The development of vaccines has been considered one of the greatest public health success stories in history and "the most effective medical intervention” to reduce morbidity and mortality associated with infectious diseases (Rappuoli, Miller, & Falkow, 2002). The 20th century witnessed significant progress in the elimination of vaccine-preventable diseases as a result of international cooperation (e.g. GAVI) and worldwide campaigns (e.g. smallpox eradication) that aimed to reduce morbidity and mortality associated with vaccine-preventable diseases. 

However, the past decade has seen complacency and has lost momentum in regards to immunization programs. Over 2 million deaths occur every year as a result of vaccine-preventable diseases, largely in developing nations. These deaths and disease-related injuries to countless more each year represent a continuing injustice. The development of safe and effective vaccines and their distribution can save lives, as has shown to effectively do so. The international community and national governments around the world must recommit to immunization programs and pursue a vision of a society that respects the lives of all its citizens.
