You can eat fried chicken after vaccination, but it is recommended to eat it sparingly. Fried chicken is a greasy food, which may cause indigestion such as abdominal distension and diarrhea. After vaccination, some people may have symptoms such as redness and swelling of wounds, body fatigue, fever, dizziness, or nausea, diarrhea, loss of appetite, etc. At this time, if you eat a lot of fried chicken and other greasy food, it may aggravate the gastrointestinal discomfort, so it is recommended to eat less. If there is no dizziness, vomiting, fever and other uncomfortable symptoms, you can leave the observation room, and if there is any discomfort, go to the medical staff to ask about the situation and conduct examination and treatment in time; 2. At the same time, do not drink alcohol within one week after the vaccination, because the body itself will produce fever after drinking, which may be confused with the adverse reaction after the vaccination and is not easy to distinguish. 4. Avoid touching water: avoid touching water to the wound within 3 days after the vaccination, because the wound may still be red, swollen or not completely healed, and if it touches water, it will easily lead to wound infection.
