Everyone has a role
World Immunization Week 2025 not only raises awareness about the importance of vaccines, it highlights how everyone can take action.
Individuals can ensure they and their families are vaccinated on time and share facts to help dispel misinformation.
Health workers can use check-ups as an opportunity to remind caregivers about the importance of keeping children up to date with vaccinations. Communities can show their support by engaging in World Immunization Week and promoting the benefits of vaccines.
Governments play a critical role. By prioritizing investments in immunization at local and national levels, they can strengthen primary health care system and ensure that every child, regardless of where they are, has access to lifesaving vaccines. Governments are urged to invest in resilient immunization systems, especially in low-coverage areas and among zero-dose children, to ensure protection for all.
Key messages
Vaccines are one of the humanity’s greatest achievements. Over the last 50 years, essential vaccines have saved 154 million lives, including 25 ,illion lives in the Eastern Mediterranean Region. Vaccines account for 40% of the improvement in infant survival over the last half century, enabling more children than ever before to celebrate their first birthday.
Despite these significant gains, progress has stalled. In 2023, 14.5 million children worldwide didn’t receive any routine vaccine dose, including nearly 3 million children in the Eastern Mediterranean Region.
Call for action
WIW emphasizes the urgency of the situation, calling on governments to prioritize immunization investments and promote regional solidarity to close gaps. Vaccinating all children through routine and supplementary immunization efforts is crucial protect from deadly diseases like measles and to stop wild poliovirus, which remains endemic in Afghanistan and Pakistan, and to preventing further outbreaks of variant poliovirus.
As the campaign makes clear: “We are at a critical moment in global health. To protect one of humanity’s greatest achievements, we must be relentless in reaching every child and person with vaccines – from infants to elders, from rural communities to conflict zones. Immunization for all is humanly possible, and it is within our reach if we work together.”
