Each year over 1.5 million children die before their fifth birthday from vaccine-preventable diseases; most live in impoverished countries. Immunizations are one of the most cost-effective interventions proven to save lives and are considered a basic healthcare measure for all children. Unfortunately, many children and families around the world do not have the same access to life-saving vaccines that are available in the United States and other higher-income countries. Vaccine Ambassadors leverages the goodwill of individuals and organizations to become partners in this important global health initiative. Together we can make a lasting impact that is tangible, affordable, and profoundly meaningful.
