Why CDC is Involved in Global Immunization

Key points

As one of the most cost-effective ways to improve health, immunization is a best buy for public health. By extension, immunization strengthens national, regional, and global health security.

Vaccines prevent an estimated 4 million deaths a year.1

Vaccines protect children and their families from deadly and disabling diseases.

Despite the existence of safe and effective vaccines, vaccine-preventable diseases (VPDs) remain a leading childhood killer and global health threat. Why? Because about 1 in 5 children in the world do not have access to these lifesaving immunizations.

Vaccines improve lifelong health

While most vaccines go to young children through essential immunization services, vaccines against diseases such as human papillomavirus virus (HPV) and meningitis provide important protection to adolescents. Adult populations – such as high-risk groups like health workers and members of displaced communities – also benefit from immunizations. For outbreak-prone diseases like typhoid, cholera, Ebola, and yellow fever, vaccines protect community members of all ages.

Other ways immunization saves lives

By preventing the spread of VPDs, immunization programs save lives and prevent disease and disabilities. They also help:

  • Prevent outbreaks, reducing loss of life, health, safety, and livelihood
  • Strengthen global health security (as immunizations help decrease antibiotic resistance and economic instability)
  • Sustainably prevent, detect, and respond to VPDs, as well as other emerging disease threats

Immunization saves money

Each dollar spent on vaccination saves $52.2

In low- and middle-income countries, the return on investment from immunization programs is an estimated $52 per $1 invested. These savings represent the social and economic costs avoided because of vaccination.

Immunization is among the most cost-effective ways to support a healthier and safer world.

VPDs create costs for families, communities, businesses, and health systems. Immunizing and preventing disease reduces the risk of financial hardships and economic instability by avoiding:

  • Lost work and school days
  • Cost of medical care
  • Diversion of resources to outbreak response
  • Outbreak-related disruptions to local and global economies, travel, and trade

Immunization makes the world healthier and safer

People move around, and so do diseases.‎

In addition to protecting people from disease, vaccination also helps keep those diseases from spreading when people interact with others and their environment.

Immunization makes our world healthier and safer by:

  • Improving children's life expectancy and promoting a healthy start in life
  • Providing protection from preventable diseases throughout the lifespan
  • Protecting populations who are at risk due to occupation, displacement, or migration
  • Supporting a healthy and productive workforce in local and global economies
  • Advancing the safety and security for Americans where they live, work, and play

Immunization is a foundation for primary care

Vaccines connect people to health providers.‎

In many countries, immunization services play a vital role as an entry point into primary healthcare.

Visiting healthcare providers for vaccinations provides an opportunity to address overall health.

Healthcare workers can provide other health services that individuals or their family members may need beyond vaccines. This prevents or reduces individual and community health risks.

Measles is a leading cause of vaccine-preventable deaths worldwide. It causes widespread outbreaks in under-vaccinated communities. Through global vaccination coverage and immunization strategies, we're getting closer to eliminating measles worldwide.
