A dog vaccination campaign in Techiman South Metropolitan, Ghana, has reached an estimated 70% coverage of the city's dog population, achieving the World Health Organization's recommended threshold necessary to interrupt rabies transmission, according to a report in PLOS Neglected Tropical Diseases. Conducted in September 2024, the initiative was part of a One Health framework and provides valuable insights into municipal-level vaccination efforts in resource-constrained environments in Sub-Saharan Africa. Rabies continues to be a significant public health concern, causing the deaths of tens of thousands globally each year, with the majority of cases associated with infected dogs.

The evaluation team, led by Prince Kyere Dwaah, undertook a mixed-methods assessment two weeks post-campaign, incorporating both quantitative and qualitative approaches. They surveyed 200 dog-owning households, coupled with an analysis of vaccination records. This quantitative data was complemented by thematic interviews with campaign deliverers, including veterinary officers and public health professionals, to identify both facilitators and hindrances to the campaign.
The survey revealed that 59.5% of households owned multiple dogs, which can complicate vaccination logistics. While 51.5% reported vaccinating at least one dog during the campaign, this indicates that nearly half of the dog-owning households did not participate, suggesting operational barriers tied to the study's findings. Notably, awareness of rabies' fatal nature increased from 45% pre-campaign to 75% post-campaign, while understanding of its preventability rose from 40% to 70%. These shifts demonstrate the effectiveness of the campaign's communication efforts, particularly those surrounding World Rabies Day.
Approximately 5,600 dogs were vaccinated during the campaign, aligning with projections that indicate 70% coverage needed to disrupt rabies transmission. However, the study emphasized the distinction between administrative coverage and effective immunity, highlighting concerns that uneven vaccination across neighborhoods and exclusion of free-roaming dogs could undermine true immunity rates.
Participants in the qualitative interviews recognized strong collaboration and World Rabies Day initiatives as key success factors, illustrating the potential of the One Health approach to yield real operational benefits when integrated into campaign planning from the outset. Nevertheless, challenges persisted, such as supply delays, inadequate cold-chain capacity, and inadequate access in peri-urban areas, complicating the campaign's implementation.
The findings underscore a widespread issue in Sub-Saharan Africa where vaccination programs often face constraints not due to vaccine unavailability but rather due to systemic challenges in procurement, financing, and distribution. The Techiman study fills a gap in the literature concerning municipal vaccination campaigns, which are often less represented compared to national reviews or pilot projects. It highlights that urban environments like Techiman have distinct epidemiological profiles that require tailored campaign models.
The authors recommend enhancements for future vaccination campaigns, including improved vaccine logistics, better access for peri-urban communities, and explicit strategies for vaccinating free-roaming dogs. These suggestions aim to ensure sustained coverage and effective immunity.
The evaluation's findings contribute to a broader global objective of eliminating dog-mediated human rabies deaths, with a target set for 2030 under the Zero by 30 framework. Achieving and maintaining at least 70% vaccination coverage year-round in all districts is crucial. The Techiman campaign exemplifies how, with appropriate sector collaboration and community engagement, a resource-limited municipality can achieve this milestone. However, it also highlights the necessity of ongoing efforts to address remaining barriers to ensure lasting protection against rabies.
