It is the government itself, slashing and burning trust and faith that is doing most of the damage to vaccination programs:
The Tuskegee syphilis experiment was an infamous clinical study conducted between 1932 and 1972 by the U.S. Public Health Service to study the natural progression of untreated syphilis in rural African American men who thought they were receiving free health care from the U.S. government.
Few mourn the man responsible for the slaughter of many thousands of innocent people worldwide over the years. But the operation that led to his death may yet kill hundreds of thousands more. In its zeal to identify bin Laden or his family, he CIA used a sham hepatitis B vaccination project to collect DNA in the neighborhood where he was hiding. The effort apparently failed, but the violation of trust threatens to set back global public health efforts by decades.
I'll let the rest of you decide where you think a national registry coupled with the laws of unintended consequences and human nature are bound to lead such a project.
