Russian officials are warning citizens to avoid alcohol for two months after receiving the country’s COVID-19 vaccine — tough-to-swallow news for one of the world’s heaviest drinking countries.

The warning came from Russian Deputy Prime Minister Tatiana Golikova, who said in an interview that Russians will have to observe extra precautions during the 42 days it takes for the Sputnik V coronavirus vaccine to become effective.

“[Russians] will have to refrain from visiting crowded places, wear face masks, use sanitizers, minimize contacts and refrain from drinking alcohol or taking immunosuppressant drugs,” Golikova told TASS News Agency.
