Patient's question:
The child is 6 months old and has received the second dose of polio oral drops. At the same time, they received the quadrivalent vaccine. In the afternoon of the same day, they started to have a fever, cough, runny nose, and sore throat. On the third day, the fever reached 39°C. After visiting a doctor, they took cold medicine to reduce the fever. In the afternoon and evening, they had repeated fever spikes, with the highest temperature reaching 37.5°C. Could they have been infected with polio?Doctor's answer:
After a child is born, they must follow the automatic immunization vaccination schedule for vaccines. The vaccination should be administered in a standardized manner, primarily to prevent the recurrence of many infectious diseases.After a child is born, within the first year of life, they usually need to receive vaccinations almost every month. During the vaccination period, some children may experience certain reactions, such as fever after receiving the vaccine. Some children may also exhibit local inflammatory reactions at the injection site. This is because most vaccines act as antigens in the body through an autoimmune response, triggering the production of antibodies, which may lead to a fever in children.
