After vaccination, some adverse reactions may be manifested, mainly including weakness, dizziness, fever or swelling and pain of the skin at the injection site. At this time, consumption of spicy and stimulating foods may aggravate the adverse reactions and cause inflammatory reactions such as local redness, swelling, heat and pain, or cover up the real situation and cause confusion of symptoms, i.e., it is not possible to determine whether the adverse reactions are caused by the vaccine or spicy and stimulating foods, which is not conducive to the judgment of the cause, and may also affect the effect of vaccination. After vaccination, antibodies will be produced in the body, and the consumption of stimulating foods may have an effect on the production of antibodies, resulting in unsatisfactory vaccination results or even unsuccessful vaccination. After vaccination, small wounds will be left on the local skin, and consumption of irritating foods may cause inflammatory reactions and inflammation of the skin at the vaccination site. Since the vaccine contains trace amounts of pathogenic microorganisms that remove toxicity, some vaccinees may develop fever under its stimulation, and consumption of stimulating foods may aggravate the fever and may reduce the effectiveness of the vaccine. In addition, eating spicy food can also stimulate the stomach and intestines, which may cause gastrointestinal reactions, nausea, vomiting and other symptoms, and aggravate the discomfort of vaccinated patients. Therefore, try not to eat spicy food after vaccination. You should stay for half an hour after the vaccination and report any discomfort to the medical staff in time. Do not let the injection site touch water within 1 day after vaccination, and take proper rest and drink more water appropriately.
