Drinking alcohol after getting a coronavirus vaccine can considerably blunt the immune action and possibly render the vaccine inadequate, according to a leading Russian researcher. “We strongly recommend refraining from alcohol for three days after each injection,” Alexander Gintsburg, head of the Gamaleya National Center of Public Health and Microbiology in Moscow, which is establishing the Sputnik V vaccine, told New Researcher
This warning doesn’t simply apply to the Sputnik V vaccine, but all covid-19 vaccines and certainly all other vaccines. “This is rather apparent,” he said.
Existing clinical literature on alcohol and the immune system shows that excess alcohol is an immunosuppressant so individuals who drink a lot are more prone to infections. “Problem drinkers have numerous issues and bad immune function is among them,” says immunologist Eleanor Riley at the University of Edinburgh, UK.

In trials, about 10 per cent of individuals don’t become immune after getting the Sputnik V vaccine and the figure is comparable for other vaccines. Whether alcohol might be a factor hasn’t been investigated.
A 2012 research study by researchers in Sweden found that low-to-moderate alcohol intake somewhat reduced the inflammatory response to a vaccine against bacterial pneumonia, but had no impact on the immune reaction. The scientists defined this level of alcohol usage as a typical intake of less than 30 grams a day, about the same as two double vodkas.
Gintsburg said that drinking 300 grams of vodka– about 12 UK procedures, which consist of an overall of about 120 grams of alcohol– reduces antibody production. One glass of champagne would be OK, he said.
Recently, Anna Popova, the head of the Russian Federal Service for Monitoring on Consumer Rights Protection and Human Wellness ( Rospotrebnadzor), triggered a controversy in Russia when she encouraged Russians to quit drinking alcohol two weeks prior to their very first vaccine shot and for a further three weeks after the second. There is a three-week space in between injections so that is a total of eight weeks on the wagon.
“Of course, we are not talking about a total restriction on alcohol during vaccination. “It is essential to understand that extreme alcohol consumption can considerably decrease resistance and for that reason minimize the efficiency of vaccination or even make it useless.
Kirill Dmitriev, CEO of the Russian Direct Mutual Fund, which is funding the Sputnik V program, states: “It uses to all vaccines, there is nothing specific about Sputnik vaccine that makes it more vulnerable to alcohol intake.”
Some people might wish to err on the side of care, says Paul Klenerman at the University of Oxford. “There’s no doubt that persistent excess alcohol has a substantial influence on numerous elements of immunity,” he says. “What isn’t clear is whether simply a small amount would have any significant effect in[real-life settings] It is plausible and you might merely be very careful and say avoid it. Various nations might wind up giving different assistance.”
New Researcher reached a volunteer on the UK arm of the trial of the vaccine being established by AstraZeneca and the University of Oxford. There was no guideline to abstain from alcohol around the time of vaccination, the volunteer stated.
A volunteer on the UK-based Imperial College London vaccine medical trial also said there was no requirement to avoid alcohol. An information sheet offered to trial participants states that people with “thought or understood present alcohol or drug reliance” can not take part in the study. It doesn’t state why.
Pfizer has said that there is no cautioning about alcohol usage related to the vaccine it has established with BioNTech. AstraZeneca, which has signed a deal to team up with the Sputnik V project, didn’t react to a request for info on alcohol and vaccination.
