After receiving the 13-valent Pneumococcal Vaccine, you should pay attention to a light diet and do not touch water at the injection site for 1 day. 1. Light diet: eat less spicy and stimulating food, such as chili peppers and mustard. Prohibit drinking alcohol, tea, etc., because the reactions caused by spicy and stimulating foods, alcohol and tea may be difficult to distinguish from the adverse reactions caused by the vaccine, thus affecting the assessment of the safety of the vaccine. So you need to focus on light, easy-to-digest food, eat more fruits and vegetables, and drink more water. 2. Touching water at the needle opening within 1 day may cause infection at the needle opening and affect the healing. Adverse reactions such as fever, dizziness, nausea and vomiting may occur after receiving the 13-valent domestic pneumonia vaccine, which are usually mild and will be relieved on their own in about 3 days. If the reaction is more severe or persists unrelieved, you should go to the hospital immediately to avoid delaying the treatment.
