having fever after jab is common. mine one oso hav it on the first jab. after tat, we learnt. we boil 'pao sen' for him before the jab, and immediately taken the jab, let him take paraccetomol even no fever. it helps to supress the fever. on his 2nd n 3rd jab, no more fever
fever till 38.5 degC in 24 hrs is still ok, give paracetomol, put cold towel, drink more water..., otherwise must alarm the PD for further treatment
