Whoever refuses to be vaccinated puts not only his own health at risk, but also that of others. That’s because variants can only develop in the body of infected people, a risk that obviously increases if you don’t get vaccinated. “Unvaccinated people are potential variant factories,” William Schaffner, professor of infectious diseases, told CNN
“The more unvaccinated people, the more chance for the virus to multiply.” And when that happens, the virus mutates and can deliver a more serious variant somewhere along the way.”
That’s what viruses do: mutate. A virus wants – if everything living, survives as a species. So when one way is closed by vaccines, the virus finds other ways. If the mutation can spread, a new virus variant emerges, which may be more contagious, replicate more efficiently, or infect a greater diversity of hosts. Such a variant can then become dominant, as is now fully underway in many countries with the Delta variant.
For the time being, the vaccines still hold up against the current variants, but that is not a certainty for any new variants. That is why high vaccination coverage is so important now. And wappies and believers are therefore a danger to all of us
