Question

My baby developed a slight fever about four days after vaccination, around 38 degrees. Is this related to the vaccination?

Answer

If your baby experiences a slight fever about four days after receiving the vaccine, it is generally not likely to be a direct side effect of the vaccine. Common side effects of vaccines usually appear within 48 to 72 hours after administration. Typically, viral infections are more common causes of fever. It is recommended to monitor the temperature at home, and if the temperature exceeds 38.5 degrees, administer fever-reducing medication. At the same time, observe for any changes in other symptoms. If the condition does not improve, it is advisable to bring your baby to a pediatric clinic for examination as soon as possible.
