The Epidemiology of poliomgelitis has been investigated in our country Pasteur Institute; the incidence of Poliomgelitis, after the age of 4 years i's rare, in Iran.  Passive antibody of maternal origin do not interfere with production of active antibody after immunization.  Inactivated Polio Vaccine (salk) has been effective in reducing the incidence of poliomge­litis by approximately 90 per ...

TIIE BIGGEST PUBLIC IIEALTH EXPERIMENT EVER: The 1954 Field Trial of the Salk Poliomyelitis Vaccine

THE LARGEST and most expensive medical experiment in history was carried out in 1954. Well over a million young children participated, and the immediate direct costs were over 5 million dollars. The experiment was carried out to assess the effectiveness, if any, of the Salk vaccine as a protection against paralysis or death from poliomyelitis. The study was elaborate in many respects, most prom...

Vaccine-associated paralytic poliomyelitis.

In the wake of the World Health Organization’s (WHO) program to eradicate poliomyelitis globally by the end of the year 2000 (in 1997 only 5,186 cases were reported world-wide), attention has focussed on the importance of good surveillance of acute flaccid paralysis, which is essential for a country to qualify for being declared polio-free, and on the occurrence of vaccine–associated paralytic ...

Vaccine control of poliomyelitis in the 1980s.

The main challenge of vaccine control of poliomyelitis in the 1980s is in the subtropical and tropical regions of the world where "lameness" surveys in recent years have shown how very high the average annual incidence of paralytic poliomyelitis can be in both rural and urban areas in the absence of epidemics. The procedures by which oral polio vaccine (OPV) rapidly eliminated all or almost all...
