“Not a single vaccination saves 100% from infection with a viral infection ... Vaccination is done so that when an infection comes, there are already troops of immunity, ready for defense, and not formed from reserves for 5-7 days, while the infection multiplies "- quoted by RIA Novosti.

Timakov stressed that in the case of receiving a vaccine, a person will have active immunity the very next day after infection with COVID-19. 

“Thus, the infectious process can begin, but there will be no complications, there will be no deaths, there will be no complications on organs, there will be no hospitalization, there will be no mechanical ventilation, and the person will carry the infection in a mild asymptomatic form,” the infectious disease specialist explained.
