1/Please understand this. If coronavirus is allowed to circulate freely in a population which is mostly not vaccinated it has a bigger chance to mutate as we can see happening now. Itâs bad news if mutations lead to vaccine resistance. Then even the vaccinated wonât be protected.
2/The other problem with âfocused protectionâ is it doesnât account for the amount of illness generated by covid in those who donât die from it. Letting the virus spread widely will not take us back to our old lives. It will overload the health service & cause workforce paralysis
3/The solution is to vaccinate most of the population as quick as possible. Then the virus wonât know where to go. Until this is achieved, apply structural & behavioural changes to reduce transmission and generously support people who isolate. I really canât see another way out.
