Question
The child is 6 months old and received the second dose of the oral polio vaccine while also being administered the quadrivalent vaccine. That afternoon, the child began to have a fever, accompanied by symptoms such as coughing, runny nose, sore throat, and reached a temperature of 39 degrees on the third day. After consultation and taking cold medicine, the fever subsided, but it rose again in the afternoon and evening, reaching a maximum of 37.5 degrees. The parents are worried whether the child might have been infected with polio.
Answer
Children should follow the vaccination schedule to regularly receive vaccines to prevent the occurrence of infectious diseases. By about one year old, children need to receive vaccines almost every month. Some children may experience inflammation at the injection site or fever after vaccination due to the vaccine acting as an antigen to stimulate an immune response and prompt the body to produce antibodies. Fever may be part of this immune process.
