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 cent get Paralytic disease, has continued to occur in immunized person with salk vaccine. The immunity produced by live oral Poliovivus Vaccine appears to be as good as after natural infection. The oral vaccine is capable of pro­ducing both serologic and somatic (intestinal) immunity, this has a great importance to eleminate the vivus from a given population or to stop an epidemy of poliomgelitis by routine and massive oral vaccination. Oral Polio Vaccine is given in three doses, one or two months apart, in the non-Polio seasons it ean be given at the time of D.P.T. immuniza­tion, the 1st booster is usually given 6 - 12 months later and then few other doses are given till the age of 6 years old.
