Done.
However, I would say mass vaccination was a good but flawed and necessary policy. We still have Omicron sub sub variants. Notice that the variants are not broad and wide ranging so it is not from the unvaccinated who have a broader response. It is the vaccinated driving the micro level changes to the Omicron. But .. on the other hand the virus has become more manageable which is good and I am happy about that... But if we look closer that is not a 100% flawless strategy. It is endemic. The antibody titers are holding the virus in the upper respiratory tract so the fatality is low, but...there is a risk that the virus overcomes this target strain of specific non neutralizing antibodies and fatalities "could" climb for the vaccinated. But the good news is that they still have a Tcell response and treatments like Paxlovid are available. Anyway, the goal posts have moved on the final solution for Covid but at least we are generally improving the situation even if is flawed.
And the last point, generally a virus becomes less lethal so that it can survive. But if a virus is present in everyone who is vaccinated due to the non threatening nature of the non neutralizing antibodies. Does it harm the virus if it starts to kill 1% of the population? Don't be shocked to see a virus inflict creative ways to kill if we used a creative way to contain it.
