Comprehensive Outreach: Reach Every Child Initiative Expanded Program on Immunization Khyber Pakhtunkhwa, Pakistan

Abstract

Background: Vaccination is one of the most effective public health interventions for preventing infectious diseases. In regions like Khyber Pakhtunkhwa, Pakistan, where access to healthcare is limited, immunization coverage often remains below optimal levels. Targeted outreach activities can play a pivotal role in improving vaccine uptake, particularly in underserved populations. Objective: This study aimed to assess the effectiveness of immunization outreach activities in increasing vaccine coverage in Khyber Pakhtunkhwa over a defined period. Methods: A comprehensive methodological approach was utilized involving predefined Excel sheets for daily data collection by trained personnel. Data validation procedures were implemented to ensure accuracy, with regular feedback sessions to improve data collection processes. Monthly reports were compiled and analyzed using SPSS version 25 to summarize immunization activities and coverage rates. The outreach strategy included community announcements and door-to-door campaigns by Local Health Workers (LHWs), designed to identify and vaccinate zero-dose and defaulting children. Results: The outreach campaign significantly improved immunization coverage, with zero-dose vaccinations achieving 100% coverage. Penta I, II, and III vaccines saw coverage rates of 78.99%, 72.48%, and 78.02%, respectively. Measles vaccines MCV-I and MCV-II achieved coverage rates of 83.01% and 86.11%. The overall strategy effectively reduced gaps in vaccine coverage across various districts. Conclusion: The study confirms that structured and well-coordinated outreach activities can effectively increase immunization coverage in areas with limited healthcare access. Continuous effort and strategic planning are essential to sustain and build upon these gains to ensure comprehensive vaccine coverage.
