How to handle fever after vaccination in a ten-month-old baby

Patient's question:

Yesterday, I got the meningitis vaccine. This afternoon, after a good night's sleep, I started having a high fever, 38.7 degrees. I'm doing well mentally, eating dinner normally, but I've dry vomited twice, in small amounts.
Past treatment history and effectiveness: No treatment.
What kind of help is needed: Should I take medication to reduce the fever? What should I do?

Doctor's answer:

A ten-month-old baby got the meningococcal vaccine yesterday. Today in the afternoon, after a good nap, they started having a high fever of 38.7°C. They are in good spirits, eating dinner normally, and have vomited twice, but the amount was small. It is considered that the fever is caused by the vaccine, which is a normal phenomenon, and many babies react this way.
Advice: Since the temperature is currently below 38.5°C, you can give fever-reducing medication, drink more hot water, and pay attention to keeping warm. First, observe carefully and consider giving some children's cold medicine granules. Generally, fever caused by vaccinations usually improves on its own within 2-3 days. There is no need for special treatment—just treat the symptoms, and don’t worry.
The above is the advice for the question "What should I do if a ten-month-old baby has a high fever after vaccination?" I hope it helps you. Wishing you good health!
