What should I do if my baby has a fever of 39°C after receiving the DTP vaccine?

When a baby has a fever of 39°C after receiving the DTP vaccine, it generally refers to a post-vaccination fever. A fever of 39°C following the DTP vaccination in infants can usually be managed through follow-up observation, physical treatments, or medication.

1. Follow-up Observation

A fever of 39°C after the DTP vaccine is typically a normal vaccine reaction. If the baby does not have other physical discomforts, body temperature usually returns to normal gradually within 24 hours. Immediate treatment may not be necessary. Instead, closely monitor the baby's mental state and encourage drinking more warm water to promote metabolism.

2. Physical Treatment

If the baby remains in good spirits without significant discomfort, you may apply cooling patches or use a warm towel to wipe areas such as palms, soles, armpits, and groin to help dissipate heat and reduce body temperature.

3. Medication

If the above methods are ineffective and the baby’s fever of 39°C persists, especially if accompanied by lethargy or other symptoms, it is recommended to use antipyretic medications such as sustained-release acetaminophen tablets, sustained-release ibuprofen tablets, or ibuprofen granules under medical guidance.

If the fever remains for more than three days after the DTP vaccination, prompt medical consultation is advised, and treatment should be followed as directed by a physician.
