摘要

Background

Human Papillomavirus (HPV) remains the leading cause of cervical cancer in Ecuador, which suffers from systemic programmatic failures that undermine the global elimination strategy.

Crisis

Ecuador’s HPV vaccination coverage (35.6% first dose; 17.3% complete) is the lowest in Latin America, starkly contrasting with the WHO’s 90% target for cervical cancer elimination (Pan American Health Organization 2025). Structural inequities, a profound genotypic mismatch with the circulating quadrivalent vaccine (HPV 58/31/52 prevalence), and fragmented implementation perpetuate this public health crisis (Jose Ortiz Segarra et al. Infectious Disease Reports, 15(3):267–278 2023).

Key Findings

Our analysis reveals that the nation’s health-center-based model fails to reach vulnerable populations, a problem exacerbated by critical cold chain deficiencies in 30% of facilities. In contrast, regional successes, such as Peru’s school-based programs (94% coverage) and Colombia’s strategic adoption of the nonavalent vaccine, offer a clear roadmap for reform (Pan American Health Organization 2025, María Ines Sarmiento-Medina et al. PLOS ONE, 19(2):e0297579 2024).

Recommendations

We propose an evidence-based 5-point plan to overhaul Ecuador’s strategy: a targeted nonavalent vaccine pilot, immediate adoption of a single-dose schedule, culturally adapted self-sampling programs, phased-in gender-neutral vaccination, and urgent investment in cold chain infrastructure.
