Pertussis vaccine does NOT prevent transmission?  

post #1 of 45

Thread Starter 
Okay, I asked this in another thread, but then I figured I'd just start a new one. Can anyone show me the links/evidence/research to support the statement "The Pertussis vaccine does NOT prevent transmission" ?
People always seem to be saying that, but I can't find the literature on it. And does anyone know where can I look to find out what other vaccines do not prevent transmission?

Also, if that is true, that means that they are just lying to everyone with the "I did it for Sophia" campaign?

Thanks!

I have never heard of the "I did it for Sophia" campaign.

(it's one of my big pet peeves...)

it's the print/tv campaign to push the adult TDaP.

from sanofi pasteur's website:

To protect your baby from pertussis, anyone who spends time with your baby should be protected from pertussis. Don't be shy about asking people if they've been immunized and make sure they understand how important it can be to the health of your baby.

Oh well that is why I have never heard of it then. It's for the new vax. And I have TIVO and don't watch commercials. I also don't read mainstream magazines. They tend to irritate me.

Yes. You are being misled, imo.

Here's a link to a study that discusses (among other things) the fact that they believe that children (even young, recently vaccinated children) can be silent transmitters of pertussis.

http://www.cdc.gov/ncidod/eid/vol6no5/pdf/srugo.pdf

Quote (page 3 of 4: Conclusion first paragraph)bolding mine

Quote:
The effects of whole-cell pertussis vaccine wane after 5 to 10 years, and infection in a vaccinated person causes nonspecific symptoms (3-7). Vaccinated adolescents and adults may serve as reservoirs for silent infection and become potential transmitters to unprotected infants (3-11). The whole-cell vaccine for pertussis is protective only against clinical disease, not against infection (15-17). Therefore, even young, recently vaccinated children may serve as reservoirs and potential transmitters of
infection.

What about the a-celluar vaccine for pertussis?

the acelluar pertussis vaccine is LESS effective... so I don't see how it could provide protection against transmission when the old one didn't...

Don't have time to search for links right now, but it's well known if you know what to look for and have the patience to search.

Yah, even in the old, old, old studies (back when the DTaP was tested in Japan...oh in the late 80's/early 90's??) all the stuff said the a-cellular wasn't as "good" as the whole-cell (but was supposed to be "less reactive" and was supposed to halt the "brain-damage" scandal)...can't remember the specifics right off the top of my head though

Its good to see that written out so clearly. I have always suspected that since diseases come from germs and that vaccines don't really kill germs they just give you immunity (sometimes) that the idea of vaccinating yourself for other people just doesnt' make a whole lot of common sense.

LOL. You're not slow. I mean it makes sense to me, but still I don't really understand how we have eradicated polio and smallpox if we haven't eradicated the germs, so obviously there is something there that I'm not quite getting.

It makes my head hurt.

Polio hasn't been eradicated. It still affects millions of people.

I stand corrected.

Why did I think it was eradicated? It seems like I have heard that a lot.

You don't hear about polio infection in the United States. At least not often. There were some secondary infections from the OPV a few years back and they did some testing in the Amish population.

Some vaccines do seem to prevent carriage. The three that definitely do not prevent carriage are Tetanus, Diptheria and Pertussis vaxes.

But which ones DO? And what evidence do you have to show that Tetanus, Diptheria and Pertussis don't? And I'm not trying to start a fight- I'm still researching all of this!!!

See post #6 for a link.

The reason they don't prevent transmission is because they don't kill the bacteria that cause the disease. They make the body able to resist the toxin that the bacteria release. This toxin is what actually makes the person sick. This is also the reason for the claim that being vaxed will make your case of pertussis milder, because even if you don't get the full effect, total blockage of the toxin, you might get partial blockage and cough less and so on.

As to which vaxes do prevent transmission. This is a big research job. Off the top of my head, I would say Hib and Prevnar. The same ones that have the serotype replacement problems.

Varicella (CP) vax seems to prevent transmission, but also sometimes spreads CP. It also wears off rather quickly in the absence of circulating disease, so it will require frequent boosters.

So, a start at least.

Measles, Mumps, Rubella and Chickepox (when it works) should prevent transmission.

As should Hib and prevnar.
