I'm not 100% sure but i have a friend who has had her needles done through a doctor and they will do them seperately for her, she has to pay for them i think but she didn't mind as it was her choice not to do them all at once.
FWIW my DD had her 12mth needles yesterday all 3 and it's heartbreaking but i think for me personally i prefer to do them in 1 day and get it over with rather than have her jabbed on 3 seperate occasions.
Thanks ZF. The MMR one can't be separated as the manufacturer no longer produces the individual vaccines for measles and mumps. Actually, I'm now thinking it's better to give the one jab as well. The total amount of other stuff (preservatives, residuals from manufacture etc) in the vaccine is probably less with one than with three. Plus, I should trust that I'm keeping her immune system strong naturally so her body can cope with it.

Persephone - Thanks. I will look into getting that book.

Alicia - That's so scary for your friend. I hope their DD is okay and that the family can heal.

Hmm, not sure how I feel about this. The consumer information for priorix (MMR vaccine) advises caution (not contraindication as per my OP) for those with reaction to egg. Yet the national immunisation register says that there it can "safely be given". Still, I'll stick with my decision as it's what I feel comfortable with.
