I am about to bang my head against a brick wall over the number of people here who do not want to see restrictions relaxed unless there is 100% protection, zero cases, or some other absolute. Folks, that is unattainable. It will never happen. There will always be a chance you may catch Covid. There will always be a chance you might even die from it. Eliminating that risk is not the point. Getting the risk to a manageable, acceptable level is.
The data shows that once you are vaccinated, the risk of catching, spreading, or having serious complications from Covid drops to virtually zero. No, not absolutely zero. Yes, there's still a slight chance you could get sick or spread it. Yes, there's a slight chance a variant might pop up that beats the vaccine. But it is the closest you can possibly get to complete protection.
Again, my opinion is that if you want vaccines in arms, you have to tell people that they can get vaccinated and then drop the restrictions. Nothing else is going to sell it on the scale we need.
