Change in polio vaccine policy eliminates cases of vaccine-associated polio in US

A change in the national polio vaccination policy has led to the elimination of vaccine-associated paralytic poliomyelitis (VAPP), according to a study in the October 13 issue of JAMA.

According to background information in the article, the last case of poliomyelitis (polio) in the United States caused by a naturally occurring virus occurred in 1979; however, as a consequence of oral poliovirus vaccine (OPV) use that began in 1961, an average of 9 cases of VAPP were confirmed each year from 1961 through 1989. To reduce the VAPP burden, national vaccination policy changed in 1997 from reliance on OPV to options for a schedule of inactivated poliovirus vaccine (IPV) followed by OPV. In 2000, an exclusive IPV schedule was adopted.

Lorraine Nino Alexander, M.P.H., of the Centers for Disease Control and Prevention, Atlanta, and colleagues reviewed national polio surveillance data in the United States from 1990 through 2003, examining the epidemiology of polio and assessing the association between the vaccine schedule changes and VAPP in the United States.

The researchers found that from 1990 through 1999, 61 cases of paralytic polio were reported; 59 (97 percent) of these were VAPP (1 case per 2.9 million OPV doses distributed), 1 case was imported, and 1 case was indeterminate. Thirteen cases occurred during the 1997-1999 transitional policy period and were associated with the all-OPV schedule; none occurred with the IPV-OPV schedule. No cases occurred after the U. S. implemented the all-IPV policy in 2000. The last imported polio case occurred in 1993 and the last case of VAPP occurred in 1999.

"Following this change, all forms of poliomyelitis have been eliminated in the United States," the authors write. "The only threats from polio in the United States are from laboratories and the few remaining polio-endemic areas in Africa and Asia."

"Elimination of VAPP is an important public health accomplishment in the United Stat
