No, I still think that it mutates because that's what the CDC say. It's right there in black and white. It says, and I quote, again:
'We discuss changes in the ecology of B. pertussis that may have driven this adaptation. Our results underline the importance of Ptx in transmission, suggest that vaccination may select for increased virulence, and indicate ways to control pertussis more effectively.'
I.e They are discussing changes that drove the adaption (mutation) of pertussis. Vaccination may be causing INCREASED VIRUALENCE of pertussis.'
And in 2nd source:
An acellular whooping cough vaccine actually enhances the colonization of Bordetella parapertussis in mice; pointing towards a rise in B. parapertussis incidence resulting from acellular vaccination, which may have contributed to the observed increase in whooping cough over the last decade.
I.e. The vaccine ENHANCES the growth of parapertussis and the rise in cases is due to the vaccine.
The full study on the rats, that showed a 40 fold increase in parapertussis, is here:
'Directly proving aP vaccination puts treated people at risk of acquiring B. parapertussis is very difficult, but we hope our study highlights the need for more thorough B. parapertussis epidemiological data and encourages further work in this neglected area. If our experiments are capturing the phenomenology of what is happening under aP vaccination in humans, it may be important to consider the introduction of vaccines that better protect against both bordetellae.
We note that epidemiological evidence in human whooping cough infections is consistent with an enhancement effect for B. parapertussis (Bergfors et al. 1999; Liese et al. 2003).
An enhanced understanding of the evolutionary consequences of widespread aP vaccination is needed in order to optimize the next generation of vaccination strategies and fully reap the benefits of this powerful medical intervention.'
The evolutionary consequences meaning mutation, just like bacteria have evolved to beat antibiotics.
And this newspaper article says that whooping cough has mutated:
Of course they do the usual and blame parents who don't vaccinate but if they looked at the above study I just showed you, they would see that's it's vaccination that caused the 40 fold increase in mutated pertussis.
This article on a poultry vaccine says the same thing, that vaccination is causing the formation of new genotypes of disease:
'Collectively, these data show that vaccination with live attenuated viruses has changed the evolution of aPMV-1 by maintaining a large effective population size of a vaccine-related genotype, allowing for coinfection and recombination of vaccine and wild type strains, and by applying unique selective pressures on viral glycoproteins.'
Re-combination is mutation, the vaccine viruses mixing with other viruses and making a new virus.
I think that may be why we are now seeing new strains of measles:
Nineteen distinct measles virus (MV) strains associated with nine different genotypes were identified in five Australian states (Victoria, New South Wales, Queensland, Northern Territory and Western Australia) between 1999 and 2001. One of the strains identified is likely to represent a new genotype within the clade D viruses (proposed to be d9). No evidence for an indigenous MV strain was found. When epidemiologic information associated with the index case was available for the outbreaks, it usually supported introduction of the virus from overseas, with the main source being South East Asia. Changes in the circulation of MV in Australia since the early 1970s were also observed. Prior to the introduction of measles vaccine, the majority of the population acquired immunity through infection with wild-type virus in early childhood. Nowadays in Australia, young adults are at most risk of infection.' (As a side note to this, measles is more serious in adulthood).
And here's another news article on the old prevenar 7 vaccine causing 'superbug ear infection' -
This is what happens, they can't deny it because they said so and it's in their research.
I'm not changing the subject at all, just making conversation :)
