Each tenth resident of the Earth turned out to be immune to vaccines not only against COVID-19, but also against other diseases. This was announced in the Interview with Izvestia, the director of the Scientific Center “Vector” Rinat Maxutov.
“In the population there is always about ten percent of the population, which do not react (in terms of forming immunity) to any vaccines,” he said, noting that many factors affect the production of antibodies – from human behavior to the features of his immune Systems.
Maxutov indicated that the instructions for the “epivakororor” and other Russian vaccines state that the protective titer of antibodies and the duration of immunity after vaccination are unknown. It will be found out after the end of the post-registration studies in the middle-end of April.
The head of the “Vector” said that after any vaccine from Coronavirus there is a chance to get infected. Most often, this is due to the fact that the time required for the appearance of full-fledged immunity has passed. For example, during clinical studies at 150 volunteers over 60 years of first vaccination, 20 people got sick.
