If the majority of the world is unvaccinated, this will be a constant plague on all of us with new variants occurring constantly.
Hey poor countries- You ain’t missing much.
Many researchers are studying which mutations lead to more transmissible versions of the coronavirus. It turns out that variants have tended to have many of the same mutations that increase the amount of virus an infected person produces. With more than a million new infections occurring every day and billions of people still unvaccinated, susceptible hosts are rarely in short supply. So, natural selection will favor mutations that can exploit all these unvaccinated people and make the coronavirus more transmissible. Under these circumstances, the best way to constrain the evolution of the coronavirus is to reduce the number of infections. The delta variant has spread around the globe, and the next variants are already on the rise. If the goal is to limit infections, vaccines are the answer.
