Can I eat fried chicken after receiving the hepatitis B vaccine?

In general, it is usually not recommended to eat fried chicken after receiving the hepatitis B vaccine. The specific reasons are as follows:

Fried chicken is made by frying marinated chicken in oil and contains a high amount of saturated fatty acids. Consuming it after vaccination may interfere with the body's absorption of the vaccine components, thereby reducing the vaccine's effectiveness and lowering the success rate of antibody production. Moreover, as a deep-fried food, fried chicken is greasy and may impair gastrointestinal digestion, affect immune function, and further reduce the efficacy of hepatitis B vaccine absorption.

In daily life, apart from avoiding fried chicken after vaccination, it is also advisable to refrain from consuming spicy foods, allergenic foods ("trigger foods"), and other irritating foods to prevent interference with the vaccine's effectiveness. Additionally, after receiving the hepatitis B vaccine, individuals should remain at the vaccination site for at least 30 minutes for observation to guard against potential adverse reactions. After vaccination, it is important to maintain a light diet, avoid staying up late, get adequate rest, and keep the injection site clean and hygienic. If symptoms such as yellowing of the skin or eyes (jaundice), fatigue, or other discomforts occur, medical attention should be sought promptly to avoid delaying treatment.
