A baby doesn’t need paracetamol unless they develop a high fever that tepid sponging can’t control and from experience, such vaccines that can lead to a fever are not given at 9 months so you really do not need it.

Kindly note that administering paracetamol after an immunization shot has to do with reducing fever associated with some vaccines side effects especially the PENTA or DPT but we don't have to take paracetamol for every immunization but then many don't know which is why especially at our health centres their practice of giving paracetamol at all immunizations, not necessary. Observe baby, if she develops fever above 37.5, give paracetamol.
