There are a few potential problems here. One is an egg allergy. If the
child is not allergic to eggs, this won't be a problem. If he is egg
allergic, he can still be tested for allergy to the specific vaccine - the
eggs used in some vaccines are processed enough that many egg-allergic
children do not react to the vaccine.

Many vaccines also contain preservatives. If your child experienced a
serious reaction or the rash was thought to be severe, you might consider
asking for a preservative-free vaccine, or you might want to test the child
for allergy to the preservative prior to revaccination.

There was a recent stir about vaccinations and various disorders, including
immune disorders and autism. To my mind, there is no more that
circumstantial linkage. As always, you must, as a responsible parent, weigh
the risks of vaccinating against the risks of not. And you must filter out
the persuasive but unproven arguments from the refereed research.

Good luck,

Mark
