The acquisition of immunity due to vaccination and direct infection with a coronavirus infection caused mutations in the gamma strain. This was announced by Brazilian scientists, writes the Virological discussion forum. According to virologist Felipe Navek from the Osvaldo Cruz Research and Production Association under the Brazilian Ministry of Health, it is most likely that it was the acquisition of immunity as a result of vaccination and direct infection that caused mutations in the gamma strain. Scientists are now studying how infectious the new generation can be among vaccinated individuals. It is noted that one of the mutations has common features with "Delta". Scientists are convinced that new types of mutation can spread throughout the Amazonas and become dominant species, as previously happened with the gamma variant.
