Genomic surveillance and precautions

According to José Eduardo Levi, coordinator of the Genomic
Surveillance Scientific Project (Genov), 11 of the 1380 analyzed between May and June had a mutation called P681H, in which the amino acid proline is replaced by another one, histidine, and is being called Gamma plus.
The Delta variant is already spread across the country with a record of 760 cases up to 5 days ago, however, Gama-plus: “a convergent mutation with a characteristic of Delta, a variant that usually presents this structural change” said the project coordinator Genov.
Many experts have warned that easing may be premature, and we may have to live with restrictions for a while, although the rate of vaccination has advanced, it still does not have a sufficient safety margin beyond the risk of new variants.
The death of actor Tarcisio Meira from complications of covid-19, having taken the two doses of the vaccine, rekindled the debate on the effectiveness of vaccines, but experts are categorical in saying, based on studies by USP and UNESP, that 91.49% of those who died did not have the second dose or the single dose in the case of the Janssen vaccine.
On the other hand, the Delta, Delta-plus and Gama-plus variants are of concern to infectologists around the world and many countries are reviewing the flexibility measures, however the WHO itself warns of the “false sense of security” due to 80% of cases of infection of the last 4 weeks are of the Delta variant.
It should also be noted that the younger population, the most prone to activities that can cause crowding, still do not have the second full dose and it is important to maintain restrictions so that the new, more lethal variants do not cause countless deaths.
