Drinking alcohol before or after having the coronavirus vaccine is unlikely to impact the effectiveness of the jab, experts have said. It comes after Drink Aware issued guidance from its independent medical advisory panel warning people not to drink “at least two days before, and at least two weeks after” being vaccinated, “to ensure your immune system is at its best to respond to the vaccine and protect you”. The comments were made by Dr Fiona Sim in her capacity as chair of the advisory panel. She is also a Senior Clinical Adviser at NHS England and a visiting professor at the University of Bedfordshire. The Drink Aware guidance adds there is “little data” about the impact of alcohol on the effectiveness of the Covid-19 vaccine. But Dr Sim states: “Chronic heavy drinking reduces immune protection, and specifically for respiratory infections, which includes Covid-19. “For greatest benefit from the vaccine, it is prudent for you not to drink any alcohol for a few days before, and for at least two weeks after, you've been vaccinated.” But other experts have said this is not necessary and is not recommended in the labelling of the Pfizer or AstraZeneca jabs. “It wouldn’t affect the immune response to be honest,” Dr Gillies O'Bryan-Tear, of the Faculty of Pharmaceutical Medicine, said. “People who drink heavily are somewhat immunosuppressed… (but) it’s certainly not advice around vaccinations I am aware of.” He added that Drink Aware “must have scientific reasons” for issuing the advice, but added: “From my point of view I can’t see why they’ve recommended that”. “We would not deny the vaccination to alcoholics,” he said. “It'll still work, they still need to be protected.” Professor Gary McLean, of the School of Human Sciences at London Metropolitan University and a visiting professor at Imperial College London, said getting “hammered” directly after taking the vaccine wouldn’t be advised. But added “usual drinking within guidelines wouldn't be wouldn't be too negative” on a person’s immune system and is unlikely to impact the effectiveness of the Covid vaccine. It is also not recommended to avoid alcohol days before the seasonal flu jab, he added.
