I've never posted before but my ds is due for his MMR soon and I'm scared to death about giving to to him. Can anyone reassure me? I'm not anti-vaccination but I've been doing some reading about MMR reactions and bad reactions can and do happen - these parents can't all be hysterical/wrong as the medical establishment seem to want us to believe. My ds had a bad reaction to previous injections and I'm really beginning to panic. What is a normal reaction to MMR? Thanks for any help.
