What Happens to Some Children After Vaccination

My son developed a fever immediately after the vaccination. Of course he had other vaccinations as well (the standard). He ran a fever for 2/3 days. However, his behavior has changed. He won't play by himself at all. If I try to play with him he want me to hold him. He buries his face in my legs or the sofa. He'll grab my hands and hold them sometimes rubbing his face in them.He has seemed weaker and very fussy (clingy too!!). He won't let me leave his sight. Also, he had some small bruises on his thighs (maybe from the injections)? Now, it's exactly one week later and he's running a super high fever 102 with tylenol. I plan on sleeping on his floor and monitoring him every hour through the night.Is this a normal reaction to the MMR/12 month checkup. He is allergic to eggs and I've found the MMR is made from egg protiens.
