Hypothesis
Does improving maternal knowledge of vaccines impact infant immunization rates?
Conclusion
A simple educational intervention designed for low-literate populations improved DPT-3/Hepatitis B vaccine completion rates by 39%.
Supporting Evidence
- 129 (72.1%) infants in the intervention group received all 3 doses of DPT/Hepatitis B vaccine.
- 92 (51.7%) infants in the control group received all 3 doses.
- The intervention improved DPT-3/Hepatitis B immunization rates by 39%.
- Vaccination cards were retained by 81% of participants in the intervention group.
Takeaway
Teaching mothers about vaccines helps more babies get their shots.
Methodology
Randomized controlled trial with 366 mother-infant pairs receiving either an educational intervention or general health promotion messages.
Potential Biases
Potential misclassification bias due to reliance on vaccination cards for proof of immunization.
Limitations
High refusal rate (27%) and lack of blinding for participants and CHWs.
Participant Demographics
Mothers living in low-income, low-literacy communities in Karachi, Pakistan.
