People receiving coronavirus vaccines should limit their alcohol intake, eat less processed food and ensure they get plenty of sleep, according to Margaret Harris, of the World Health Organization (WHO).

"That's our recommendation, basically, look after your health," she told CGTN Europe, noting that the WHO did not have specific guidance over exactly what measures should be followed in what time frame around getting a vaccine.

Russia's consumer safety watchdog this week urged the public to avoid drinking alcohol for around two months around the time they are given the Sputnik V jab.

Speaking from the WHO's base in Geneva, Harris said she couldn't comment on the specifics around the Russian case but confirmed that in general it is recommended to take a range of actions to strengthen the body's immune system whenever receiving vaccinations. Other steps could include consuming more fresh food, stopping smoking and taking part in exercise, she added.
