Hello! Today we gave the child their first AKDS vaccination. It's the first one, and it's been two months since then. There's no fever yet, but they're crying a lot, being fussy, and the doctor said that the temperature might rise closer to night. He also said we can give them an antipyretic medication. What kind of medicine can we give for a fever? What was the reaction like for others? How should we proceed? We're so upset ? help ?
