Navigating Pakistan's immunization landscape: Progress and pitfalls.

Objectives: This study aims to assess the impact of the 2022 floods in Pakistan on the incidence of vaccine-preventable diseases (VPDs) in flood-affected regions, specifically focusing on areas with traditionally low vaccination coverage.

Design: Weekly incidence data of VPDs from September to November 2021 and 2022 were collected and analyzed for the provinces of Sindh, Khyber Pakhtunkhwa, and Baluchistan. The study compared year-on-year changes in disease incidence to evaluate the effect of the floods on disease burden.
