A 18-month-old baby has a fever after receiving the DTP and MMR vaccination.

Patient's question:

The child got vaccinated today and developed a fever indirectly after returning home. They have a slight cough and a slightly inflamed throat. They received a fever-reducing shot in the middle, which has already lowered the fever. Now, they have started developing a high fever again, reaching 38 degrees Celsius. Could you please ask the doctor if there is any issue?
Previous treatment and effectiveness: Went to the pet hospital to receive a fever-reducing shot and an anti-inflammatory shot.
What assistance is needed: I would like to ask the doctor if these symptoms could indicate any problems or if they might lead to other diseases.

Doctor's answer:

This situation may be a vaccine reaction caused by anesthesia. If the temperature does not exceed 38.5 degrees, it is generally not recommended to use fever-reducing medication. You can let the baby drink more hot water and closely monitor the situation.
Suggestions: Vaccine reactions usually occur within three days after anesthesia. If the temperature is high, you can use ibuprofen to reduce fever. If there is inflammation in the throat, you can use medications such as Shuanghuanglian, Qingkailing, or Chaihuang Granules for treatment. Avoid using antibiotics for the time being to prevent them from affecting the vaccine's preventive effects.
