After the completion of the vaccination of the vaccines currently on the market, the dietary considerations are relatively similar, and usually require avoidance of spicy and stimulating foods, cold foods, and allergy-prone foods: 1. Avoid spicy and stimulating foods: such as chili peppers, garlic, scallions, leeks, mustard, various kinds of alcohol, etc. Spicy and stimulating foods can easily stimulate the injection site, causing local vascular exudation manifested as redness, swelling, hard nodules, pain and itching. Increase the chance of adverse reactions; 2. Avoid cold food: such as ice cream, ice-cream, cold drinks, etc. Cold stimulation can easily lead to gastrointestinal dysfunction and symptoms of abdominal pain and diarrhea. Some patients will have gastrointestinal symptoms after vaccination, manifesting as diarrhea, and the consumption of cold food at this time may aggravate the adverse reactions after vaccination; 3, avoid allergy-prone food: such as eggs, beef, mutton, seafood, etc., the inoculation site will be red, swollen and itchy after vaccination, and allergy is likely to occur if allergy-prone food is consumed, especially for allergic people; 4, avoid strong tea, coffee and wine: strong tea and coffee are not suitable for vaccination. Coffee and wine: strong tea and coffee can easily excite people, which is not conducive to sleep and affects the immunity of the body, while wine may affect the effect of the vaccine. In addition, it is not advisable to take anti-viral, anti-bacterial or anticoagulant drugs after vaccination, and if there are chronic diseases or other diseases that require medication, it is necessary to consult the doctor whether the medication can be continued after vaccination.
