We saw in our first  blog on polio that infection with this virus was common, but paralytic polio was rare. In our second  article we reviewed the history of polio and the significant number of cases of paralysis from other causes which were blamed on polio. In the third  article we looked at one of the explanations for the rise of paralytic polio in advanced countries and the collapse of this explanation as polio increased in developing countries.
With polio, is there one cause, the virus, and one effect, paralysis? Obviously not, as the results of infection with the polio virus range from absolutely nothing to death. In this series we are going to review some of the factors which, combined with the presence of the virus, can move the situation from no symptoms and no problems, to paralysis.
A characteristic of infection with polio is the length of time it takes to clear the virus from the body and create immunity to polio.
…the interval between initiation of infection and appearance of CNS signs may be as long as several weeks, which accounts for the great variation in the incubation period of the disease. 
CNS means inflammation of the central nervous system. Someone can be carrying around a happily multiplying polio virus in the nose, throat and gut system, and other non-neural areas of the body, for a period of weeks without having any symptoms to indicate that the virus is there. “Non-symptomatic response” to polio virus exposure, results in eventual clearing of the virus from the system, permanent immunity to that strain of polio, and is the normal bodily response to the polio virus.
However, if something occurs during the several weeks of polio virus carriage which opens up access to the central nervous system to the virus, then the polio moves from asymptomatic to paralytic. There is a list of provokers which cause polio to invade the CNS. Today we are going to consider one cause which we can credit to the medical profession. Read more
Recently we’ve come across multiple examples of local authorities messing with vaccine exemptions. Nothing new, of course, about the media publishing stories which leave out the availability of exemptions when they remind parents of the vaccine “requirements” for school. But there does seem to be something new about counties and school districts coming up with their own paperwork, sometimes in contradiction to state exemption requirements.
For the first time, insidevaccines is asking you to tell us your stories. Has someone given you a hard time when you applied for a vaccine exemption for your kids? Insisted that you need a signature from your pastor? Asked you to sign a form admitting that you are risking the lives of your children and other people’s children? Or?
Comment here, or, if you prefer, send them via e-mail to healthykids@insidevaccines. com
Please share this query on forums and anywhere else you can think of. The more the merrier.
We will not publish anyone’s stories, but we may provide a list of states where problems have arisen and a general description of the types of harassment parents have encountered.
Thanks in advance.

Every August we are hit by a wave of publicity for National Immunization Awareness Month, reminding everyone in the United States to get their children vaccinated, themselves vaccinated, their parents vaccinated, probably even their dogs and cats and goldfish vaccinated.
Vaccinations shouldn’t be that difficult to sell. Who wants their child to die of a communicable disease like mumps? And we all know that influenza kills 36,000 Americans each and every year, because this number is mentioned in just about every news story pushing the influenza vaccine, so it shouldn’t be difficult to convince millions to get their annual flu shot. Except that the Wall Street Journal points out that there are some valid questions about this widely publicized number from the CDC. Even mainstream publications sometimes have questions about diseases and vaccines. Once in a while. Read more
