Ds2 (15 mths) had his first MMR injection on Monday afternoon. Since 7pm tonight he's been running a temperature. I've just been in to see him and given him some nurofen as his temperature is up at 39.5C.
Can this be a reaction to the MMR? I was under the impression that it was supposed to be about a week before anything happened? (Although I have vague memories of ds1 reacting "fast" too - around 4 days before a temperature). I didn't get a sheet this time round listing the common reactions - does this sound like it's MMR related? Is it likely to go away again within the next 24hrs?
