Fever after Immunization

Hi mommies! I need some comments. Yesterday was my baby’s Immunization, Penta (5in1) Vaccine and PCV Vaccine, plus my OPV drops pa. Then at night, nagkaron xa fever 38.4, it dropped to 38.1, this morning it became 39.2. Im giving him paracetamol every 4 hrs though, .7 ml. He just turned 4 mos on Sep. 6. Is this normal reaction?
