Reply #7: The reason the US switched vaccines is because of pressure

[mzmolly]

from so called anti-vaccination groups. However the study I noted appears to be in relation to the whole cell vaccine? Also, I wouldn't say my child had a "mild" case of pertussis, but she did have a more mild case than her fully vaccinated friend. Some studies may explain why? http://cvi.asm.org/cgi/content/abstract/CVI.00469-09v1

As to my breastfeeding my child, I was not at that time.

FYI, I simply posted the results of a study which indicate that those who are properly vaccinated, are spreading disease. If you want to call that "effective" be my guest. However, likening a non-contagious disease like tetanus to pertussis is missing the mark.
