C.H.
I would contact your doctor first, but is does sound common. My pediatrician gives me a brochure with every vaccine. All the side effects are different. Some spike a fever 1-5 days and some are as much as 7-10 days (specially the chicken pox vaccine). she may be reacting to more than one of the shots. If the Tylenol is not working try Motrin, I have found Motrin more effective that Tylenol and it lasts 6-8 hours instead of 4-6. good Luck!!
