Implementation fidelity of rabies vaccination campaigns determines whether proven vaccines prevent human cases in the real world. A PLOS study of the September 2021 campaign in southern Cercado, Cochabamba evaluated 17 health centers and interviewed 46 providers and 108 pet owners; none of the centers met the 80% adherence threshold (published July 10, 2026). This post shows how structured fidelity checklists plus CFIR-guided qualitative diagnosis can prioritize repairs to cold chain, staffing, coordination, and communication.

Key Takeaways
The Cochabamba evaluation shows that implementation failure, not vaccine efficacy, explains persistent canine rabies in this setting; fix cold chain, staffing, coordination, and communication to improve campaign outcomes.
A 27-item fidelity checklist mapped to Carroll constructs, triangulated with CFIR qualitative analysis, allows program teams to prioritize low-cost, high-impact operational fixes quickly.
- The primary study was published in PLOS NTD on July 10, 2026 and evaluated the September 2021 campaign in southern Cercado, Cochabamba.
- Across 17 health centers, 12 (70.6%) met vaccine availability but no center achieved ≥80% content adherence; content scores ranged 32%–79%.
- Cold chain risks were widespread, with 76.5% of centers lacking refrigerators, and 88.2% of centers had incomplete brigades, identifying clear operational priorities.
Fast take + source
The quick summary: A mixed-methods implementation-fidelity assessment of the September 2021 dog and cat vaccination campaign in southern Cercado (Cochabamba) found pervasive operational gaps (cold chain failures, incomplete brigades, fragmented coordination) and quantified them across 17 first-level health centers.

What happened: methods and key fidelity gaps
The study used Carroll’s fidelity framework and CFIR to identify where fidelity failed and why it failed in this campaign.
The study used Carroll’s fidelity framework (content, coverage, frequency, duration) and CFIR for qualitative explanation. A 27-item checklist coded items YES/NO by documentary evidence; interviews followed COREQ guidance.
- No health center met ≥80% adherence on content; content scores ranged 32–79%.
- 12/17 centers (70.6%) met vaccine availability and postcampaign continuity; 5 centers failed postcampaign continuity.
- Frequency was largely adequate (14/17, 82.4%), but only 4/17 centers promoted campaigns ≥1 month in advance.
- Cold chain, staffing (missing channelers/registry staff), damaged coolers, and fragmented ETD–OTB coordination were the dominant barriers identified by CFIR analysis.
So what for program teams and researchers
Program managers
Program managers should prioritize low-cost, high-impact operational fixes: repair or replace coolers, preposition insulated carriers, and implement thermotolerant vaccine options where feasible.
Formalize ETD–OTB agreements and standardize one-month advance messaging in Spanish and Quechua.
Implementation researchers
Implementation researchers should use Carroll plus CFIR in parallel to map where fidelity fails to why it fails and to guide remediation studies.
Replicate the 27-item checklist as a binary audit or adapt to a graded scale for sensitivity analyses and triangulate checklist scores with interview themes and WhatsApp coordination logs to locate actionable bottlenecks.
UX/Behavioral teams
UX and behavioral teams should target messaging to address pet-keeping norms and caregiver availability constraints that reduce access.
Pilot evening or weekend posts and school-based prompts, and segment communication by language (Spanish and Quechua) and micro-territory to improve reach.

Platform definition
Evidano is an AI-powered qualitative data analysis platform that ingests transcripts, checklists, registries, and documents to accelerate implementation diagnosis and create traceable evidence.
Evidano ingests mixed formats and links them to checklist items for traceable evidence across documents and transcripts.
Problem: fragmented documents and noisy transcripts → Solution: unified ingestion
Ingest the 27-item checklist, vaccination registries, meeting minutes, and interview transcripts into the platform to create a unified, searchable evidence base.
Evidano ingests mixed formats and links them to checklist items for traceable evidence.
Problem: slow qualitative synthesis → Solution: thematic + frequency analysis
Run automated CFIR-aligned theme extraction to surface the top barriers and their frequencies by center so teams can prioritize interventions.
Evidano reports theme frequency and cross-tabulates themes by health center, enabling prioritized, center-level interventions.
Problem: multilingual field notes and PII risk → Solution: transcription, translation, redaction
Use the platform's transcription with custom dictionaries for Quechua and Spanish and apply PII redaction before analysis to protect participant privacy.
Translate participant quotes conservatively while preserving original phrasing for stakeholder reports.
Problem: stakeholders need persuasive visuals → Solution: visual analytics
Generate word clouds, co-occurrence networks, and hierarchical code→subcode trees to show how operational issues cluster by health center and by theme.
Visual analytics help stakeholders see clusters such as 'cooler' linked to 'cold chain' and 'broken', making the case for targeted repairs.
Problem: needing follow-ups → Solution: AI avatar interviews & chat
Deploy AI avatar-based follow-up interviews to fill documentation gaps or re-interview hard-to-reach owners and use the AI chat over uploaded documents to answer targeted questions quickly.
Use the platform chat to ask questions such as 'Which centers lacked refrigerators and which OTBs were responsive? ' and retrieve center-level evidence.
Security & trust
Evidano uses encrypted storage and proprietary models tuned for qualitative research, and the platform does not use uploaded data to train third-party models.

FAQ: implementation fidelity of rabies vaccination
What is implementation fidelity and when should I measure it?
Implementation fidelity is the degree to which a program is delivered as intended, across content, coverage, frequency, and duration.
Measure implementation fidelity after a campaign to diagnose execution gaps or in real time to monitor rollout quality and inform corrective actions.
How do I compare centers or segments reliably?
Compare centers reliably by using a consistent checklist (binary or graded), triangulating with interview themes, and running cross-segment summaries.
Use the 27-item checklist as a common audit tool, and run co-occurrence analyses to identify patterns that are replicable across data sources.
Is AI-enabled qualitative research secure and ethical?
AI-enabled qualitative research can be secure and ethical when it uses consented, research-only workflows with PII redaction and encrypted storage.
Maintain IRB or ethical approvals and local consent procedures, and use platform features for redaction and access control to protect participants.
Wrapping up & next steps
The Cochabamba study shows that implementation failure, not vaccine efficacy, is the main barrier to rabies elimination in this setting and that structured fidelity assessment can prioritize repairs.
Program teams that pair a structured 27-item fidelity checklist with CFIR-guided qualitative diagnosis can prioritize repairs to cold chain, staffing, coordination, and communication.
