take all of the bad ingredients out of vaccines and you have no vaccine.  
mercury, aluminum, anti-freeze, pus, endless list of danger.  visit vaclib.org. 
 phone numbers of pharma companies who are obliged, by law,if you care to check 
with them on the ingredients in their vaccines. there are forms on this site 
that will excuse your child from vaccines at school.  besides, there is nothing 
in my constitution that says my government (public schools) can put a foreign 
substance into my body.    personally, i got my multiple sclerosis within a 
week of a vaccine.  my step-grandson (3 months old) died few days after 
vaccine.  think of your pets as well.  vaccines upset their auto-immune systems 
as well.  muttmom vicki hood
