The next day after drinking at night, it is not recommended to take the vaccine because the vaccine may cause or aggravate adverse reactions to the vaccine after drinking. Since the possible adverse reactions to the vaccine are similar to the symptoms that some people experience after drinking alcohol, there is a certain risk of misdiagnosis and delayed treatment. The metabolism of alcohol by the body may also hinder the absorption of the vaccine drug by the body, thus affecting the role of the vaccine: 1. reduction of active ingredients: some components of the vaccine may combine with alcohol after drinking, and the active ingredients that work in the body may be reduced, thus affecting the efficacy of the new crown vaccine; 2. aggravation of discomfort symptoms: the new crown vaccine is a process to stimulate the body to produce antibodies, and the new crown vaccine may cause discomfort. If you drink alcohol at this time, the alcohol may affect the body and aggravate the symptoms of discomfort; 3. Misdiagnosis: If you drink alcohol the day before, the body usually needs some time to metabolize the alcohol in the body, and if the alcohol is not completely metabolized, you may experience persistent foggy consciousness, dizziness, etc. If you take the vaccine the next day, the stimulated body may also experience fever and flushing. Symptoms such as fever, flushing, nausea and headache may occur. Since the symptoms of these two conditions may be confused, it may be difficult for doctors to determine the specific cause of the disease, which may easily lead to misdiagnosis, etc. In addition, it is recommended to avoid drinking alcohol before and about 1 week after the vaccination, and to pay attention to a light diet, mainly high protein and easily digestible foods, and to avoid stimulating drinks such as coffee, strong tea, or foods such as chili and seafood.
