There are several vaccines that do not prevent transmission ~ Tdap and pertussis are really good examples. There is absolutely no evidence that these vaccines prevent transmission ~ and even further there is some evidence that a vaccinated individual can be a carrier. The vaccine can lessen the symptoms of pertussis thereby making it easier to spread to those "too young to vax".
Â
Another is that vaxing their kids against chicken pox actually shifts danger to the older population by causing more frequent bouts of shingles. I was talking with my neighbor the other day who was asked to get a shingles vaccine. This never used to be as big of a problem ~ but the wild virus is not out there boosting our natural immunity!
Â
There is also no evidence that the HPV vaccine being administered to young girls (and a similar vaccine now approved for young boys) prevents transmission either!
Â
IMHO ~ unless they are holding test subjects in a stainless steel drum ~ there is no evidence on any vaccine that transmission is prevented by vaccinating. It is only an assumed theory on the part of scientists...
Â
There is a lot of danger in vaxing...

But I agree with the PP ~ I have given up trying to make up someone else's mind about vaccinations. I am tired of having crappy propaganda shoved down my throat so I only mention our vax status when I absolutely have to do it or when I am asked by a parent who is considering/researching not vaxing. My minister is on a big HPV kick right now ~ we attend a very liberal church however he seems to feel that the HPV vaccine is a modern scientific miracle and is going to save tons of lives! I have tried to kindly say ~ even if it was a really good vaccine and did what it proclaims to do (which I am skeptical about) ~ it is not going to get to the girls who actually would benefit from it because it is a 3-shot series at $400 each. Those who are actually dying of cervical cancer are lacking in healthcare coverage and funding to begin with...why not offer them annual pap smears and exams instead (probably save a good portion of that money spent vaccinating). But alas he continues to believe that this vaccine is going to save women every where ~ and I have decided that it is just not worth my time to debate someone or something that doesn't want to be debated (and likely has a lot of fear in thinking that he has just vaxed his 3 teenagers ~ 1 girl, 2 boys ~ for something that could potentially be dangerous).Â
