What should I do if my baby has a fever at night after getting vaccinated?

Patient's question:

Morning, I got the Japanese encephalitis and leprosy shots, and by the afternoon, I started having a runny nose. In the evening, I had a fever of 38 degrees Celsius, with cold hands and feet, but my forehead wasn't too hot, though my face felt very hot. About my past treatment and its effects, and the help I need: Could this be a cold or caused by the vaccination? Can I take medicine for both?

Doctor's answer:

The baby's condition should be that individuals with a weakened or immature immune system, such as children, cannot tolerate attenuated live vaccines, leading to a recurrence of hypersensitivity reactions. As long as the baby has a good appetite, is in good spirits, and does not refuse milk, there is no need for special measures—just let the baby drink more hot water. If the temperature is below 38.5°C and is accompanied by symptoms such as irritability, crying, and refusal to feed, it is important to seek follow-up medical attention promptly.
