World Immunization Day 2025 by WHO: Protecting health, preventing disease, and promoting trust

Every year on November 10, the world observes World Immunization Day — a moment to recognize one of the greatest achievements in public health: vaccines. In 2025, as the world continues to recover from recent outbreaks and adapt to new health challenges, the message remains clear: immunization saves lives.

Why immunization still matters

Vaccination is one of the most cost-effective ways to prevent disease. It protects not just individuals but entire communities by reducing the spread of infectious diseases such as measles, polio, influenza, and COVID-19. According to the World Health Organization (WHO), immunization prevents between 3.5 to and 5 million deaths every year.

Yet, vaccine-preventable diseases continue to cause illness and death, especially in low- and middle-income countries. Gaps in coverage, misinformation, and vaccine hesitancy threaten progress. World Immunization Day 2025 calls for renewed action to close these gaps through awareness, education, and equitable access.

Building vaccine confidence through literacy

At Health Literacy Asia, we believe that improving health literacy — the ability to access, understand, and use reliable health information- is central to boosting vaccine confidence. People are more likely to get vaccinated when they understand how vaccines work, their safety, and the collective benefit of herd protection.

Misinformation remains a global challenge, amplified by social media and digital echo chambers. Initiatives that combine scientific communication with empathy, such as community dialogues, transparent data sharing, and AI-assisted education tools, are helping rebuild public trust.

Regional progress in Asia

Asia continues to make significant strides in expanding immunization coverage through innovation and digital transformation.

• India: Large-scale digital platforms such as U-WIN and e-VIN track vaccinations,
register children and pregnant women, and manage vaccine supply chains.

• Indonesia: Platforms like SMILE and ASIK strengthen vaccine supply-chain monitoring
and immunization coverage across the archipelago.

• Vietnam: Systems such as ImmReg and VaxTrak support a nationwide digital immunization
registry and help send vaccination reminders.

Meanwhile, regional collaborations led by ASEAN and the Asia-Pacific Immunization Partnership focus on strengthening vaccine supply chains and outbreak preparedness.

However, disparities persist — particularly in remote and marginalized communities, where limited healthcare infrastructure, transportation challenges, and cultural misconceptions continue to hinder access. Addressing these inequalities remains key to achieving universal immunization goals.

This year’s campaign theme — “Immunization for All is Humanly Possible” — highlights the global commitment to innovation, resilience, and community health.
On World Immunization Week 2025 (24 – 30 April) and through the broader observance on 10 November, individuals, healthcare workers, and policymakers are urged to:

• Get informed: Rely on credible health sources for vaccine information.
• Get vaccinated: Protect yourself, your family, and your community.
• Get involved: Support awareness campaigns and encourage others to stay up to date with their immunizations.

Vaccines are not just medical tools; they are symbols of solidarity — proof that when science, policy and community come together, lives are saved.
