Implications of COVID-19 and "super floods" for routine vaccination in Pakistan: The reemergence of vaccine preventable-diseases such as polio and measles.

With multiple waves and variants, the coronavirus disease 2019 (COVID-19) pandemic has affected routine vaccination programs globally. Its impact is also visible in Pakistan as routine health services continue to be disrupted. Consequently, thousands of children have emerged as vulnerable in the face of vaccine-preventable diseases (VPDs), which have already started causing outbreaks in the country. Infections with polio and measles have been significantly reported, especially during the last few years. This reemergence of both diseases is posing great challenges for the country at local, national, and global levels. These impacts are being multiplied by the 2022 flooding - called "super floods" - in the country. Hence, relevant stakeholders, such as the Pakistani government and the World Health Organization (WHO), need to revisit the entire vaccination program to address and resolve issues occurring at the management or local levels. It is highly important to pay attention to the context that provides a fertile ground to negatively affect vaccine uptake.
