Abstract
In 1988, the World Health Assembly passed resolution WHA 41.28, which committed the World Health Organization (WHO) to the global eradication of poliomyelitis by the year 2000. In spite of the combined efforts by UNICEF, National Polio Surveillance Project (NPSP), Indian Academy of Pediatrics (IAP) and Rotary International, Polio Free India is still a distant dream. Though oral polio vaccine has succeeded in polio eradication from many countries but there is high incidence of vaccine failure in India. Oral polio vaccine (OPV) has failed to provide full protection to many children who have developed paralytic polio even after taking 10 or more doses of OPV. In some children, OPV has caused paralysis-vaccine associated paralytic polio (VAPP). Number of children developing polio due to vaccine is high and on increase. Reasons for this could be that even immunocompromised children are being administered OPV because IPV is not available. Vaccine failure has exaggerated the problem of VAPP. No efforts have been made to find the causes for high incidence of vaccine failure and VAPP.
