I've already wrote enought about this topic, I won't repeat myself. You're looking at the problem from a different angle than it should be looked at in my opinion. We've already established that the transmission and severity are effected with vaccination. But severity isn't a problem in most demographics and consequently the transmission shouldn't be the focus of the problem. Focus on those who are the most endengared. Look at the data of hospitalizations, severe cases and deaths. You'll get a clear picture who needs protection.
There are multiple problems with this approach in my opinion
-more unvaccinated people means greater risk of mutation and more difficult to control strains emerging
-the effects of long covid adding more cost to the healthcare system. People developing conditions post covid. These people will need to be treated the rest of their lives
-what about health care workers and others that work with high risk populations? Shouldn't they be mandated to be vaccinated to protect those under the care?
