POOJA KOTHARIMom of a 8 yr 5 m old boy4 months agoA. After vaccination, it is common for a 1.5-month-old baby to have a mild fever, usually due to the body's normal immune response. The fever typically:
Starts within 24 hours of the vaccine. Lasts for 1 to 2 days (sometimes up to 3 days, but rarely more).
Other symptoms might include irritability, slight swelling or pain at the injection site, and reduced appetite.
What you can do:
Give paracetamol drops if prescribed by your pediatrician. Keep the baby well-hydrated (continue breastfeeding or formula). Use lukewarm sponge baths if the fever is high.
If the fever lasts more than 3 days, gets very high, or if the baby is extremely fussy, sleepy, or feeding poorly, consult your pediatrician right away.
