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.
However, vaccine-induced immunity wanes after 5 to 10 years, making the vaccinated host vulnerable to infection (3). This susceptibility has been described in outbreaks of pertussis infection in highly vaccinated populations (3-6). A recent study by Yaari et al. showed that infection in a vaccinated person causes milder, nonspecific disease, without the three classical clinical stages (7). Whooping cough is seen in only 6% of such cases; instead, the illness is characterized by a nonspecific, prolonged cough, lasting several weeks to months. Because of these atypical symptoms, pertussis infection is underdiagnosed in adults and adolescents, who may be reservoirs for infection of unvaccinated infants (8-10).
What is certain, however, is that vaccine-induced immunity against infection does not persist throughout adulthood. In France, booster vaccinations have been recommended for adolescents and teenagers (18).
ATLANTA — The whooping cough vaccine given to babies and toddlers loses much of its effectiveness after just three years – a lot faster than doctors believed – and that could help explain a recent series of outbreaks in the U.S. among children who were fully vaccinated, a study suggests.

this is just ridiculous! they come out with a vaccine and say its to protect you from getting a sickness, but the vaccine is the thing that gives you the ACTUAL sickness they promised to protect you from!!
absolutely sickening!!!!!!!!!!
*hugs to you OP* i have experienced similar coughing puking.
Um... yeah, that's how vaccines work.

often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins. The agent stimulates the body's immune system to recognize the agent as foreign, destroy it, and "remember" it, so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters.

I have a feeling you didnt read one of the studies you linked:

The study is implying that there should be more vaccines given and booster shots given more often, because people that have had their vaccines wear off, develop the infection asymptomatic...
Meaning, the get whooping cough, without the "whooping",
which really isn't a bad thing, but the are highlighting the fact that it gets overlooked, and therefore not treated properly....edit on 26-4-2012 by boncho because: (no reason given)
This is reflected in this following article, which is basically suggesting that people get booster or be revaccinated every 3 years or so:

Health officials say that at the rate things are going now, we could see as many as 3,000 cases this year, which would be the most in the state in six decades.
Teens and adults are urged to get vaccinations. Officials note that vaccination is especially important for those in close contact with babies less than 1 year old.
I just don't think vaccines are a negative in this case, as some of the blogs and "naturalnews" types are making it to be.
Health officials are looking into whether cases like the dozen found in Philadelphia might be one reason the nation just had its worst year for whooping cough in six decades. The new bug was previously reported in Japan, France and Finland.
