The bacterium that causes whooping cough,
Bordetella pertussis, has changed in Australia -- 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.

A UNSW-led team of researchers analyzed strains of
Bordetella pertussis from across Australia and found that many strains no longer produce a key surface protein called pertactin.
About 80 per cent of the 2012 whooping cough cases in Australia studied by the team were caused by pertactin-free strains. Pertactin is one of the three proteins, made from purified extracts of
Bordetella pertussis bacteria, which are present in the vaccine currently used in Australia. The other two are pertussis toxin and filamentous haemagglutinin.
"
It's like a game of hide and seek. It is harder for the antibodies made by the body's immune system in response to vaccination to 'search and destroy' the whooping cough bacteria which lack pertactin," says the senior author of the study, Associate Professor Ruiting Lan, of the UNSW School of Biotechnology and Biomolecular Sciences.
"This could mean that these pertactin-free strains have gained a selective advantage over bacterial strains with the pertactin protein."
The study is published in the journal
Emerging Infectious Diseases.
Australia has only recently emerged from
an epidemic of whooping cough that went on for an unusually long period -- with about 142,000 cases from 2008 to 2012. Although the number of cases identified was greatly increased by more and better testing, the epidemic was still a major one. Nine babies died of whooping cough during the five years.
The research, led by UNSW PhD student Connie Lam, involved the analysis of 320 bacteria samples from patients with whooping cough obtained during 2008-2012 from five states -- NSW, Victoria, Queensland, South Australia and Western Australia.
The proportion of pertactin-free bacteria rose from five per cent of cases tested in 2008 to 78 per cent in 2012. Pertactin-free strains of pertussis
have also been detected overseas, including in countries such as France and the United States."
The fact that they have arisen independently in different countries suggests this is in response to the vaccine," says Associate Professor Lan.
There is no evidence that the pertactin-free strains are more harmful than other strains, and it is not yet clear whether they reduce the effectiveness of the vaccine in the short or long term.
"More studies are needed to better understand the effects of vaccination on the evolution of the organism," says Associate Professor Lan.
The current acellular vaccine, purified down to three antigens, was introduced in 1997 to replace the previous whole-cell vaccine, after side effects such as fever and crying dissuaded many parents from starting or completing the three doses of vaccine required by six months of age.
"The acellular pertussis vaccine produces antibodies against pertussis toxin which is the main cause of severe disease symptoms produced by the whooping cough bacterium. Vaccination is still the only way to protect against whooping cough, especially for the youngest babies who are most at risk of severe illness," stressed Associate Professor Lan.
Babies need to be immunized at six to eight weeks of age, four months and six months, with a booster at four years.
Comment: This is completely mind boggling: Despite the fact that vaccination made things only worse, the cognitive dissonance is such that they still recommend the vaccine.

Deaths from Pertussis
In the
United States from 2012 to 2013 there were over 72,508 reported cases
including 9 reported deaths (all infants under 3 months old.) Of the reported cases of pertussis only 635 victims were confirmed as unvaccinated. In England and Wales
about 5 deaths per year are recorded.
Source >>Pertussis Vaccine Reactions
According to the
US VAERS, as of the 1st of April, 2012, there were 130,448 reactions reported to a vaccine containing either diphtheria, tetanus or
pertussis toxin (pertussis vaccine is usually delivered as a DPT or other multi-vaccine injection) 2,464 of these involved life-threatening reactions of which
2,333 of the children or adults died. 11,498 of those who were reported as reacting to this vaccine had not recovered at the time of the report and may have had life-long-disabilities as a result. VAERS uses a 'passive' adverse reaction reporting system which means that they admit to only collecting between 1 and 10% of all reactions. Therefore, the figures above are likely to represent only a small percentage of the actual damage caused by these vaccines.

I have 2 young children who will never have any of those vile concoctions. They are both very healthy and intelligent and i can't understand how anyone would wiilingly poison their own children because someone with a white coat and some letters after their name says so.... crazy world
