The President of Argentina, Alberto Fernández, tested positive for covid-19 even after receiving the two doses of the Russian Sputnik V vaccine, as announced this Saturday (3). With mild symptoms, the politician even registered 37.7 degrees of fever and headache.
According to infectologist Renato Kfouri, director of SBIm (Brazilian Society of Immunizations) and member of the Technical Advisory Committee of the National Immunization Program (PNI) of the Ministry of Health, this is possible because none of the immunizers tested against the coronavirus is 100% effective.
In the case of Sputnik V, developed by the Gamaleya Institute in Russia, the proven effectiveness for the prevention of covid-19 is 91.6%. Therefore, according to Kfouri, immunization does not dispense the use of masks.
“There are at least three reasons that justify the use of the mask after the second dose: the vaccines are not 100% effective, so it is still possible to contract the disease. Even if it is not serious, it can cause malaise; there are no unequivocal demonstrations of that vaccines are capable of preventing transmission, so the vaccinated individual may not get sick, but will transmit it to others, ”he says.
During the phase 3 tests of the Sputnik V clinical studies, a stage in which the effectiveness of the immunizer is assessed, there were 16 symptomatic cases of covid-19 among people who received the vaccine, according to the Gamaleya Institute.
The Argentine Ministry of Health reported that the president is among less than 0.2% of those vaccinated in the country who have contracted covid-19. Minister Carla Vizzotti said the data is being analyzed by the government.
Fernández, who turned 62 last Friday (2), received the first dose of Sputnik V on January 21 and was inoculated with the second dose on February 11, according to the presidential office.
“What my doctors tell me is that the vaccine has generated a significant amount of antibodies so that I am not experiencing it now as a 62-year-old who is infected,” he explained.
“If it weren’t for the vaccine, I would obviously be in very bad shape, which is how the virus attacks a person my age,” he added.
According to the vaccination panel at La Nación, one of the main Argentine newspapers, so far 3,495,125 (7.7%) people have received the first dose of the vaccine and 683,771 (1.5%) have also applied the second dose of the immunizer against covid-19. In all, the neighboring country had 2,373,153 infected by the disease, having lost 56,023 lives.
Sputnik V no Brasil
The Chemical Union, a pharmaceutical that represents the Russian vaccine in Brazil, has already sent two requests to Anvisa (National Health Surveillance Agency) for the release of the emergency use of the immunizer, the last of which was sent on March 26.
In a note released last Thursday (1st), Anvisa stated that the company is still did not send the complete documentation for the analysis of the second request, which resulted in the suspension of the response period regarding the authorization.
The first request was rejected by the agency on January 16, because União Química did not send the necessary documents for the continuity of the analysis.
