A free mass dog vaccination campaign in Techiman South Metropolitan, Ghana, has achieved an estimated 70 percent coverage of the city’s dog population, meeting the internationally recommended threshold needed to interrupt rabies transmission, according to a new evaluation published in PLOS Neglected Tropical Diseases. The campaign, coordinated under a One Health framework and carried out in September 2024, offers one of the few detailed operational assessments of a municipal-level dog vaccination effort in a rapidly urbanizing, resource-constrained setting in Sub-Saharan Africa. Its findings carry weight far beyond Techiman, because rabies still kills an estimated tens of thousands of people each year worldwide, with the overwhelming majority of human cases linked to bites from infected dogs.
The evaluation team, led by Prince Kyere Dwaah of institutions in Ghana, conducted a mixed-methods post-campaign assessment two weeks after the vaccination drive ended. The design combined quantitative and qualitative strands. Quantitative data came from structured questionnaires administered to 200 dog-owning households, alongside a review of administrative vaccination records used to estimate overall coverage. Qualitative data came from key informant interviews with the people who actually delivered the campaign: veterinary officers, public health professionals, environmental health personnel, and community leaders. Descriptive statistics summarized household participation and awareness indicators, while the interview material was analyzed thematically to identify what helped and what hindered implementation.
The household survey revealed important details about the structure of dog ownership in Techiman. Among the surveyed households, 59.5 percent owned more than one dog, a pattern that matters for campaign planning because multi-dog households can amplify both transmission risk and the logistical burden of reaching every animal. Just over half of the households, 51.5 percent, reported vaccinating at least one dog during the campaign. That figure, while substantial, also signals that nearly half of the dog-owning households surveyed did not participate, a gap the authors link to the operational barriers documented elsewhere in the study.
Perhaps the most striking results concern rabies knowledge. Awareness that rabies is fatal rose from 45 percent, based on self-reported recall of pre-campaign knowledge, to 75 percent after the campaign period. Awareness that rabies is preventable increased from 40 percent to 70 percent. These are self-reported figures and therefore subject to recall and social desirability biases, but the magnitude of the shifts suggests that the campaign’s public communication component, including mobilization around World Rabies Day, reached a large share of the community. Because demand for vaccination depends heavily on owners understanding the stakes, this knowledge gain is not merely a soft outcome; it is a structural ingredient of coverage.
On the supply side, administrative records indicated that approximately 5,600 dogs were vaccinated during the campaign. When set against projected dog population figures for the metropolitan area, this corresponds to an estimated 70 percent coverage, exactly the threshold that the World Health Organization and partner agencies have long identified as necessary to break the transmission cycle of canine rabies. The technical logic behind that threshold is rooted in the basic reproduction number of rabies in dog populations: if a sufficiently large fraction of dogs is immune at any given time, each infectious dog fails to transmit the virus onward often enough to sustain the epidemic, and the pathogen dies out locally. Sustaining that level year after year, however, is considerably harder than reaching it once.
The evaluation was careful to distinguish administrative coverage from effective population immunity. Administrative figures count doses delivered at fixed points and outreach stations, but they can overstate true immunity if dogs are missed unevenly across neighborhoods, if records are incomplete, or if free-roaming animals are systematically excluded. In Techiman, the qualitative interviews surfaced precisely such concerns. Participants identified strong multisectoral collaboration and World Rabies Day mobilization as key facilitators of the campaign, evidence that the One Health approach, which deliberately links human, animal, and environmental health sectors, can translate into concrete operational gains when it is built into campaign design from the start.
Against those facilitators stood a set of persistent barriers that the authors argue could undermine effective immunity even when headline coverage looks adequate. Vaccine supply delays disrupted planning and delivery. Cold-chain capacity was limited, a critical weakness because rabies vaccines are thermolabile; if the cold chain breaks, doses may lose potency before they are injected, silently eroding protection. Access was inadequate for peri-urban communities, the fast-growing fringe zones where dog populations are often dense and veterinary services thin. And the campaign lacked strategies for vaccinating free-roaming dogs, a population that fixed-point vaccination inherently struggles to reach because unowned and loosely owned animals rarely present themselves at posts. In many African cities, free-roaming dogs make up a substantial share of the total population, so their exclusion can leave a reservoir of susceptible animals even in a nominally well-covered district.
These findings sit within a broader and well-documented pattern across Sub-Saharan Africa, where mass dog vaccination programmes are frequently constrained not by the complete unavailability of vaccines but by inconsistent procurement, financing limitations, cold-chain requirements, and weaknesses in distribution systems. The Techiman study contributes operational evidence from a municipal campaign, a scale that has been underrepresented in the literature compared with national programme reviews or small pilot projects. Rapidly urbanizing cities like Techiman present a distinctive epidemiological profile: growing human populations, expanding peri-urban settlements, dense dog ownership, and health infrastructure stretched across jurisdictional boundaries. Campaign models that work in rural districts may not transfer cleanly to such settings, which is why locally grounded evaluations like this one matter for regional policy.
The authors draw a set of practical conclusions for future campaigns. Vaccine logistics need strengthening, with procurement timed to avoid delays and cold-chain capacity expanded so that potency is preserved from warehouse to injection site. Access for peri-urban communities must be deliberately engineered, for example through satellite stations or mobile teams rather than relying on owners to travel to central points. Monitoring systems should be improved so that coverage estimates can be validated against independent surveys rather than resting solely on administrative counts. Most consequentially, campaigns need to incorporate explicit strategies for free-roaming dogs, which may include catch-vaccinate-release operations, community-based dog population management, and incentives that bring loosely owned animals within reach of vaccinators.
The significance of the Techiman evaluation extends to the global goal of eliminating dog-mediated human rabies deaths, a target that international agencies have set for 2030 under the framework Zero by 30. The arithmetic of that goal is unforgiving: every endemic country must reach and sustain at least 70 percent dog vaccination coverage, year after year, in every district. Techiman shows that a resource-constrained African municipality can hit the threshold in a single campaign when sectors collaborate and communities are mobilized. It equally shows that hitting the number once is not the same as controlling the disease, and that the unglamorous machinery of supply chains, cold boxes, peri-urban outreach, and free-roaming dog strategies will determine whether campaigns like this one become the beginning of elimination or a one-off success. The evaluation’s message to programme planners is therefore twofold: celebrate the 70 percent, then get back to work on the barriers that stand between a vaccinated record and a protected population.
