Drinking alcohol before and after the vaccination may affect the body and the vaccination effect, therefore, it is not recommended to drink alcohol 3 days before the vaccination and 1 week after the vaccination. If you drink alcohol before the vaccination, the body may not fully metabolize the alcohol in your body if the time of drinking is close to the time of vaccination, which may lead to incomplete absorption of the vaccine and affect antibody production and weaken the defense effect. After the New Crown vaccine, the body may experience various adverse reactions to the vaccine, such as redness and swelling at the needle holes, and adverse reactions such as dizziness, nausea, vomiting, arm pain and weakness, etc. Drinking alcohol at this time may aggravate these adverse reactions. After drinking alcohol, vaccine recipients may themselves experience dizziness, vomiting and other post-vaccination reactions due to the effect of alcohol, which may be easily confused with adverse reactions caused by the New Crown vaccine at this time and may be misjudged. Before receiving the New Crown vaccine, it is important to fully understand the precautions and contraindicated groups for vaccination, and try not to have an empty stomach to prevent dizziness. After the New Crown vaccination, care should be taken not to drink alcohol, stay up late, or engage in strenuous activities, etc. Eat a light diet and avoid eating too much spicy and stimulating food to avoid affecting the body’s recovery.
