2 month son fever of 101.1 my son is 9.5 weeks old and got his first round of shots today. he weighs 12.2 pounds. i've tried calling his doctor and have been on hold for 45 minutes. what do i do?

I : I am sure you have had contact with the doctor by now. I am answering this question for anyone else reading this post, and also for you for the future. Fever after vaccines is very common. Call the pediatrician immediately if your child has a fever over 105 degrees fahrenheit. If he/she becomes pale, limp, cries constantly for three or more hours, or starts shaking, twitching or jerking call 911 or present to the emergency room. Another important thing to do after vaccinations is to monitor for signs of an allergic reaction. This includes difficulty breathing, hoarseness, swelling of throat, weakness, rapid heart rate, dizziness, paleness or rash. If so call 911. Take care.
