Very interesting indeed! Especially since Phil Minor documented several
years ago that neurovirulent revertants of attenuated vaccine strains
could be isolated out of the feces of immunized babies 24-72 hours
post-inoculation. I thought that I had heard of cases some three or four
years ago of cases where non-immunized grandparents had been infected by
newly immunized babies and had successfully sued the physicians on the
