A 75-year-old resident of Naberezhnye Chelny, who had a coronavirus infection, believes that he was very mistaken when he thought that COVID-19 was not dangerous. Rafik Khasanshin admits that he underestimated the insidiousness of the virus and for this reason did not respond to the doctors' call to get vaccinated. The pensioner decided to get vaccinated and recently completed a full course of vaccination.
