It is not about all vaccines, but only about Sputnik V. It is learned that Russian officials have warned citizens to avoid alcohol for two months, after applying the Sputnik V vaccine.

According to experts, a warning against alcohol consumption, which was recently issued in Russia, is a general measure to boost immunity rather than as a specific contraindication or interaction with the vaccine.

Those receiving Russia's Sputnik V vaccine should stop consuming alcohol for nearly two months before and after immunization, the head of Russia's consumer safety watchdog said on Tuesday.

Smoking, before and after vaccination, is also not a good idea according to many health experts. This is because tobacco smoke irritates the lungs and tilts the immune responses.

The warning came from Russian Deputy Prime Minister Tatiana Golikova, who said in an interview that Russians would have to comply with additional precautions during the 42 days for the Sputnik V vaccine to become effective.

"Russians will have to refrain from frequenting crowded environments, wearing face masks, using disinfectants, minimizing contact and not consuming alcohol or immunosuppressive drugs," Golikova told the media.
