in vivo mutation of B. Pertussis ?

[Fièvre]

In a WHO document - quite old : 1974- and , sorry, in French , it is written (http://whqlibdoc.who.int/HQ/pre-wholis/WHO_BAC_75.1_fre.pdf ) :

"On a noté que les mutations se produisent in vivo chez l'enfant et chez le ouistiti d'expérience , et certains faits,cités par des participants , donnent à penser que, chez les enfants ou les animaux mal vaccinés, ces mutations ou glissement vont dans le sens d'une transformation permettant au germe d'échapper à l'effet immunitaire du vaccin "

grossly translated in "genetic mutation occured in vivo in kids and marmosets - unappropriatly vaccinated- that led them not to be immune "

Have you encountered similar - and more recent - info concerning these mutations ?

By the way : i can't find an overall info on B. Pertussis serotypes : in the above cited text serotypes 1,2,3 are cited : when were they identified...

Yes, there's a whole raft of stuff on it, since then. Try Pubmed. The WHO article is crap. The fact is that vaccinated children's bodys are the ones which change the pertussis bacteria, not vaccinated.

There's even on from where you come from:

There's a lot more at the same website http://jcm.asm.org/cgi/content/full/47/3/680

You can use the bottom lists of where this article was cited to see who else might be talking about it:
