Science studies show the whooping cough vaccine does not protect against whooping cough infection, and is contributing to the spread of this disease.
About whooping cough
Whooping cough is caused by the bacteria Bordetella pertussis and Bordetella parapertussis.
The vaccine is called aP, meaning acellular pertussis, and is made from 3 components taken from pertussis bacterial cells. The 3 components are: pertussis toxin (Ptx), pertactin (Prn), and filamentous hemagglutinin (Fha). Some aP vaccines contain more components, such as Fim2 and Fim3.
Overview of the vaccine science
Scientists around the world have been contributing to an understanding of why whooping cough incidence has been increasing in areas with high vaccination rates. Findings include:
- The vaccine is contributing to the spread of infection, by suppressing serious symptoms but not infection and transmission in adults and children. See 1) Spreading infection
- The vaccine does not work against pertussis strains in circulation, and the vaccine is breeding the new resistant strains. See 2) New strains
- The vaccine does not work against parapertussis, and makes parapertussis more dangerous in the vaccinated than it is in the unvaccinated. See 3) Parapertussis
- Vaccine effectiveness and duration of protection has reduced. See 4) Efficacy and duration.
- The vaccine suppresses the immune response to adenylate cyclase toxin (ACT), a dangerous toxin pertussis bacteria produce in the lungs, due to the phenomenon of original antigenic sin. See 5) Vaccine suppresses immune responses.
- Cocooning, the practice of vaccinating a new baby’s close contacts, has been shown to be ineffective in preventing pertussis infection. See 6) Cocooning.
1) Spreading infection
- “In this study, we show nonhuman primates vaccinated with aP were protected from severe symptoms but not infection and readily transmitted Bordetella pertussis to contacts.”
Another study, from Santa Fe Institute
Whooping cough resurgence due to vaccinated people not knowing they’re infectious?
- “The dramatic resurgence of whooping cough is due, in large part, to vaccinated people who are infectious but who do not display the symptoms, suggests a new study.”
- “Althouse and Scarpino used whopping cough case counts from the CDC, genomic data on the pertussis bacteria, and a detailed epidemiological model of whooping cough transmission to conclude that acellular vaccines may well have contributed to — even exacerbated — the recent pertussis outbreak by allowing infected individuals without symptoms to unknowingly spread pertussis multiple times in their lifetimes.”
- “Their results also suggest that a practice called COCOONING, where mothers, fathers, and siblings are vaccinated to protect newborns, isn’t effective. ‘It just doesn’t work, because even if you get the acellular vaccine you can still become infected and can still transmit. So that baby is not protected,’ Althouse says.”

2) New strains
From the CDC:
Resurgence of Pertussis. (on page 6)
- “However, a recent study suggests another explanation for decreased vaccine effectiveness: an increase in Bordetella pertussis isolates that lack pertactin (PRN) – a key antigen component of the acellular pertussis vaccine.”

Evolution of whooping cough bacterium could reduce vaccine effectiveness
- “The bacterium that causes whooping cough, Bordetella pertussis, has changed – most likely in response to the vaccine used to prevent the disease – with a possible reduced effectiveness of the vaccine as a result, a new study shows.”
- “About 80 per cent of the 2012 whooping cough cases in Australia studied by the team were caused by pertactin-free strains.”

- These data capture genotypic shifts, including increased pertactin deficiency, occurring amid the current pertussis disease resurgence and provide a foundation for needed research to direct future public health control strategies.
- “In conclusion, the prolonged epidemic in Australia that began in 2008 was predominantly caused by SPs from cluster I carrying prn2 and ptxP3, which have been circulating in this country since at least 2000. There may be other unknown factors contributing to the increase of cluster I strains, but they appear to have a selective advantage over strains carrying non-prn2 and non-ptxP3 alleles under the pressure of ACV [acellular vaccine] vaccination.”
- “The use of acellular vaccines (ACV) has been associated with the recent resurgence of pertussis in developed countries including Australia despite high vaccination coverage where B. pertussis strains that do not express pertactin (Prn), a key antigenic component of the ACV, have emerged and become prevalent…Our findings of greater ability of Prn negative strains to colonise ACV-immunised mice are consistent with reports of selective advantage for these strains in ACV-immunised humans.”
- “Typing of genes encoding ACV [acellular vaccine] antigens showed that use of ACV may have driven antigenic changes of 2 MTs now predominant in Australia.”
- “Thus, we conclude that aP vaccination interferes with the optimal clearance of B. parapertussis and enhances the performance of this pathogen. Our data raise the possibility that widespread aP vaccination can create hosts more susceptible to B. parapertussis infection.”

- “Routine Tdap vaccination did not prevent pertussis outbreaks in adolescents. Among adolescents previously vaccinated only with DTaP, Tdap provided moderate protection during the first year and then waned rapidly so that little protection remained 2-3 years after vaccination.”
5) Vaccine suppresses immune responses
[Note – ‘linked epitope suppression’ is the same thing as ‘original antigenic sin’]
From Department of Pediatrics, David Geffen School of Medicine at UCLA, 2019
The 112-Year Odyssey of Pertussis and Pertussis Vaccines-Mistakes Made and Implications for the Future.
- “Because of linked-epitope suppression, all children who were primed by DTaP vaccines will be more susceptible to pertussis throughout their lifetimes, and there is no easy way to decrease this increased lifetime susceptibility.”
The following 2010 paper from the same group compares vaccinated and unvaccinated children, all with whooping cough, for their antibody response to various pertussis components. An earlier study by the group (2004) examined response to ACT, a dangerous toxin produced in the lungs by pertussis bacteria, which scientists have not at this stage found a way of incorporating into the aP vaccine.
Antibody Response Patterns to Bordetella pertussis Antigens in Vaccinated (Primed) and Unvaccinated (Unprimed) Young Children with Pertussis
- “In a previous study, it was observed that children who were diphtheria-tetanus-acellular pertussis (DTaP) vaccine failures had a minimal antibody response to the nonvaccine antigen adenylate cyclase toxin (ACT), whereas unvaccinated children had a vigorous response to this antigen. Specifically, the convalescent-phase enzyme-linked immunosorbent assay (ELISA) antibody geometric mean value (GMV) in response to ACT in 20 unvaccinated children with pertussis was 872 ELISA units (EU)/ml, whereas the convalescent-phase GMV in 10 DTaP vaccine failures was only 49 EU/ml.” [This is a huge difference]
- “A second hypothesis, which we favor, is that the findings can be explained by LINKED EPITOPE SUPPRESSION caused by preferential responses of memory B cells following secondary exposure to vaccine components.”
- “The original exposure essentially “locks in” the immune response to certain epitopes and inhibits the response to linked epitopes even following subsequent exposures.”
Here is the earlier paper by the group (2004).
Determination of Serum Antibody to Bordetella pertussis Adenylate Cyclase Toxin in Vaccinated and Unvaccinated Children and in Children and Adults with Pertussis
- “Of particular interest is the lack of a significant ACT antibody response in children for whom the DTP or DTaP vaccines failed. This induced tolerance is intriguing and may be due to the phenomenon called “original antigenic sin” . In this phenomenon, a child responds at initial exposure to all presented epitopes of the infecting agent or vaccine. With repeated exposure when older, the child responds preferentially to those epitopes shared with the original infecting agent or vaccine and can be expected to have responses to new epitopes of the infecting agent that are less marked than normal. Because both vaccines contained multiple antigens (i.e., PT, FHA, PRN, and fimbriae), the patients who had been vaccinated responded to the antigens that they had been primed with and did not respond to the new antigen (i.e., ACT) associated with infection.”
6) Cocooning (vaccinating a new baby’s close contacts)
- In our setting, vaccinating parents with dTpa during the four weeks following delivery did not reduce pertussis diagnoses in infants.
Australian research shows the source of Pertussis infection is most commonly fully vaccinated siblings.
Finding the ‘who’ in whooping cough: vaccinated siblings are important pertussis sources in infants 6 months of age and under
- “Fully vaccinated siblings aged 2 and 3 years were the most important infant pertussis sources in the peak epidemic period of this study, suggesting that immunity may wane in this age group before the vaccine booster at 4 years. Even if it were possible to fully cocoon infants through a combination of parental vaccination and ensuring siblings were fully vaccinated, the possibility of transmission via breakthrough disease in siblings would persist.”
Here in Australia, unvaccinated children are blamed for young infants becoming seriously ill or dying from pertussis. However, when we had much lower vaccination rates for pertussis, the number of reported cases was also much lower.
In 1991, around 71% of Australian children were fully vaccinated and there were only 347 cases of Whooping Cough, while in 2011 with over 90% of children vaccinated, we had 38,758 cases. How can the unvaccinated be blamed for this disease spreading?

Cocooning (i.e. ensuring all people in contact with a baby have had a booster aP shot):
In this 2014 video Professor Ann Koehler, Director of the Communicable Disease Control Branch in South Australia, explains that the pertussis vaccine does not work, so it could not protect a newborn baby in a cocooning program.
So we know pertussis vaccination doesn’t prevent infections so we could not see how it could be all that good for a cocooning program that was meant to prevent infection all around a baby.
Dr Ann Koehler – Whooping Cough Cocooning Strategy Scam
Full version of the talk is here: SA Vaccinology Update: Associate Professor Ann Koehler
- “Parents across Australia will no longer receive free whooping cough vaccinations because it is not effective in protecting newborns from the potentially deadly illness, a parliamentary committee has heard.”
- “”The PBAC, which is totally independent and very expert, has determined that there is no clinical effectiveness of this strategy,” Professor Brook said. He said this had made it clear the cocooning strategy should not be continued.”
[Note 1 – This abrupt and decisive change in policy might quite possibly indicate that the vaccine had been found to be not just ineffective in preventing infection or transmission but found to INCREASE THE RISK OF TRANSMISSION to newborn infants, but of course he could not say that.
Note 2 – This 2012 decision has now been superseded, has Victoria’s Labor health minister Jill Hennessy looked at the science?]
Another Australian immunisation official Professor Peter McIntyre spoke in a podcast in May 2017 about how the pertussis vaccine does not stop pertussis from circulating:
even with 100% of kids getting immunised about pertussis, pertussis, unfortunately still circulates in the community

Food for thought
This article questions a paper that recommends P vaccination of pregnant women:
Vaccinating pregnant women “halves the risk of pertussis in infants’ first four months” ~ A critique by Dr Suzanne Humphries
- “But this plan, sometimes referred to as “COCOONING” has failed and will never work, no matter how many boosters are given to household contacts. That is because booster “immunity” is short-lived, and because of the issue of original antigenic sin [also called linked epitope suppression] which makes the vaccinated more susceptible to infection and longer asymptomatic carriage than the naturally immune.”
- “Since a vaccine creates different immunologic response pathways than natural immunity, the body will act according to how it was programmed by the vaccine.”
- “In natural immunity the body reacts very strongly to ACT, but because of original antigenic sin, and the absence of ACT in the vaccine, the vaccinated are not programmed to respond at all to it. ” [ACT is a dangerous toxin produced in the lungs by pertussis bacteria.]
- “When a vaccinated person contacts pertussis again, the bacteria can get a good hold, because there is little to stop it from doing so. The immune system will not respond to ACT in the future, because the program has been set by the first contact which was the needle, not the bacteria.”
- “It is true that maternal protection is important, both via transplacental and breast milk immunity. This type of immunity protects infants for up to two years, and certainly for the most vulnerable first six months of life, but not in the post vaccine era because the short lived pseudo immunity of vaccines destroyed the true herd immunity that once protected newborn infants.”
