Drinking alcohol after receiving rabies vaccine may make the rabies vaccine ineffective and affect its preventive effect. The rabies vaccine is a live bacteriological preparation, which is produced by removing the toxicity of the rabies bacteria while retaining its activity. Alcohol kills the germs and can kill the rabies vaccine activity inside the body, which can lead to its failure to stimulate the body to produce antibodies. In addition, alcohol is an immunosuppressant that inhibits the body from producing antibodies, which can make the rabies vaccine ineffective. Therefore, it is generally important to avoid alcohol, spicy and stimulating food and strong tea after rabies vaccination, as these can affect the preventive effect of the vaccine.
