My baby is 9 month old. Day before yesterday gave MMR vaccine. And yesterday he got feverish like 100.3 f. Again at night he got fever 101.5. today visited ped . He suspects a viral infection as no other symptoms are present. He told to give paracetamol but fever comes and goes . Main thing is fever only in torso and head very hot. Legs and hands appear normal or sometime cold . Can u plz help me what this could be. I am very worried as this has happened for the first time. Plz mother's share your experiences if gone through same thing
