World Immunization Week is a global initiative in public health aimed at promoting awareness and increasing immunization rates against preventable diseases worldwide. This campaign occurs annually during the last week of April (24th - 30th).

Immunization offers protection against 25 different infectious agents or diseases, spanning from infancy to old age, including diphtheria, measles, pertussis, polio, tetanus, and COVID-19. According to the World Health Organization (WHO), active immunization presently prevents 2 to 3 million deaths each year. Despite these achievements, approximately 22.6 million infants globally still lack basic vaccines, primarily in developing nations. Insufficient immunization coverage often arises from limited resources, competing health priorities, ineffective health system management, and inadequate surveillance. The primary objective of World Immunization Week is to enhance public awareness regarding the life-saving benefits of immunization and encourage individuals worldwide to obtain necessary vaccinations against life-threatening diseases for themselves and their children.
