She was sincere and that's appreciated.
The featured study also suggests that the acellular pertussis vaccine loses much of its effectiveness after just three years. This is much faster than previously believed, and could also help explain the recent whooping cough outbreaks in the U.S.
Unfortunately, stacking on additional booster shots is likely to make matters worse rather than better, especially in light of the fact that the mass use of existing pertussis vaccines has already led to vaccine-resistant strains that are still evolving and could become much more virulent.
The new mutation, which some researchers are calling “P3,” is a strain that produces more pertussis toxin (PT).
Pertussis toxin is the part of B. pertussis bacteria that is most responsible for the neurological complications of both pertussis disease and DPT and DtaP pertussis vaccines, and is also most responsible for stimulating an immune response. The acellular pertussis vaccines, which were developed and tested in the late 1980′s and early 1990′s, do not include the mutated strain.
Another reason why whooping cough cannot be entirely eradicated is the fact that there’s another Bordetella organism – parapertussis – that can also cause whooping cough. The symptoms of B. parapertussis, while often milder, can look exactly like B. pertussis, but doctors rarely recognize or test for parapertussis. And, there is NO vaccine for it.
One difference between recovering from B. pertussis whooping cough and getting the vaccine is that recovery from whooping cough confers a naturally-acquired immunity that is stronger and longer lasting than the artificial immunity induced by the vaccine. Vaccination requires more and more booster doses to try to extend the artificial vaccine immunity.
