A study just published in BMC Medicine by Santa Fe Institute Omidyar Fellows Ben Althouse and Sam Scarpino used algorithms to see what caused a resurgence of whooping cough (pertussis) in the U.S. and UK.
It has now been openly declared that the DTaP vaccine is causing the uptick in whooping cough.
Out of the hypotheses, asymptomatic shedding was the final detectable problem. However, the authors have more to say on it, some of which sounds very contradictory coming from researchers who have proven that the mechanism of the acellular DTaP is, in part responsible for the spread of a dangerous bacterium.
Highlights, and this writer’s observations:
- Researchers hypothesize 4 causes of whooping cough (pertussis) resurgence, zeroing in on low vaccine coverage and unvaccinated populations, failure of vaccine, microbial resistance, and asymptomatic shedding from newer, acellular vaccines.
- Vaccinating individuals in close contact with infants too young to receive the vaccine (“cocooning” unvaccinated children) may be ineffective and prove negative.
- It isn’t really explained how asymptomatic transmission accounts for infecting the vaccinated population and why even more vaccine coverage would help…
- Authors claim that before a new vaccine is ready for clinical use, other options are necessary for reducing incidence, including vaccination of pregnant women.
- According to Science Daily’s assessment which focuses on “anti-vaccine” sentiment, the authors vigorously want higher DTaP rates regardless, and present the information for policy and vaccine makers. Other outlets have implicated that a demand for safer vaccines in the 1990s caused the problem, but they dismiss death and injury associated with previous whole-cell vaccines. The burden of safety is to be on the manufacturers.
