DS had his MMR today. DH had to take him as I couldn't get time off work. I tasked him to find out from the GP what the likely reaction would be (fever etc) but he forgot. Can anyone tell me when he will react if he is going to? Mum said he would react ten days later but that seems like a long time away. Is that right? No horror stories re MMR please just want to know about normal reactions (haven't googled for the same reason!)
