The healthcare provider is educating a parent about side effects of routine immunizations. Which of the following must be reported immediately?

A temperature of 102.5├âÔÇÜ├é┬░F or higher following immunization is considered an adverse reaction and should be reported immediately. This could indicate a more serious systemic response to the vaccine. Irritability, slight edema at the injection site, and local tenderness are common, mild side effects of routine immunizations and do not typically require immediate reporting. Other reactions that should be reported immediately include excessive crying for more than 3 hours, seizure activity, and the presence of tender, swollen, or reddened areas at the injection site.
