After a long year and a lot of anticipation, getting the vaccine can be cause for celebration, which for some might mean pouring a drink and toasting to their new immunity. But can alcohol interfere with your immune response?
The short answer is that it depends on how much you drink.
There is no evidence that having a drink or two can render any of the current Covid vaccines less effective. Some studies have even found that over the longer term, small or moderate amounts of alcohol might actually benefit the immune system by reducing inflammation.
Heavy alcohol consumption, on the other hand, particularly over the long term, can suppress the immune system and potentially interfere with your vaccine response, experts say. Since it can take weeks after a Covid shot for the body to generate protective levels of antibodies against the novel coronavirus, anything that interferes with the immune response would be cause for concern.
