RE: Evolutionary master viruses

Viruses, as Darwin wrote in his theory on species, practice adaptation to survive, create new organisms with different characteristics in order not to disappear, for this reason the use of antibiotics is limited to a certain time, otherwise it will become harmless since the virus it attacks will reproduce with the variant of immunity to it, now when it comes to immunizations as in the case of covid, vaccines, which are manufactured containing the virus generally achieve the goal of preventing the disease from becoming serious.
