No, unless you can not count, it is entirely reasonable to discuss even in short-form forums like this.

For a modern complex civilized society to continue to exist, everyone must make accommodations.

Demanding absolute perfection and zero issues with those accomodations, as you are doing by handwaving about "define" and "100%", is what is unreasonable.

When the lives saved are in the billions, enough to cause a population explosion fundamentally change the structure of society such that e.g., women no longer need to have a dozen kids to have one or two children make it to adulthood, and the safety is so good it takes massive studies to even identify possible marginal issues in one in several million vaccinated, and the consequences of not requiring simple accommodations like taking a vaccine (w/obvious medical bona-fide exceptions) or quarantining to prevent a pandemic or outbreak of a deadly disease, there is no reasonable debate. It is reasonable to require such things to participate in the society.

The people refusing are simply freeloading on the herd immunity and healthcare system built and maintained by their smarter and more conscientious peers.
