True or False: Immunization schedules are updated only when new vaccines are recommended.

Immunization schedules are regularly updated based on a variety of factors, not solely when new vaccines are introduced. These updates can include changes in recommendations for existing vaccines, alterations in dosing schedules, and additional guidance on vaccine safety and effectiveness based on ongoing research and epidemiological data.

Health organizations, such as the Centers for Disease Control and Prevention (CDC) in the United States, actively monitor vaccine performance and outbreaks of vaccine-preventable diseases. As new data comes in, schedules can be adjusted to better address public health needs. Therefore, it is important for healthcare providers to stay informed about these updates to ensure optimal vaccination practices.
