World Immunization Week 2026 – April 24 to 30th


World Immunization Week takes place in the last week of April. It reminds us how vaccines help protect people of all ages from serious diseases.

Vaccines are one of the best tools we have to keep people healthy. In the past 50 years, vaccines have saved more than 150 million lives. This happened because people chose to protect themselves, their children, and their communities. That equals about 6 lives saved every minute.

These choices matter. Health workers give vaccines. Parents bring their children to clinics. Communities work together. Because of this, diseases like measles, polio, and whooping cough are much less common.

Vaccines have helped more babies survive. In fact, infant survival has improved by about 40%. Millions of children have also been protected from lifelong disabilities. Today, more children grow up healthy and live longer lives. Which is why now more than ever with measles outbreaks increasing in the United States to stay up to date on your vaccination status. When more families choose the measles vaccine, it also helps protect babies and others who are too young or too sick to get vaccinated.

Vaccines protect us at every stage of life:
• Babies and young children: Their immune systems are still growing, so they get vaccines early to protect them from diseases like measles, polio, and hepatitis.

• Teens: Booster shots help keep protection strong. Some vaccines also protect against new risks, like HPV and meningitis.

• During pregnancy: Vaccines help protect both the parent and the baby. Protection can pass to the baby before birth.

• Adults and older adults: As we age, our bodies need extra help fighting illness. Vaccines can protect against flu, COVID-19, pneumonia, and shingles.

This year’s theme is: “For every generation, vaccines work.” Vaccines have protected families for many years—and they continue to protect us into the future.
