WORLD IMMUNIZATION WEEK 2027

WORLD IMMUNIZATION WEEK 2027 (24TH – 30TH)

World Immunization Week, celebrated in the last week of April, aims to highlight the collective action needed and to promote the use of vaccines to protect people of all ages against disease.

Through its convening power, WHO works with countries across the globe to raise awareness of the value of vaccines and immunization and ensures that governments obtain the necessary guidance and technical support to implement high quality immunization programmes. The ultimate goal of World Immunization Week is for more people – and their communities – to be protected from vaccine-preventable diseases.

Vaccines save up to 5 million lives every year. Yet millions of children globally still miss out on essential life-saving protection.

Over the past 50+ years, immunization efforts have saved more than 150 million lives worldwide. From eradicating smallpox to driving polio cases down by 99.9%, vaccines remain humanity’s most powerful public health tool.

“A world protected by vaccines is a world where every child gets the chance to thrive.”

As World Immunization Week 2027 begins (April 24–30), we highlight the essential role routine immunizations play in preventing over 20 life-threatening diseases. Vaccines protect individuals, insulate healthcare systems, and safeguard our future generations.

Let’s champion equal vaccine access for every child, everywhere. Check with your local health provider to ensure your family is fully protected today!
