Lead author and microbiologist Dr Laurence Luu, who led the team of researchers with Professor Ruiting Lan, said whooping cough’s ability to adapt to vaccines and survival in humans might be the answer to its surprise resurgence despite Australia’s high vaccination rates. The research now shows that evolving strains of pertussis make further adaptations to survive in their host. (This pertussis vaccine is one of the doses included in the three dose DTaP vaccine.
“We found the whooping cough strains were evolving to improve their survival, regardless of whether a person was vaccinated or not, by producing more nutrient-binding and transport proteins, and fewer immunogenic proteins which are not targeted by the vaccine,” Dr Luu said.
“This allows whooping cough bacteria to more efficiently scavenge nutrients from the host during infection, as well as to evade the body’s natural immune system because the bacteria are making fewer proteins that our body recognizes.
“Put simply, the bacteria that cause whooping cough are becoming better at hiding and better at feeding – they're morphing into a superbug.”
This problem is not unique to Australia. Most whooping cough in the world today is the result of mutations spurred into existence via vaccination.
US whooping cough outbreaks occurring in fully vaccinated children
15 children at a Falmouth High School in the Cape Cod area of Massachusetts came down with the respiratory illness; all were vaccinated. No unvaccinated children contracted the infection. It appears the vaccine makes children more susceptible to infection, causing the pathogen to mutate and take advantage of the overly-vaccinated, overly-burdened immune system.
Another outbreak occurred on Dec. 4t 2019 at the St. Theresa Catholic School in Memorial Park. The outbreak occurred at a school that has a 100 percent vaccination rate, yet the students rapidly became infected with whooping cough that they were vaccinated for. The outbreak was so bad, the school had to be shut down.
The science is becoming clear on whooping cough vaccination: Even after children are subjected to the three dose regime of this vaccine, they become 15 times more likely to contract the illness five years after they completed the vaccine series. If children do gain any immunity to these strains, it is short-lived, but more importantly, the vaccines are causing whooping cough strains to become super bugs that put everyone at greater risk of infection.
Australia’s whooping cough epidemic from 2008 to 2012 saw more than 140,000 cases – with a peak of almost 40,000 in 2011 – and revealed the rise of evolving strains able to evade vaccine-generated immunity.
