We indeed don't know that much about the virus itself, what happens when one gets infected multiple times and when multiple vaccines are combined. We are going to find out either way. The goal of the vaccines and the other containment measures is to keep our health systems from collapsing. Whether or not we manage to eradicate Covid or to just force it into low-level virulence is not so important. It is probably not feasible to convince the public to hunt down Covid to extinction as with Smallpox.
1. Provide vitamin D3, zinc, and some zinc ionophore to the masses and advertise the benefits. Also, advise people to take a baby aspirin daily (slows viral replication and prevents blood clots).
2. Just like with cigarettes, have highly visual ads presenting the data that about a third of men have ED problems after surviving COVID-19. I think this would work better than anything else!
3. Have a ongoing campaign in prime time showing how to properly wear a face masks, what's the difference between a cloth one, a surgical one, and N95 - people still can't wear masks properly and have no idea what's the difference between a cloth one, a surgical one, and an N95/KN95/KF94/FFP2/FFP3.
Not sure if vaccines prevent any of this.
They surely prevent damage by reducing infection rates in fully vaccinated, but not sure if they can save you from damage, same way they are saving you from death if you contract the virus anyways.
