Hi my DS1 had MMR today (13 months) he pulled his arm away as they sometimes do and I had to have the rest put in on a second attempt but as the nurse said oops and pulled away i felt some of the liquid on my hand indicating that it din't all go in to his arm,is this OK as i don't feel he had the full dose??? The nurse just said, thats ok when I mentioned it so I am unsure......
