Does a 1-month-old baby's vaccine cause fever?

Vaccines given to a 1-month-old (usually the 2nd dose of Hepatitis B) can cause a mild fever in some babies. This is a normal response of the immune system to the vaccine. Fever typically appears within 24-48 hours after vaccination, does not exceed 38°C, and passes on its own within 1-2 days. Besides fever, you may see fussiness, loss of appetite, or redness at the injection site. If your baby's fever is 38°C or higher, I recommend not giving medication without consulting your pediatrician. Frequent breastfeeding (or slightly more frequent formula feeds if bottle-feeding) and light clothing after vaccination can help ease the fever. However, if fever lasts longer than 3 days, if your baby seems very lethargic and unresponsive, or if there are seizures, seek medical attention immediately.
