I think everyone knows by now that all discourse surrounding the pandemic has been completely politicized since day one. And it has significantly worsened since the introduction of the vaccines. The moment we knew that all the vaccines are "leaky,"[1][2][3] the battle was effectively lost in most countries because the kinds of percentages it is going to take to control the virus is only possible in wealthy, authoritarian societies.[1] > For example, one calculation suggests that for a vaccine that totally eliminates transmission, 60-72% of the population would need to have it, it order to accomplish complete herd immunity. But if the vaccine’s effectiveness were 80%, between 75 and 90% of people need to have it. Which explains all the coercive measures being taken against un-vaccinated and vaccine-hesitant people in the West and the sudden itch to control "misinformation" on social media.

  75% to 90% is not impossible in reasonable countries. Many childhood vaccines are expected to be administered to at least 95% of the children. There are two promising aspects. Vaccination after infection boost antibody levels and is providing very good protection. Infection after vaccination is also boosting antibody levels to similar level and there is hope the it also gives very good protection.
