I had whooping cough a few years back, as did my elderly (don't tell her I said that) mother, my son was obviously exposed but didn't catch it. It may have been a mild case, but I don't see why it is not manageable for the healthy population. Yeah, it sucked...yes every time I coughed my eyes felt like they were gonna pop out of my head...yeah it hurt...but it was manageable. You get stronger and more resilient strains of any virus/infection/disease when you start combining it with other substances (both natural and man made).
It kind of goes along the lines of the chicken pox vaccine. I had the CP as a kid, all my siblings had it as kids, everyone I know had it as kids...we survived just fine, we got itchy red spots all over and ended up with an immunity that lasts to it. Now they are coming out with the vaccine for it, it's on the rise (one case in a school is now considered an outbreak

)...and older people, who trust their doctors, are getting the vaccine, thus bringing on outbreaks in the herpes virus and resulting in more resilient strains and killing people.
I'm sure you see where I am going with this, this vaccine is being pushed, cases are on the rise...maybe not because of poverty and it just making its rounds, but because they are introducing it to the population again, and more than likely in a stronger form, or mutated form, because of anything it is mixed with. Our bodies are made to build immunities over time, not to be assaulted by dozens at a time and more than likely mutated versions of it because some scientist decided to mix it with 10 others things that shouldn't be in there to begin with.
