La Rioja has expanded its vaccination program with LOLA after increasing adult vaccination coverage by 30%. The initiative shows how clinical Voice AI can strengthen prevention strategies while improving efficiency and public health outcomes.
La Rioja’s public health department has relaunched its AI-powered proactive outreach program after LOLA, Tucuvi’s clinical Voice AI agent, helped increase vaccination coverage by 30% during the 2025 campaign.
The new phase of the program will once again contact older adults by phone to provide information about shingles and pneumococcal vaccination, answer questions in real time, and help patients schedule appointments at their primary care centers.
The continuation of the program demonstrates how artificial intelligence can strengthen preventive care initiatives when it is safely integrated into clinical practice and public health strategies.
Why has La Rioja relaunched LOLA?
The decision follows the strong results achieved during the first phase of the program.
Between August and September 2025, LOLA placed 6,347 phone calls to people born in 1959 and 1960, providing information about recommended vaccines and supporting them throughout the decision-making process.
The results were significant:
- A 30% increase in vaccination coverage among people born in 1960.
- An 85.2% response rate.
- 44% of contacted patients accepted the shingles vaccine.
- 40% accepted the pneumococcal vaccine.
- Hundreds of people who had previously declined or postponed vaccination chose to get vaccinated.
Based on these outcomes, La Rioja’s public health department decided to expand the initiative by launching a new vaccination campaign.
How does clinical AI improve vaccination campaigns?
Adult vaccination campaigns present major challenges for healthcare systems, including reaching thousands of people, addressing individual concerns, and improving access to vaccination without increasing clinicians' workload.
Clinical Voice AI helps automate much of this process through natural, personalized conversations with patients.
With LOLA, the system can:
- Proactively contact eligible patients.
- Provide information based on evidence-based clinical protocols.
- Answer frequently asked questions.
- Identify potential issues that require follow-up.
- Help patients schedule vaccination appointments.
By automating these routine interactions, clinical teams can dedicate more time to patients who require direct clinical attention.
National recognition for a public health best practice
The project's results have also been recognized by the Spanish Vaccinology Association, which awarded the initiative an Honorable Mention in the Public Health Best Practices category.
The award recognizes both the improvement in vaccination coverage and the innovative approach developed by La Rioja’s public health department.
Using AI to strengthen prevention and population health
The relaunch of LOLA reflects a growing trend across healthcare systems: using artificial intelligence to strengthen prevention strategies and improve communication with citizens.
Beyond automating phone calls, clinical AI can increase participation in preventive care programs, enhance the patient experience, and optimize the use of healthcare resources.
With this new phase of the program, La Rioja’s public health department continues to invest in an evidence-based model that combines innovation, clinical expertise, and AI to improve population health outcomes.
