Many people are worried about where these new strains come from and do they really exist at all? There are some big studies on this topic, here (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4516275/) is one of them. “Could some vaccines stimulate the evolution of more virulent pathogens? It is generally accepted that natural selection removes highly lethal pathogens if host death significantly reduces transmission. Vaccines that keep the host alive but still transmit the pathogen can allow highly virulent strains to circulate in the population. Immunity caused by direct vaccination or maternal vaccination prolongs the survival of the host but does not prevent infection, viral replication or transmission, thus prolonging the infectious period of strains that would otherwise be too lethal to survive.

The data show that disease-free vaccines that do not prevent transmission of the virus can create conditions conducive to the emergence of strains of the pathogen that cause more severe disease in unvaccinated hosts. There is a theoretical hypothesis that some types of vaccines can stimulate the evolution of more virulent (“hot”) pathogens.

This idea follows from the idea that natural selection removes strains of pathogens that are so “hot” that they kill their hosts, and therefore themselves. Vaccines that allow hosts to survive but do not stop the pathogen from spreading reduce this selection, allowing hotter pathogens to evolve.

This type of vaccine is often referred to as a "leaky" vaccine. When vaccines prevent transmission, as with almost all vaccines used in humans, this type of evolution towards increased virulence is blocked. But when vaccines leak, allowing at least partial transmission of the pathogen, they can create environmental conditions that will allow new strains to emerge and survive. " We understand that the Nobel laureate Professor Luc Montagnier said that it is the vaccine that creates new options. In an interview (deleted from all Big Tech platforms), he argued that for this reason, including the mass vaccination program, is a "huge medical error."
