Can you please explain more?
Why can't both hosts A and B both be vaccinated folks?
Is'nt there a 3rd category - those who have immunity via past infection? How do it work in that case?

If what you say above is correct, then why do we see new strains in flu?
Has'nt pretty much every person on earth been exposed to flu or vaccinated against it?
- XorNot 5y agoIf host A and B are both vaccinated, then either the virus has achieved vaccine escape (it is spreading amongst the vaccinated population effectively), or if it hasn't then it still dies out. If 1 vaccinated person infects another say 3, but then those people fail to infect anyone else - then it doesn't actually matter what selective advantages that viral strain had - 100% of the virus has died out. But if the same chain terminates in the vaccinated people then infecting an unvaccinated person...then the new mutation escapes and potentially becomes dominant within the reservoir (unvaccinated people) and a failure to spread through the vaccinated population doesn't lead to the destruction of the mutant strain.
- foolinaround 5y agothank you for explaining this. Is there some literature that provides a reasonably clear explanation ( ELI5) around this. the next question is what happens to those with acquired immunity, and why are they being forced to be vaccinated? I see many studies that show that their levels of antibodies seem to be even better than ones from the vaccines.
