Panama’s HPV Vaccine Success: A Blueprint for Global Cervical Cancer Elimination
Every two minutes, a woman dies from cervical cancer. But a remarkable story is unfolding in Panama, offering a beacon of hope and a roadmap for countries striving to eliminate this preventable disease. A recent study, presented at the International Congress of the Papillomavirus Society (IPVS) in Bangkok in October 2025, highlights Panama’s impressive HPV vaccination rates and provides crucial insights into the challenges and opportunities ahead in the global fight against cervical cancer.
The Panama Paradigm: High Vaccination, Emerging Challenges
Panama stands out as a pioneer, having implemented the HPV vaccine as part of its national immunization program 17 years ago – a world first. The country currently boasts HPV vaccination coverage exceeding 85% among eligible girls, a figure significantly higher than many nations. This success is largely attributed to strong governmental support, particularly from the Ministry of Health (MINSA) and the Expanded Immunization Program (EPI), led by Itzel de Hewitt. However, the study, led by Dr. Arlene Calvo of the University of South Florida (USF), reveals a complex picture. While HPV vaccine adoption is high, coverage of Pap tests remains low – around 10% – and, surprisingly, cervical cancer mortality rates are increasing, even as incidence rates decline.
“We have to develop other specific studies to determine the impact of the vaccine; that will be the next step,” explains Dr. Calvo. “For now, we insist on the need to continue vaccinating boys and girls and for women to have Pap smears (PAP) or cytology done regularly.”
The Generational Shift & The Lag in Mortality Decline
This apparent paradox – declining incidence but rising mortality – is largely explained by a generational effect. The cohorts vaccinated against HPV are still relatively young and haven’t yet reached the age at which cervical cancer is most commonly diagnosed. Therefore, the full impact of the vaccination program on mortality won’t be fully realized for several decades. This underscores the importance of long-term monitoring and continued investment in screening programs.
Beyond Vaccination: The 90-70-90 Targets & Innovative Screening
Panama is actively working towards the ambitious 90-70-90 goals set by the World Health Organization (WHO) and the Pan American Health Organization (PAHO) for cervical cancer elimination. These targets aim to:
- Vaccinate 90% of girls against HPV before age 15.
- Screen 70% of women aged 35 and 45 with a high-precision test.
- Treat 90% of women with precancerous lesions and invasive cancer.
Achieving these goals requires a multi-pronged approach. Dr. Calvo and her team emphasize the need to reinforce vaccination in areas with lower coverage, expand screening options, and improve access to treatment, particularly for women in early stages of the disease. Innovative screening methods, such as self-sampling HPV tests, are proving particularly valuable in reaching underserved populations with limited access to healthcare facilities.
The Rise of Self-Testing and the Future of Cervical Cancer Screening
The limitations of traditional Pap smears – requiring trained healthcare professionals and laboratory infrastructure – are driving the adoption of self-testing technologies. These tests, which detect the presence of high-risk HPV strains, are becoming increasingly accurate and affordable. They empower women to take control of their health and overcome barriers to screening. However, ensuring timely follow-up and access to treatment for those who test positive remains a critical challenge.
Furthermore, advancements in HPV testing are allowing for more precise risk stratification, identifying women who require immediate colposcopy and treatment versus those who can be monitored with less invasive follow-up. This targeted approach promises to optimize resource allocation and improve patient outcomes.
Expert Insight:
“The use of updated data is necessary to understand the country’s public health profile and make appropriate decisions. We need to move beyond simply vaccinating and screening to a more nuanced approach that considers individual risk factors and ensures equitable access to care.”
Global Implications & The Role of Data-Driven Public Health
Panama’s experience offers valuable lessons for other countries aiming to eliminate cervical cancer. The study underscores the importance of sustained political commitment, robust vaccination programs, and innovative screening strategies. However, it also highlights the need for continuous monitoring, data analysis, and adaptation to evolving epidemiological trends.
The increasing incidence of cervical cancer among younger women, despite high vaccination rates, suggests that factors beyond HPV infection may be at play, such as lifestyle factors or co-infections. Further research is needed to understand these complex interactions and develop targeted prevention strategies.

Frequently Asked Questions
What is HPV and why is it linked to cervical cancer?
HPV (Human Papillomavirus) is a common virus that can cause various cancers, including cervical cancer. Certain high-risk HPV strains, particularly types 16 and 18, are responsible for approximately 70% of cervical cancer cases.
How effective is the HPV vaccine?
The HPV vaccine is highly effective in preventing infection with the HPV strains that cause most cervical cancers. Studies show efficacy rates of up to 97% against cervical cancer and 99% against genital warts.
What is the role of screening in preventing cervical cancer?
Regular screening, such as Pap tests or HPV tests, can detect precancerous changes in the cervix, allowing for early treatment and preventing the development of invasive cancer.
What can I do to protect myself from cervical cancer?
Get vaccinated against HPV, participate in regular screening programs, and practice safe sex. If you experience any unusual symptoms, such as abnormal vaginal bleeding, consult a healthcare professional immediately.
The fight against cervical cancer is far from over, but the progress made in Panama – and the lessons learned – offer a powerful testament to the potential for global elimination. Investing in vaccination, screening, and research is not just a public health imperative; it’s an investment in the future health and well-being of women worldwide.
