In March 2012, dangerous new strains of whooping cough bacteria were reported in Australia. Researchers studying the strains said the vaccine itself was responsible. The reason for this is because, while whooping cough is primarily attributed to Bordetella pertussis infection, it is also caused by another closely related pathogen called B. parapertussis, which the vaccine does NOT protect against. Two years earlier, scientists at Penn State had already reported that the pertussis vaccine significantly enhanced the colonization of B. parapertussis, thereby promoting vaccine-resistant whooping cough outbreaks.
According to the authors:
“… [V]accination led to a 40-fold enhancement of B. parapertussis colonization in the lungs of mice. Though the mechanism behind this increased colonization was not specifically elucidated, it is speculated to involve specific immune responses skewed or dampened by the acellular vaccine, including cytokine and antibody production during infection. Despite this vaccine being hugely effective against B. pertussis, which was once the primary childhood killer, these data suggest that the vaccine may be contributing to the observed rise in whooping cough incidence over the last decade by promoting B. parapertussis infection.”
Also does this guy understand that saying that oh my god B. parapertussis also causes whooping cough, actually means yes the whooping cough vaccine works, because it is pprotecting against B. pertussis infections?
And that this statement "In the study cited above, the researchers noted the vaccine’s effectiveness was only 41 percent among 2- to 7-year-olds and a dismal 24 percent among those aged 8-12" whilst true is not actually stating what the authors thought. The authors of that study actually were arguing for more vaccines since it was apparent that the scheduling wasn't enough to ensure immunity.
Need I go on?
