The new coronavirus vaccine that has been marketed for use has clearly defined the contraindications to vaccination and vaccination precautions, generally after vaccination, need to stay for 30 minutes; to keep the local skin of the vaccination clean, avoid scratching the vaccination site; if a suspected adverse reaction occurs, report to the vaccination unit, and seek medical attention promptly when needed. However, there are still many people who have questions about their habits after vaccination, such as whether they can drink alcohol, eat seafood, and whether there are any other contraindications. What are the dietary taboos after vaccination? But in fact, there is no clear dietary contraindication after vaccination, so there is no need to deliberately change the original diet, but it is recommended that within 2-3 days after vaccination, try not to eat spicy and stimulating or easy to cause an allergic reaction to the food, because during this time, some of the vaccinees may have redness and swelling at the site of the vaccination, hard nodules, generalized fever, malaise, headache, and even nausea, diarrhea and other symptoms appear, so try to be as simple as possible, light diet to make it easy to distinguish whether these symptoms are vaccine-induced adverse reactions or diet-induced discomfort reactions. Also, be aware that light overeating is not advisable. Can I drink alcohol after vaccination? There is no clear requirement on whether you can drink alcohol after vaccination, but it is recommended that vaccinees try not to drink for 2-3 days after vaccination. This is because during this time, some of the vaccinated people may have adverse reactions, and drinking alcohol may lead to worsening of the adverse reactions, so it is not recommended to drink alcohol. Secondly, drinking alcohol may lead to a decrease in the body’s immune function, which will have a certain effect on the antibody. Although there is no clear clinical research to prove that alcohol affects the protective effectiveness of the vaccine, in order to avoid accidents, the vaccinated person should try not to drink alcohol for a short period of time, especially higher degree white wine or shochu (burnt wine). Can I eat seafood after vaccination? As to whether you can eat seafood after receiving the New Crown vaccine, it also varies from person to person, and everyone’s constitution is different, but in general, it is not recommended to eat it within a week after vaccination. Because after vaccination some vaccinated people will have some transient adverse reactions, such as nausea, abdominal pain, diarrhea, etc., and most of the seafood is cold food, which itself may cause gastrointestinal discomfort, abdominal pain, diarrhea, vomiting and other uncomfortable reactions, so in order to clarify the reason for the emergence of the body’s reaction, it is recommended that we wait for the adverse reactions to disappear completely before eating. The degree of adverse reactions and symptoms of vaccines vary from person to person. If the vaccinee suspects that the uncomfortable symptoms may be related to the new coronavirus vaccination, he/she can report it to the vaccination unit, or to the county-level disease control agency or the adverse drug reaction monitoring agency where the vaccination unit is located. If the public is unable to determine whether the symptoms are related to vaccination, they may consult the vaccination unit.
