MOSCOW, April 30. /TASS/. Immunity to the novel coronavirus infection after vaccination lasts for at least ten to twelve months, Anna Popova, chief of Russia’s sanitary watchdog, said on Friday.

"As for Covid-19, it is necessary to get vaccinated right now. We see already today that immunity after vaccination lasts quite a long time - from ten months to a year. We see that immunity is quite lasting, so, it is necessary to get inoculated now and the immunity will last for the next epidemic season," she said in an interview with the Rossiya-24 television channel.

According to Popova, no serious side effects after vaccination have been recorded. "Some feel slight pain around the injection site but what I mean to say is that we are inoculated with vitamins, we also fell certain discomfort around the injection site," she added.
