After taking the second dose of Pfizer-Bioentech corona vaccine, the human body develops corona-resistant proteins and the vaccine has the highest efficacy for the first six months. Doses of this tick can develop resistance in the human body against conventional coronavirus and any type of this virus.
Authorities at Pfizer and Bioentech said in a statement on Thursday that the results were obtained at the end of a third-phase medical trial of the Pfizer-Bioentech vaccine.
But vaccine experts in the United States say the vaccine lasts longer, not six months. This is because the vaccine plays a role in the formation of special cells in the body within a few weeks of receiving the vaccine.
The corona vaccine was jointly developed by US pharmaceutical company Pfizer and German biotechnology company Bioentech in November last year. The United States and Europe also approved the vaccine for emergency use in the first week of December.
Of the 47,000 volunteers who took part in the trial, 600 were from South Africa and six of the 928 coronaviruses were infected with the South African virus.
According to international biologists, physicians and scientists, the South African strain of the coronavirus, or B1.351, is the most dangerous strain of SARS-Cove-2 or coronavirus ever identified.
The US Centers for Disease Control (CDC) has already stated that the vaccine is 100 per cent effective in critically ill patients with coronavirus, the statement said. Another regulator, the US Food and Drug Administration (FDA), ruled that the vaccine was 95.3% effective in critically ill patients.
Albert Borla, chairman and CEO of Pfizer, said in a statement: “The results of the third phase of the medical trial are very promising. It boosted our confidence. ”
“Within a few weeks of taking two doses of the vaccine, the human body begins to develop corona-resistant proteins,” he said. After six months, the protein reaches its maximum active level.
‘But in the meanwhile, a special type of cell called B cell grows in the human body due to the effect of vaccine. The function of these cells is to produce corona-resistant proteins in the human body. For this reason, if for some reason the effectiveness of the tick dose protein decreases after six months, there is no problem. B cell fills that gap. ‘
