Key takeaway Through four nationwide vaccination campaigns, strengthened surveillance, and enhanced outbreak response measures, no cVDPV2 has been detected in the country since June 2024.
Why this matters
Zimbabwe's participation in the synchronized subregional vaccination effort is crucial in maintaining the country's progress in interrupting poliovirus transmission. The fact that no cVDPV2 has been detected in Zimbabwe since June 2024 is a significant achievement, but the ongoing outbreaks in neighboring countries pose a persistent risk of cross-border virus importation. The coordinated regional response, involving multiple countries and partners, highlights the importance of collaboration in preventing the re-emergence of polio. The deployment of national surge consultants and the mobilization of over 6,000 personnel demonstrate the scale and complexity of the effort required to sustain high population immunity. By targeting high-risk districts and using door-to-door vaccination, the campaign aims to reach vulnerable children who might otherwise be missed, reducing the risk of poliovirus transmission and protecting the gains made so far. This approach will be critical in maintaining Zimbabwe's polio-free status and ultimately achieving regional immunity.
