Reasons for partial/non-immunization with oral polio vaccine/triple antigen among children under five years.

To identify the reasons for non-immunization/postponing immunization, parents of 615 poliomyelitis (APM) children and 908 children attending the Outpatient Department (OPD) for other ailments were interviewed. A total of 165 (26.9%), 185 (30.1%) and 264 (43%) among APM and 645 (71%), 183 (20.2%) and 80 (8.8%) among OPD children were immunized, partially immunized and unimmunized, respectively. Forty two per cent and 21% among parents of APM and OPD children, respectively in the unimmunized group were unaware of the need for immunization. The other reasons are minor illnesses, lack of interest, fear of side reaction, non-availability of vaccine or vaccinator. The decision to withhold immunization was mostly by parents when the child had some minor illnesses, mostly respiratory infections. It is recommended to educate the health personnel-clinicians and para-clinical workers by seminar and training and the public through mass media and group contact on the need for and completion of the immunizations.
