OP- You need to do what you feel is best, please don't let any one preasure you into doing it if you feel its the wrong thing.
I was wary about giving dd2 the MMR, i put it off and the gp kept phoning me and telling me 'there was no risk', i eventually got it done, dd2 had a reaction, we then had the same with the booster, i wanted her tested to see if she needed it, gp refused and again i had phone calls preasuring me into getting the booster, i was worried as dd2 was referred to pead with Autistic traits 2 months after the first MMR (i was worried she would react to the booster), again i felt forced into having it done. The day after the booster dd2 had a bad reaction and we ended up in hospital (she was ok though). Dd2 is now 6 and diagnosed with ASD.
I also have another dd who was clearly autistic before the MMR so make of it what you will.
You may have read my post on the other thread, i am unsure if the MMR caused my dd2's ASD, her sister already had a dx of aspergers so asd in in the family. I'm still being told there is no link with the MMR and Autism.
I think every parent should have the choice of the MMR or single vaccines.
Most children will have no reaction at all to the MMR but i think theres always a risk with having 3 vaccines in one (but thats just my view).
Do what you think is best, the single vaccines cost around £300, i think its important for children to be vaccinated and wouldn't advice anyone not to get there dc's vaccinated.
