ds1 booked for his MMR booster on Thurs. I recall that after his first MMR he was unwell on and off for a few weeks afterwards, with temperature/mild versions of the MMR components. given that, is it likely to be the same again? does anyone know the timescale? <futile worrying about temperature coinciding with holiday>
not all kids do. But a rash could indicate immunity to measles or rubella and there is a good chance (5% for measles, 15% or so for mumps) that the kid is not immune, despite a reaction to one of the other components. I guess the second shot is easier/cheaper than to test every kid for immunity after the first shot. But some parents do, and I think that is a viable alternative (and they could delay the second MMR until uni/college)
My dd2 had a small reaction to the first, i didn't want her to have the 2nd (due to her reacting to all her injections and being diagnosed with ASD), in the end we went through with it and the next day was spent on the childrens ward after a bad reaction (she was fine the day after). I think its quite rare to get a severe reaction (i dont know many who have had any reaction) so don't let my story scare you .
A blood test is more traumatic than an injection - especially if the person taking the blood is inexperienced or has difficulty finding a vein. I would rather my dd have the second jab than have blood taken. It is also cheaper and quicker to give 2 doses than call all children to have their immunity checked.
