In his argument supporting the Advisory Committee on Immunization Practices-recommended switch to a sequential inactivated polio vaccine/oral polio vaccine (IPV/OPV) immunization schedule (Pediatrics. 1996;98:116-117), Dr Samuel Katz fails to address the enormity of the threat that an untested immunization practice poses to an unprepared public.
Dr Katz theorizes that the proposed sequential schedule may reduce the six to eight cases of vaccine-associated paralytic polio that occur each year. Yet no solid proof exists to support this claim.
