I don't see why people should be given the freedom to go about infecting others with a potentially deadly virus.
Normally, I'm all for freedom of choice and against anything compulsory. Still, in present (abnormal) circumstances, I think the unvaccinated (rather than the vulnerable) should have their freedom restricted. Access to bars, restaurants, hotels, air travel, indoor events, gyms and pools etc. isn't necessary for life, after all.
Responsible folk have been vaccinated, not just for their own safety, but for the welfare of others, too. They're less likely to catch the virus. If they do, they're less likely to transmit it:
