You can eat spicy food in moderation before vaccination, but you should not eat too much, so as not to stimulate the gastrointestinal tract with excessive chili peppers, which may cause adverse reactions before vaccination and thus affect the normal vaccination. For people who are allergy-prone, avoid eating spicy food before vaccination. If the vaccinated person often eats spicy food in daily life and has no discomfort, he or she can maintain normal eating habits before vaccination, but pay attention to control the amount of food eaten and do not eat too much or too spicy. After eating spicy food, observe whether there is any stomach discomfort, and consult your doctor if you need to delay the vaccination if you have any discomfort to avoid adverse reactions. Before vaccination, ensure sufficient sleep and try not to have vaccination on an empty stomach. Reduce the intake of coffee and strong tea, and avoid drinking alcohol. Do not take a shower for 1 day after vaccination to avoid getting water on the needle holes, do not recommend eating spicy food for 1 week, and avoid smoking and drinking alcohol.
