GENEVA/NEW YORK – April 24, 2026 – In a concerted effort to combat declining vaccination rates and reinforce the life-saving power of immunization, major global health organizations have launched a comprehensive campaign titled "For every generation, vaccines work." Observed during World Immunization Week (April 24-30, 2026), this initiative by the World Health Organization (WHO), UNICEF, and Gavi, the Vaccine Alliance, aims to underscore the lifelong protection vaccines provide and urge renewed commitment to global immunization efforts.

The campaign theme highlights how vaccines have safely protected individuals, families, and communities for generations and will continue to safeguard future lives. It acknowledges that over the past 50 years, vaccines have saved more than 150 million lives globally, with an estimated six lives saved every minute. This year's push comes at a critical juncture, with Gavi's 2026-2030 strategic period (Gavi 6.0) placing a strong emphasis on reaching "zero-dose" children and improving equity in immunization, particularly in regions affected by conflict, instability, or fragile health systems.

Recent years have seen concerning trends in immunization coverage. The "Big Catch-Up" initiative, a multi-year effort launched in 2023 to address declines exacerbated by the COVID-19 pandemic, successfully delivered over 100 million vaccine doses to approximately 18.3 million children across 36 countries. However, despite this success, agencies warn that millions of infants still miss out on vital vaccines through routine immunization programs annually. In 2024, nearly 20 million children worldwide missed at least one vaccine dose, with 2.1 million of those in the Western Pacific Region alone, leaving them vulnerable to preventable diseases like measles and polio.

The "For every generation, vaccines work" campaign seeks to address these challenges by:

* **Raising Awareness:** Demonstrating how immunization has safely and effectively protected generations from deadly diseases.
* **Empowering Health Workers:** Equipping them with tools to communicate clearly and compassionately about vaccines, addressing hesitancy and questions from families.
* **Strengthening Public Understanding:** Fostering greater understanding of vaccine safety and effectiveness to enable informed decisions.
* **Closing Immunity Gaps:** Encouraging sustained and expanded vaccination coverage across all age groups.

New vaccines are also expanding the portfolio of protection, with Gavi supporting vaccines against diseases such as malaria, HPV, cholera, Ebola, and mpox, potentially saving millions more lives. Gavi's Gavi 6.0 strategy aims to immunize 500 million more children by 2030, with a target of saving an estimated eight million lives, including vaccinating 1.5 million girls against HPV. The Alliance is also focused on strengthening health systems, improving programmatic and financial sustainability, and ensuring healthy markets for vaccines.

As part of the ongoing efforts, UNICEF has also initiated targeted catch-up campaigns in regions facing severe outbreaks, such as the measles-rubella campaign in Sudan's Darfur States to protect six million children, and routine immunization catch-up campaigns in the Gaza Strip.

The campaign serves as a critical reminder that while significant progress has been made in preventing diseases and saving lives through vaccination, these gains must be protected and expanded. Global health leaders are calling for continued investment, strengthened trust in science, and collective action to ensure that immunization remains a cornerstone of global public health for every generation.
