“In about 1 case per 3 million, the vaccine virus can itself cause paralysis. (A current theory is that paralysis results in recipients with existing immune deficiencies.) This risk, while devastating, is “accepted” by administering agencies as a necessary cost of saving “hundreds of thousands” of children each year from crippling.”

A Google search led me to the website http://www.immunizationinfo.org/vaccines/polio , which is supported by the National Network for Immunization Information, a nonprofit organization based in Texas that is recognized by WHO.

Quotes from the source:

“The oral polio vaccine (OPV) is no longer administered in the U.S.

…

However, about 1 out of 2.4 million doses of OPV distributed in the United States actually caused vaccine-associated paralytic polio (VAPP). In an effort to reduce this terrible side effect, a new polio vaccine schedule was recommended in 1997 (two doses of IPV followed by two doses of OPV). The new schedule decreased, but did not guarantee elimination, of vaccine-induced paralytic polio; so, effective in the year 2000, an all-IPV schedule was recommended, and OPV is no longer administered in the U.S. OPV continues to be used in countries where wild polio infections still occur.

…

OPV causes vaccine associated paralytic polio in a very small percentage of those immunized. It is more likely to occur in those with weakened immune systems. IPV cannot cause paralysis, as the vaccine virus has been inactivated.”

This information puts a new spin on the question of whether to force innoculations to be rid of Polio. Without this information, the argument in the paper is along the lines of “the only way to remove the threat of polio is to use the method that causes 1 in 2.4 million people to become paralyzed.” But with this information, the argument shifts to “We’re only prepared to spend the money to eradicate polio in a way that leaves 1 in 2.4 million people paralyzed, as opposed to a way to eradicate polio with no side effects.”This is a radical change, especially considering that in the U.S. (and presumably other more developed countries) the safe IPV method is used.
