World Immunization Week

World Immunization Week, beginning on 20 April, aims to promote one of the world’s most powerful tools for health—the use of vaccines to protect, or immunize, people of all ages against disease.

Immunization is one of the most successful and cost-effective health interventions, preventing an estimated two to three million deaths every year. From infants to seniors\, immunization protects against diseases such as diphtheria, measles, pertussis (whooping cough), pneumonia, polio, rotavirus, rubella and tetanus. The benefits of immunization are increasingly being extended to adolescents and adults, providing protection against life-threatening diseases such as influenza, meningitis, and cancers (cervical and liver cancers).

However, even now, an estimated 22 million infants are not fully immunized with routine vaccines, and more than 1.5 million children under age five die from vaccine-preventable diseases.
