I'm pro-vax (god, why do I have to say that?) but what's seriously pissed me off about this whole COVID thing is how quickly it became political. At the beginning there was a real sense of "we're in this together" but now you can be pretty certain of someones political affiliation if they choose not to wear a mask.
Vaccines prevent you getting the worst of the illness, they don't really prevent you catching and infecting others, so vaccines are a "cure" for overwhelmed healthcare systems and a protection for the individual.
So why do you need to have a vaccine pass to go places? You can still carry the virus and infect people.
Having unvaccinated parts of the population means we can track if it was the wise decision or not, hindsight is 20-20 and it seems obvious to me now that we should vaccinate.. But it also seemed obvious in the 50s that fireproofing buildings with asbestos was the right decision too.
