Vaccines have long been one of the most powerful tools in public health. Over the past 50 years, vaccines have saved more than 150 million lives – not by accident, but because ordinary people made the decision to protect themselves, their children and their communities from diseases like measles, diphtheria, pertussis, polio, and rotavirus.
Today, newer vaccines against malaria, HPV, cholera, dengue, meningitis, RSV, Ebola, and mpox are saving even more lives, and helping people at every stage of life live longer and healthier thanks to scientific advancements.
During World Immunization Week, let’s show the world that some family traditions are worth passing on. Under the theme, “For every generation, vaccines work”, World Immunization Week will promote how vaccines have safely protected people, families, and communities for generations – and continue to safeguard our future.
By building trust, sharing accurate information, and strengthening confidence, we can support families to make informed decisions that protect themselves, their children, and generations to come.
