Alcohol is not recommended the week before or after the third dose of the new coronavirus vaccine. The third dose of the new coronary vaccine is usually the third dose of the new inactivated coronary virus vaccine booster or the recombinant subunit vaccine. Regardless of the type of vaccination, alcohol consumption before and after vaccination may induce or aggravate the body’s adverse reactions to the vaccine, such as fever, dizziness, nausea, and in severe cases, rash, difficulty in breathing, and drop in blood pressure. In addition, alcohol may affect the body’s immune function and cause a decrease in the immunization effect of the vaccine. Therefore, alcohol should be avoided before and after the booster shot of the new coronavirus vaccine to affect the effect of the vaccine or to induce adverse reactions. In addition, good dietary habits should be practiced, avoiding spicy and irritating foods, so that the body can better absorb the vaccine.
