The Russian vaccine against coronavirus allows the formation of long-term immunity, which is likely to last up to two years, according to the press service of the Ministry of Health.
“The double scheme of vaccine administration allows the formation of long-term immunity. The experience of using vector vaccines (with a double scheme of administration) shows that immunity lasts up to two years,” the message says.
It specifies that the drug registered on August 11, Gam-COVID-Vac, is a vector two-component vaccine based on the human adenovirus.
“The vaccine has passed all the necessary safety and efficacy tests on several species of animals (rodents and primates), and later the vaccine was tested on two groups of volunteers (38 people each). The vaccine does not contain the components of the COVID-19 virus,” the message explains.
