Experts evaluate protection from immunizers after new variants discovered
The effectiveness of vaccines about variants of coronavirus should be presented this week. The coordinator of the Corona-ômica Network, of the Ministry of Science and Technology, Fernando Spilki, estimates that so far the analyzes show more transmissibility of the virus, but it is still not possible to talk about a greater severity of the disease. “I would say that we will be able to say ‘look at the vaccine, she may or may not face this or that difficulty’ and how we can go ahead to win, in the event of this type of challenge that stands in the way,” he said. Fernando Spilki, evaluates the possibility of updating vaccines on coronavirus variants. “In the meantime, most likely, we will have clinical protection from vaccination. These corrections are going to be important for herd immunity, for less circulation of the virus. But the vaccine must protect clinically over time despite some differences. So it is important to keep intensifying the vaccine program and if there is a need for correction, it is not out of this world, it is possible to do so. ”
The moment is delicate because the variants are identified as responsible for the explosion of cases in Manaus, Rio Grande do Norte, Rio de Janeiro and cities like Araraquara in the interior of São Paulo. Experts point out that the new strain will be in all Brazilian states. The Ministry of Health confirmed the state of alert after the circulation of two variants in Rio Grande do Norte, P.1, identified in Manaus, and P.2, registered in Rio de Janeiro. At the beginning of the year, the state received 50 patients transferred from Manaus. New strains to occupy beds above 85% in public hospitals in Rio Grande do Norte. The immunologist, Ana Carolina Barreto, regrets the lack of vaccines to contain the spread of the disease in Brazil. “Unfortunately, we are going to see activity restrictions in some places. Perhaps it is the only measure to control the spread of infections and the spread of variants a little, ”he said. A report published this weekend by a network of scientists that monitors the virus genome warns that the mutations recorded in Manaus and Rio de Janeiro have been circulating since December in Natal, Rio Grande do Norte, and in João Pessoa and two more cities in Paraíba.
