Value of Immunization: Global Issues
Antibiotic resistance is the ability of certain strains of microorganisms to develop partial or complete resistance to antibiotics, rendering the antibiotic ineffective to treat the disease or condition. Antibiotic resistant infections carry high treatment costs and can threaten the security of others, increasing the importance of prevention for those vaccine-preventable diseases prone to the development of antibiotic resistance.

Conflict and Humanitarian emergencies
Humanitarian emergencies and infectious diseases have a mutually negative impact on one another. Crisis settings like refugee camps, war zones and communities hit by natural disasters are often plagued by factors that increase the risk and severity of infectious diseases. Malnutrition, poverty, crowding, complicating health issues and minimal or no access to medicine and other treatment services are common, and increase the importance of disease prevention efforts like immunization and clean water. At the same time, the unchecked spread of potentially vaccine-preventable diseases in these communities can further destabilize already fragile communities and dramatically increase suffering.
Health security refers to the importation of diseases across international borders that may present a threat to domestic disease control. Disease prevention worldwide through immunization is critical for increasing domestic health security. The increasing Antibiotic Resistance of some diseases, such as pneumococcal disease and tuberculosis, is especially worrisome given the high cost of treatment and capacity for these diseases to spread. The spread of disease across borders can have serious Economic consequences.
An outbreak of infectious disease is defined as the occurrence of a disease in a population at levels above the expected baseline. These unexpected clusters of disease are costly to investigate and control, and if unchecked, can grow to epidemic proportions. A large proportion of infectious disease outbreaks in the past two decades were due to vaccine-preventable infectious diseases, underscoring the importance of primary prevention -- through high immunization coverage. Infectious disease outbreaks have widespread consequences for the health system, economic growth, social and political stability beyond the immediate impact on the health of those affected. The economic toll can include everything from reductions in international trade and lost productivity, to the significant financial strain on families from costs of treatment and caretaker productivity losses.
