1. Systemic reaction: The first manifestation is fever. Mild fever is 37-37.5℃, moderate fever is 37.6-38.5℃, and above 39℃ is severe fever. In addition, some babies may have headaches, dizziness, general weakness, chills, nausea, vomiting, abdominal pain, diarrhea, etc. The above reactions usually subside within 24 hours and rarely last for more than 3 days. If the fever is severe, you can take antipyretics. Generally, after the body temperature returns to normal, other symptoms will subside. If the high fever does not subside or there are other abnormalities, you should go to the hospital in time.

2. Local reactions: usually appear about 24 hours after vaccination, and the injection site may experience redness, swelling, heat and pain. Severe reactions can cause inflammation of nearby lymph nodes and lymphatic vessels. The range of swelling and nodules at the injection site is divided into mild, moderate and severe. The diameter of mild cases is less than 2.5CM, that of moderate cases is between 2.5-5CM, and that of cases exceeding 5CM is a severe reaction, which may last for several hours. If the local redness and swelling are severe, you can apply hot compress. Once in the morning and once in the evening, each time for about 5 minutes. And you should change your underwear frequently to avoid infection after ulceration. If local infection occurs, apply gentian violet.

But if the reaction is strong and lasts for a long time, you should take your baby to the hospital immediately to see a doctor.
