Mild fever, irritability and soreness at the injection site can occur after childhood vaccination and usually settle. Breathing difficulty, facial swelling, seizure, a child who is hard to wake, or rapidly worsening illness requires urgent medical help.
Is Fever Normal After a Baby or Child’s Vaccination?
Mild fever, irritability and soreness at the injection site can occur as the immune system responds. The timing and likelihood vary by vaccine, and most uncomplicated reactions improve within a short period. Check temperature with a digital thermometer, offer breastfeeds or fluids and keep clothing comfortable. Cold sponging and over-wrapping are not useful, and medicine doses must be based on the child and professional guidance.
Expected Vaccine Reactions: Soreness, Irritability and Mild Fever
A serious allergic reaction usually begins quickly and may cause breathing difficulty, facial or tongue swelling, widespread hives, collapse or unusual limpness. Vaccination staff are trained to treat immediate reactions. A first seizure, blue lips, a child who is hard to wake, persistent poor feeding, dehydration or a non-fading rash needs urgent assessment rather than being assumed to be a normal vaccine reaction.
