New Crown vaccine is not recommended after drinking alcohol. The New Crown Vaccine is a heterologous protein that, when injected into the body, prevents the invasion of the New Crown Pneumonia Virus by stimulating the body to produce comprehensive antibodies. After vaccination with the New Crown vaccine, some vaccinated people may have adverse reactions, such as weakness, dizziness, diarrhea, fever, allergy and other reactions. These adverse reactions may also occur when the body is stimulated by ethanol from alcohol consumption, resulting in aggravating the discomfort of the vaccinated person. The higher concentration of alcohol in the blood may cause the body’s immunity to decline and may even affect the immunization effect of the vaccine. Therefore, alcohol should be banned three days before the new crown vaccination, and alcohol should be avoided for one week after the vaccination, paying attention to a light diet.
