World Immunization Day

Observed each year on November 10, World Immunization Day is dedicated to raising awareness about the vital role of vaccines and immunisation in protecting people of all ages from vaccine-preventable diseases.

History of World Immunization Day

Immunisation has been recognised globally as a key public-health intervention for decades. According to global health organisations, vaccinations have helped save millions of lives by preventing illnesses such as measles, polio, diphtheria and tetanus.
While much of the coordinated global vaccination awareness is encapsulated in World Immunization Week (observed during the last week of April) under the banner of creating “Immunization for All”, the specific day November 10 is often cited by many sources as “World Immunization Day”.

Why is World Immunization Day important?

Immunisation is one of the most effective tools in public health—by providing protection not only to individuals but also to communities (through herd immunity), it reduces illness, disability and death from diseases that once spread widely and lethally.
Recognising this day helps sustain and renew efforts to ensure equitable access to vaccines for everyone—especially in regions where many still lack full immunisation coverage—even as new vaccine technologies emerge for diseases like malaria, RSV, and others.

• It highlights that immunisation helps protect the young, the elderly and the vulnerable.
• It reminds people that basic vaccines have saved millions of lives.
• It draws attention to gaps where some populations remain un- or under-vaccinated.
• It emphasises the ongoing need to invest in vaccine development, delivery systems and education.
• It promotes a global mindset: immunisation is everyone’s concern, crossing borders and demographics.

How to Observe World Immunization Day

Because this is a serious public-health observance aimed at awareness and action, it’s appropriate to observe the day—with learning, advocacy, outreach and support rather than a festive celebration.
Here are some meaningful ideas:

• Share a post on social media about your vaccination story or why vaccines matter—with the hashtag #WorldImmunizationDay.
• Encourage someone you know to get up-to-date with their vaccinations (or check vaccination status for children).
• Volunteer or support a local health clinic, community immunisation drive or education event on vaccines.
• Learn about the vaccines available in your country and ask your healthcare provider questions—especially for diseases you might not have thought about.
• If you are part of a school, community group or workplace, help organise a short talk or information sheet about immunisation and why it still matters.
