I will be watching this thread, as this is something I am very interested in.
My DD has not yet had the chance to gain natural immunity to CP (unlike her brother) and I really prefer that she DO before adulthood.
BUT, I also am dubious about the vaccine strain virus as opposed to the wild virus.
There is so much emerging info on the CP vax and negative effects, from waning immunity to breakthrough (contagious) infections in the vaxed to erosion of natural immunity.
I have research a LOT on this illness and the vaccine, but this issue, the issue of differences, if any, between the vax strain and the wild virus is not one I have found anything on.
I assume there may be differences, if only because of the evidence to date indicates that the naturally immune are losing immunity due to a lack of exposure to the virus YET it also indicates that breakthrough/contagious cases in the vaxed are widespread. So what gives??? If there is still such widespread chance of exposure due to so many being vaxed with the live virus, WHY is natural immunity NOT being boosted by these exposures as it was from exposures to the wild virus??
A conundrum I have yet to unravel.
Any help is appreciated
