Summary

Mass immunization strategies are used to protect populations by rapid vaccination of large numbers of individuals. While routine immunization of infants has become the main vaccine delivery strategy in most developing countries, mass immunization continues to be an important tool to rapidly increase the immunity in response to an impending outbreak, or an outbreak that has just begun; in settings with low or absent routine immunization; and where populations have been displaced, and routine immunization services disrupted. Mass immunization is also used to rapidly decrease susceptibility when a new vaccine is being introduced into routine immunization programs. Finally, mass immunization is used to achieve decreases of the morbidity and mortality associated with a vaccine-preventable disease (e.g., measles), and to increase population immunity to the levels required to interrupt disease transmission in order to achieve global eradication. Routine and mass immunization remain important strategies to attain national and international vaccine-preventable disease control and eradication goals, but mass immunization should not be used as a substitute for strengthening weak routine immunization programs.
