It is recommended that you try not to get the new crown vaccine if you had alcohol 10 hours ago. It is recommended that you consider going to a community vaccination site or CDC for vaccination after 3 days. Do not drink alcohol for a few days before or after the New Crown vaccination because alcohol may affect the vaccination effect, and the adverse reactions from drinking alcohol may confuse the adverse reactions of the vaccine and cause misdiagnosis. alcohol consumed 10 hours before is not fully metabolized, and it generally takes about 48 hours for alcohol to be fully metabolized from the body, and the larger the amount of alcohol consumed and the higher the alcohol concentration, the longer it will take for alcohol to be fully metabolized in the body. In addition, the time of metabolism is also related to the concentration of alcohol, the amount of alcohol consumed and the function of the liver. Alcohol metabolism is also related to the activity of enzymes required for alcohol metabolism such as ethanol dehydrogenase and acetaldehyde dehydrogenase in the human body, and there are individual differences in the strength of the enzymes, so there are certain differences in the time for alcohol metabolism. The process of alcohol metabolism will have a certain effect on the human immune system, and if the vaccination is given at this time, it may affect the vaccination effect. In addition, if there is a certain amount of alcohol in the body before administering the new crown vaccine, alcohol itself can promote blood circulation, lead to capillary dilation and increase vascular permeability, which may increase blood exudation from the injection site, and local redness, swelling, hard nodes and pain may easily appear, aggravating the adverse reactions after vaccination. In case of heavy alcohol consumption, adverse reactions such as dizziness, headache, nausea and regurgitation may occur, and the above adverse reactions may also occur after the New Crown vaccine, which may lead to the masking of the adverse reactions produced by the New Crown vaccine at this time and may easily cause misjudgment or misdiagnosis. It is recommended to hold off on the New Crown vaccine and make sure that the alcohol in your body is completely metabolized and that your body is in good condition before receiving the New Crown vaccine. However, if you drank alcohol 10 hours ago, but the amount of alcohol consumed was very small and it is not possible to postpone the vaccination, it is recommended to ask your local vaccination officer if the vaccination is possible. If you receive the New Crown vaccine, stay for 30 minutes as required, watch for adverse reactions, and report any abnormalities to medical personnel in a timely manner. It is also important to observe the occurrence of adverse reactions for 2-3 days after vaccination, and at the same time, pay attention to more rest, drink more water, avoid drinking alcohol again, and avoid eating spicy and stimulating foods.
