| Popis: | Background: In Tamil Nadu India bacille Calmette-Guerin diphtheria-tetanus-pertussis oral poliomyelitis hepatitis B and measles vaccines are part of the routine immunization schedule and are available free from government health centers. All other vaccines are optional and available in the private sector at a cost to families. This study assesses immunization rates of routine and optional vaccines and examines parental attitudes toward vaccines in Pallavapuram Tamil Nadu. Methods: The cluster sampling method was used to estimate immunization coverage. Seven children 18 to 36 months old were selected from 30 clusters for a total sample of 210 children. Demographics and vaccination data were collected from interviews and immunization records. Predictors of vaccination status were identified with logistic regression models. In addition 21 parents participated in semi-structured interviews regarding their attitudes toward vaccination. Interviews were analyzed qualitatively for themes. Results: Eighty one percent of children were fully immunized with routine vaccines. However only 21% received all "major" optional vaccines defined as 3 doses of Haemophilus influenzae type b vaccine one dose of measles mumps rubella vaccine and one dose of varicella zoster virus vaccine. Birth in a private hospital (OR 5.6 95% CI 1.3 to 22.9 P< 0.01) higher income (P= 0.03) and maternal completion of high school (OR 6.4 95% CI 1.5 to 27.6 P< 0.01) were significant predictors of receiving all major optional vaccines. Elucidated themes from interviews included (1) strong parental support for immunizations (2) low concern for side effects and (3) low uptake of optional vaccines due to high cost and lack of awareness. Conclusions: Coverage of optional vaccines is low despite positive attitudes toward immunizations. Efforts to reduce cost and increase awareness of these vaccines particularly among low-income families or to include these vaccines in the routine schedule may increase uptake and reduce morbidity and mortality from vaccine-preventable diseases. |
