Fever after immunizations?

Question

I gave the first shots of immunization to my 6 month old baby (DTaP, Hib, Polio) last Friday and a few hours later he was fussy and got a fever of about 101. Kept giving him Tylenol for 2 days until Sunday evening but he is still feverish. He is not that fussy now and is taking his bottles and some food but after about 5 hours from giving him tylenol his fever is going up to 101 again and 103 in the evening. Is this normal? Anyone else experienced this? Will take him to paedetrician tomorrow.

I thank you all for your kind replies. In fact we called his doctor and he said to keep giving him tylenol every 4 hours till tomorrow and he will see him tomorrow. I am so preoccupied.

Answer 1

My daughter used to run fevers for 2-3 days after her shots. It is normal, but I think I would still see the pedatrician since the fever was 103. Oh, and when he gets the 18 month old shot, he may even have a knot, and be red and swollen around the shot site, in addition to the fever. Lots of luck.

Answer 2

Yes it's normal to run a low temp after immunizations. The tylenol is a good measure and you can probably continue giving it to him until he sees the doctor. But he may be coming down with something as well at the same time.

A 103 temp is rather high. You may want to call the pediatrician now and ask rather than wait. If the temp is not controlled through tylenol but going up, it can indicate another problem or a severe reaction to the shots. You may want to call to reassure yourself or to investigate there is another problem going on. A low temp is usually thought of being one of under 100.

Check it out please. I had a child at the age of 2 weeks who woke up with a minor fever. Gave her tylenol but the fever kept escalating to over 103. Found out it was viral menigitis and had to have her hospitalized. Was I ever glad we did that!! Viral menigitis is not fatal but high fevers are not good for babies, and need to be controlled and brought down. She's now 21 and very healthy :)

Answer 3

Fever right after the immunization I experienced (and was told it was common). But 103 2 days later seems high to me and I would definitely follow up with his doctor. In fact, I might even call the on-call doctor to ask whether I should do anything else sooner.

Answer 4

It is an adverse reaction to the shots. Unfortunately, it is normal reactions that Dr. usually don't report to VAERS (Vaccine Adverse Event Reporting System) which over sees how many reactions that kids are getting from the shots. I would become very educated in what are in the shots and the reactions that can be caused from the shots, so in the case of a severe reaction you will know how to respond to make sure that your child gets the best care and what to look for with reactions that may take weeks to appear.

Answer 5

fever after immunization is completely normal but it should not last to long and 103 seems a bit high.

Answer 6

Yes anything over 101 you should take him to the doc. Good thing you called you did the right thing.

Answer 7

Perfectly normal. If his fever isn't above 104 an he seems fine, I wouldn't worry to much about it.
My son participated in a vaccination study and the doctor said it was quite normal to have a low grade fever for up to a week after.

Answer 8

Motrin gets the fever down faster, (baby motrin)
Sounds normal, but get that fever down, use vinegar cool compresses.(not cold)

Answer 9

Yep, normal, but I don't remember it lasting that long with mine. Innoculations are a weaked (attenuated) version of the real thing. That is what stimulates the antibodies.
