Inadequate immunization among 2-year-old children: a profile of children at risk.

A community survey was conducted to assess the immunization status of 2-year-old children and barriers to immunization. The 299 respondents were more affluent and well-educated than the general population. Eighty-three percent of the respondents received immunizations from private physicians. Only 31.1% of the children were age-appropriately immunized with deficiencies primarily in receiving the 18-month dosages of diphtheria-tetanus-pertussis (DTP) and polio. Parents reported multiple barriers and beliefs about immunization amenable to change by health providers. A profile of risk factors differentiating nonimmunized from immunized children was developed.
