Eating spicy food is not recommended for rabies vaccination, which may cause fever, abdominal pain and other discomforts indistinguishable from vaccine-induced adverse reactions. First of all, eating spicy food after rabies vaccination will not affect the efficacy of the rabies vaccine. After entering the body, the rabies vaccine will stimulate the immune system to produce an immune response, and ultimately produce antibodies against the rabies virus in order to achieve preventive effects. In addition, eating spicy food will not affect the efficiency of the immune system in producing anti-rabies antibodies. Adverse reactions such as redness, swelling and pain at the site of vaccination, gastrointestinal discomfort such as abdominal pain, bloating, vomiting and diarrhea may occur after rabies vaccination. It is difficult to differentiate between the fever and abdominal pain that may be induced by eating spicy food and the adverse reactions caused by the vaccine. In order to avoid the above situation, it is recommended to eat less spicy or not spicy, and at the same time should eat less seafood and other allergy-prone food.
