Omicron variant more resistant to vaccine but causes less severe Covid: study
Is it just me or does it make perfect sense that the selection pressure would push the virus to do this? After all, it’s competing against other variants, as well as counter measures by other human beings.<p>I imagine even that the cold and flu may have started out thousands of years ago as much more deadly, even fatal, but that over the millennia the same process occurred.<p>Perhaps in the case of COVID the process is just greatly accelerated due to air travel, as well as existential threats to the virus’s well being, like vaccines and lockdowns.<p>Is there some kind of law in biology that predicts contains become more virulent and less deadly over time?
