An incredibly slippery slope for something of dubious value. If what we are being told about vaccinations is correct, the primary threat is to the unvaccinated. In the US, vaccines are widely available and cost free. The only people over the age of 12 who are unvaccinated are that way by choice. So they have put themselves in harms way.
Furthermore, recent studies have tended to show that vaccinated people can carry and spread a viral load equal to the unvaccinated. That means that the threat a vaccinated person creates in spreading the virus is equal to that of the unvaccinated. Therefore, being vaccinated only benefits that individual, not others around them.
