DS is 3.4yo. Yesterday at 12 he had his first MMR and a diphtheria, tetanus, pertussis, polio booster.
At bedtime, around 190\ his temp shot up to 39. He was shivery and quite miserable. Gave him Calpol but it didn't touch the temperature so gave him ibuprofen at 2130.
He's just, at 0030 puked quite a lot.
Is this a known, if unusual, reaction? You'll notice that we delayed his MMR a bit, so it's clear that I have had doubts in the past (not about autism) so I may just be over reacting. I generally don't deal well with my DC being ill so it is difficult for me to judge.
Should we just keep an eye on him and report reaction via yellow card system?
