Patient's question:
At 10:00 in the morning, I ate the polio oral vaccine. At 1:00 in the afternoon, I developed a high fever of 39.2°C. I gave him ibuprofen suspension, and after sweating, the fever subsided. By 6:00 in the evening, the fever returned to 38.8°C, and I gave him the same medicine again, but he didn't sweat. The baby had a cold with a runny nose and a slight cough a week ago, but he didn't have a fever. It has been three or four days since he recovered, and only then did I give him the vaccine. What could have caused the fever? Does the fever-reducing medicine and the vaccine still have an effect?Doctor's answer:
After the child ate the sugar, they developed a fever again, which should be an adverse reaction to the vaccine.1. Symptomatic treatment with fever-reducing medication is available. This will absolutely not interfere with the vaccine's efficacy.
2. Do not use antiviral medication to prevent interference with the vaccine's efficacy.
3. Let the child drink more water to help lower their temperature.
4. If the temperature is above 38.5°C, symptomatic treatment with fever-reducing medication can be used. If the temperature is below 38.5°C, frequent warm water bathing can help lower the temperature, or a fever-reducing patch can be applied to the forehead.
5. In the future, vaccination must wait until the cold has completely recovered, and at least one week should pass before vaccination.
