There is usually no need to emphasize specifically what not to eat after a booster hepatitis B vaccination. After receiving the booster hepatitis B vaccination, it is best to eat less greasy, fried foods, and light, easily digestible foods. It is also best to avoid spicy and irritating foods such as chili peppers, green onions, garlic, and ginger, which can irritate the gastrointestinal tract. Try not to eat allergic foods, such as seafood, tropical fruits, mango and durian. Avoid drinking alcohol, strong tea or coffee and other stimulating beverages. Drinking alcohol can lower immunity and affect the production of antibodies. After taking the hepatitis B booster shot, observe for half an hour and then leave if there is no discomfort, and inform the doctor promptly if there is any discomfort.
