The actual effectiveness of the Pfizer-BioNTech coronavirus vaccine is 98% according to the results of its use.
Natalia Vynohrad, an epidemiologist at Ukraine’s Ministry of Health, said this at a press conference at Ukrinform.
"In the beginning, the vaccine was 95% effective; the real effectiveness in the countries that use it totals 98%. Thus, the rate in higher, but it is typical for other vaccines as well," said Vynohrad.
The epidemiologist stressed that this vaccine uses a new technology. Thus, unlike other vaccines, the Pfizer-BioNTech vaccine does not contain antigen that triggers an immune response. "This is genetic information that will trigger the synthesis of antigen in a vaccinated person, to which antibodies are formed," Vynohrad explained.
According to her, the Pfizer-BioNTech vaccine is able to respond quickly to mutations that occur in the coronavirus. She also said that the adverse events that occurred after the use of this vaccine did not differ from those specified by the manufacturer.
