I posted a thread on this topic nearly a year ago when my son was only a few months old. Now that he's 13months old, the time for the MMR has come round and my wife and I are pretty nervous for the wee fella. Naturally we want what's best for him and are going ahead with the jab. But is this what's best for him? I guess I'm really just looking for some reassurance from the general punters out there. Your views and comments once again on this long debated topic would be appreciated.
