Re: Vaccines and fever
My son is almost 7 months now, but he had a low-grade fever after his 2 month shots, and it lasted about two days. I'm not sure what the average is, but I would be more concerned with how high the temperature gets, as opposed to duration. If the fever was high, like 104 F for two days, I would definitely call the doctor. Otherwise, I'd just try to keep the temp down and keep him comfy. Hope your boy is feeling better soon.
