I am no fan of vaccines.  Neither do I wish to get involved in a
flame war over the issue.  My youngest child has never been immunized.
Immun. HAVE caused flare-ups in their allergies.  Erin, the youngest,
nevertheless was BORN allergic, as was Curran, who was immunized late.  So
while immun. may make allergies worse, I would not say they are THE ultimate
or only cause of allergies and autism.
