Is fever caused by vaccination?

Patient's question:

My baby is 3 years old. Last week, on the 18th, I took him to get the encephalitis vaccine (he missed it when he was 2). After that, everything seemed fine. On the 21st, when he was sleeping at night, he felt unwell. At around 5:00 AM, he had a high fever of 37.9 degrees. Later, on the 22nd, his fever reached 39.1 degrees in the afternoon. After taking fever-reducing medicine, the doctor drew blood and said it was a viral infection, but added, "From the report, if he hadn’t had a high fever, we could have believed it was normal." At around 3:00 AM that night, his fever rose again to 39 degrees, and he took fever-reducing medicine. I wonder if this is a side effect of the vaccine? I forgot to mention this to the doctor when I was careless. The weather was cloudy with snow from the 18th to the 21st, while it had been hot before.
Medical history and treatment effectiveness:
The doctor prescribed Ribavirin Granules and Antiviral Granules, but even while taking them, his fever persisted and came and went.
Help needed regarding fever-reducing medicine:
1. How can the high fever be linked to the vaccine?
2. How many times can fever-reducing medicine be taken consecutively?
3. Is it better to take fever-reducing medicine and antiviral medicine for a few days, or is it better to have one intravenous drip with fewer side effects?
Thank you.

Doctor's answer:

It is recommended that you first go to the hospital for a check-up to see if it is caused by the anesthesia vaccine, and seek treatment under the guidance of a doctor. Medical advice: High fever does not necessarily mean it is caused by vaccination; it could also be due to inflammation. If the fever is caused by vaccination, it will subside within 72 hours. For such fever, you can use physical cooling methods. It is recommended that you take your child to the hospital promptly for a thorough examination and treatment. I hope this can help you. The above is advice on the question "Is the high fever caused by vaccination?", and I hope it is helpful to you. Wishing you good health!
