(NaturalNews) In the 1990s, a new acellular pertussis (whooping cough) vaccine (DTaP) was introduced in the United States and other countries. Prior to that, a whole-cell pertussis vaccine (DTP) was used. The whole-cell vaccine had moderate efficacy (with multiple booster doses) but caused relatively high rates of seizures, other neurological disorders, brain damage and death in susceptible children. Due to the high rates of serious adverse reactions, the acellular vaccine was introduced in its place.

The acellular vaccine was believed to be more safe, but authorities made this tradeoff in exchange for a vaccine that was less effective. Not only was the new pertussis vaccine just partially effective when it was introduced, but in the past several years studies have shown that the way in which it is manufactured -- to fight against some but not all strains of Bordetella pertussis toxins -- actually promotes natural selection, or pathogen adaptation. The vaccine has caused pertussis microorganisms that are associated with whooping cough in humans to mutate and become more virulent. The vaccine is not effective against these new strains that are now circulating throughout society.

Here are a few of the many important papers documenting pertussis vaccine failures:

Emerging Infectious Diseases recently published "Bordetella pertussis strains with increased toxin production associated with pertussis resurgence." A highly virulent strain of pertussis recently emerged from within pertussis-vaccinated populations. This new strain produces 1.62 times more lethal toxin than the old strain that the vaccine was designed to fight against. (1)

Pediatrics recently published "Why do pertussis vaccines fail?" Current pertussis vaccines fail due to genetic changes in the circulating strains of Bordetella pertussis and from inflated estimates of vaccine efficacy -- the vaccine's true efficacy may be as low as 40% -- not because too many people are unvaccinated. According to the author of this paper, "Vaccine use has resulted in genetic changes in [pertussis toxin], [pertactin], and [fimbriae] [virulence factors] in circulating B pertussis strains, and it has been suggested that this has led to increased vaccine failure rates." (2)

The journal Vaccine recently published "Imperfect vaccine-induced immunity and whooping cough transmission to infants." Children that are vaccinated with DTaP to protect against Bordetella pertussis are more likely to contract whooping cough from Bordetella parapertussis. Apparently, "vaccine-driven pathogen evolution" selected for this other species of pertussis that can infect more efficiently after vaccination. According to the authors of this paper, "There is evidence from both prospective epidemiological surveillance and recent experiments in model organisms that immunization with the acellular vaccine may actually increase the host's susceptibility to infection by B. parapertussis." (3)

A recent paper published by the Proceedings of the Royal Society B: Biological Sciences investigated the behavior of the Bordetella pertussis pathogen population under pressure from vaccination. Cases of pertussis in vaccinated children have increased dramatically since the introduction of the acellular pertussis vaccine. Vaccines that provide imperfect immunity (i.e., the acellular pertussis vaccine) can increase the level of pathogen circulation, making it more difficult to eliminate the disease. According to the authors of this paper, "The fact that populations of B. pertussis may have evolved to circumvent the immune responses elicited by vaccination and to alter their virulence levels raises a number of questions concerning the design and use of future vaccines." (4)

Although health authorities such as the FDA and CDC are acutely aware of the numerous studies documenting pertussis vaccine failures in highly vaccinated populations -- due to the imperfect design of current pertussis vaccines which encourage the development of vaccine-resistant mutated strains -- they blame unvaccinated people for outbreaks of the disease. They also insist that nearly everyone must be vaccinated to create a "herd immunity," which would not be possible even if everyone were vaccinated (a 100% vaccine coverage rate), since the vaccine is so poorly effective against circulating strains.

FDA admits: Vaccinated people are spreading disease

There is also another problem with the pertussis vaccine -- it allows vaccinated people to become silent carriers of the disease, spreading it to others. In fact, the FDA recently acknowledged in a press release that individuals vaccinated with an acellular pertussis vaccine "may still become infected with the bacteria without always getting sick and are able to spread infection to others, including young infants who are susceptible to pertussis disease." (5)

The FDA was referencing an important new study published in the Proceedings of the National Academy of Sciences. (6) In this study, infant baboons were vaccinated against pertussis at two, four, and six months of age. At seven months of age, they were exposed to the disease. After 24 hours, unvaccinated baboons were placed in the same cages as the vaccinated baboons. The vaccinated baboons infected them with the disease.

Although the pertussis-vaccinated baboons did not appear sick after being exposed to the disease, the pertussis pathogen, Bordetella pertussis, multiplied and colonized their respiratory systems. The vaccinated baboons were highly infectious and could transmit the disease to other baboons. They had become silent carriers and transmitters of pertussis.

Today, much like Typhoid Mary -- an asymptomatic carrier and transmitter of typhoid fever -- we need to be wary of Pertussis Peggy and Whooping Wally who are circulating pertussis everywhere they go. Thousands of people vaccinated against pertussis could be silent carriers of the disease, spreading it to those who come near.

Outbreaks of pertussis can no longer be blamed on unvaccinated people

This study provides strong evidence that herd immunity is not possible with current acellular pertussis vaccines. In addition, the practice of "cocooning" -- vaccinating people who have contact with infants -- is unlikely to benefit infants, especially when vaccinated people who don't show any symptoms can still spread the disease.

This study also confirmed that the acellular pertussis vaccine induces an immune response inferior to natural infection, and antibody levels induced by vaccination do not correlate with protection against pertussis. (The vaccine increased antibody levels but failed to defend against infection and transmission of the disease.)

In summary, the pertussis vaccine has caused pertussis microorganisms to mutate and become more virulent. People vaccinated against pertussis are able to spread the disease. The pertussis vaccine poses significant risks of irreversible harm. Therefore, no one should be intimidated or coerced into vaccinating against their will. Parents must remain free to accept or reject vaccines for their children.
