There are usually no foods that need to be avoided after receiving the vaccine. There is no clinical data to prove that consuming food after vaccination will affect the efficacy of the vaccine and cause discomfort. The nine-valent vaccine is used to prevent cervical cancer caused by HPV, mainly targeting HPV subtypes 6, 11, 16, 18, 31, 33, 45, 52 and 58. It is recommended to eat more protein-rich foods, such as marine fish, beef, soy products, milk, etc., and more vitamin-rich foods, such as kiwi, carrots, spinach, etc., after taking the vaccine. When there are uncomfortable symptoms after receiving the vaccine, please consult the doctor and take active treatment in time so as not to miss the opportunity to treat your condition.
