Routine childhood vaccination has been one of the most effective public health interventions of the 20th century and one of the most cost-effective strategies of disease prevention and prevents approximately two to three million deaths annually worldwide.
Today, fewer children die from vaccine-preventable illnesses than older individuals. To address the burden of vaccine-preventable illness in an aging population, health care institutions will need to adopt innovative vaccination approaches.
A life-course immunization strategy, which includes vaccination throughout an individual's lifetime, allows individuals to age with less illness risk, allowing for healthy, active, and productive aging.


There is no denying the importance of vaccines, yet children continue to be denied access to this essential tool. Vaccines can save an additional 1.5 million lives. The Extended program of immunization (EPI's) accomplishments, along with the eradication of smallpox in 1980, laid the groundwork for launching aspirational vaccine-preventable disease goals over the next 20 years, including poliomyelitis eradication, maternal and neonatal tetanus elimination, and measles and rubella elimination in all WHO regions.
There are five impediments to vaccination, including: 1) Vaccine hesitancy: Confronting vaccine hesitancy is one of the core challenges in immunization, with vaccine safety concerns being the main contributor;2) Disparities; A growing number of children in urban areas are unable to access vaccines, indicating that distance is not the only barrier to vaccination. This is a result of political and social neglect, as infants in these urban areas may not be registered with the government.3) Resources; there must be enough vaccines available to provide everyone with the necessary vaccinations. While the supply market for the majority of vaccinations has favorable news, 4) Fragility: Vaccination also faces challenges from fragility. Vaccination becomes even more challenging in regions where population displacement is a result of war, natural disasters, or humanitarian crises.
Opportunities to fully use vaccines are within reach, but doing so calls for focused, determined effort by governments and partners in vaccination. To ensure that people of all ages and in all parts of the globe may reap the full health and well-being advantages of vaccinations, the Immunization Agenda 2030 lays out a plan of action for the next decade.
