OK, as of yet I haven't posted much about vaccines. I still feel as though I need to do more research using the CDC's own website and then go from there. Here is one example I have found.
The conclusion of this study is that people who ARE vaccinated for Pertussis can be silent carriers of Pertussis; transmitting it to the vaccinated and unvaccinated alike. This terrifies me. The wording is a bit overwhelming in this study but you can cut to the chase by scrolling down to the "conclusion" part of it. Here are some quotes from the study (again, from the CDC's own study)
"We also observed that DPT vaccine does not fully protect children against the level of clinical disease defined by WHO"
"Vaccinated adolescents and adults may serve as reservoirs for silent infection and become potential transmitters to unprotected infants"
