AT a meeting of the Committee held in Toronto on October 22, 1951, the evidence associating immunization procedures with paralytic poliomyelitis was reviewed. The information (published and unpublished) which is available at present is insufficient to conclude whether injections of vaccine and/or toxoid, and also possibly smallpox vaccination, predispose to paralytic poliomyelitis. The members of this Committee therefore are not able to alter the views expressed in their report of May 1951 which was published in the recent (1951) edition of the Red Book (page 2, paragraph 3 and page 50, paragraph 7). However, as there have been numerous requests for amplification of these views, the following recommendations are submitted:
It is recommended that immunization procedures be not discontinued on a seasonal basis in anticipation of an epidemic. When, however, an outbreak of poliomyelitis of considerable proportion occurs in one's community, then elective immunization procedures in individuals over the age of six months should be deferred. Elective procedures are considered to be (1) primary and routine recall injections of tetanus toxoid, (2) primary and routine recall injections of diphtheria toxoid, pertussis vaccine, and typhoid vaccine in the absence of existing diphtheria, pertussis, and typhoid, respectively, in the community, and (3) primary smallpox vaccination and revaccination in the absence of any cases of smallpox. If outbreaks of any of these diseases coexist in the community with an outbreak of poliomyelitis the above immunization procedures would cease to be elective and should be performed: that is, unprotected children should be given their primary immunization and previously immunized children should receive a recall injection of the appropriate antigen.
