“New vAriante Sudafricana? We still don’t know what will happen, but we have to get used to the idea that we will see viruses emerge with numerous mutations. But until we have variants they are able to escape vaccine immunity and of transmit more than the Delta variant, we don’t have to worry too much. Today, fortunately, it is the variant Delta the firing range of vaccines “. Are the words spoken to “Half past eight” (La7) from Marco Cavaleri, Head of Vaccines and Covid-19 Therapeutic Products of the European Medicines Agency Mom, about the new South African variant, which has 32 mutations of the Spike protein.
Cavaleri points out: “We certainly need to be vigilant and attentive and above all to have a system that is able to see when these variants emerge and then immediately take action if these variants have the possibility of spreading. This variant, in particular, was seen in South Africa in about ten cases, so we don’t know if this variant will spread. However, we know for sure that numerous variants, even if they have many mutations, it is not certain that they will take over and become the predominant strain – he explains – Remaining in South Africa, for example, the Beta variant it was one of the first to come out and it worried us a lot because it had some important mutations in the Spike protein. D.i fact, this variant is gone, because it has been supplanted by vDelta soaring, which is much more transmissible“.
