harmful" because they're scared. What they think is irrelevant. If there is a scientific consensus on the benefits of a certain treatment then a parent shouldn't be able to say "no" because they think it's "controversial" or "experimental" or whatever the fuck else they want to whine about.

This goes double for teenagers who should absolutely have enough bodily autonomy to make these decisions.
