Russia is in an uproar after a health official said people shouldn't drink alcohol two weeks before and six weeks after getting the COVID-19 vaccine.
According to Business Insider, there's no evidence that alcohol consumption is linked to Sputnik V's vaccine efficacy--or any other vaccine's efficacy.
However, booze has been found to weaken the immune system. There is a waiting period of 21 days between the first and second Sputnik V shots.
Having a strong immune system is especially important during a pandemic, so it may be wise to cut back on alcohol for that reason.
The Russians have yet to release their complete, peer-reviewed data from phase 1 and 2 trials of Sputnik V, creating an air of secrecy around the vaccine.
