My 7 week baby has his 6 week imminization vaccine yesterday at 11 am. After returning home as per the advice we have given paracetamol. However at night 1 am. he had 100.4 fever. Then we have another dose of paracetamol. Today at 1 p.m. he has again 100.2 fever and again we have given paracetamol. Now at 9 pm his temperature is again rising. It is 99.2 now. We have not given paracetamol now as the temp is not above 100. We are worried that the interval of fever has reduced. Is it normal after this immunization? He is 5.2 kg weight and doing pee 12 to 15 times a day as he do everyday. It seems he has not pain in his limbs.
