From here it all began. The virus that entered the country took over the DNA and became a variant. The area became a red zone for the first time and therefore protected in their opinion. The vaccine generates a complex response to many areas of the Spike protein ", so" even if there were some antibodies not able to recognize a mutated area such as that in position 501 or 493, there would certainly be others able to bind to unchanged portions of the protein. Their binding would be sufficient to prevent the interaction between Spike and cellular receptor, even if only for a sort of 'steric hindrance' that the antibodies would create on the surface of the virus. In a short time, however, we will have a certain answer to this question ".
