Which of the following is a government-run volunteer organization for medical and public health professionals?

The Medical Reserve Corps (MRC) is a government-run volunteer organization specifically designed to support medical and public health professionals in their efforts to enhance community health and preparedness. Established in 2002, the MRC integrates volunteers into local health services and disaster response efforts, allowing them to provide essential services during emergencies and public health initiatives. This organization emphasizes taking advantage of the skills of local healthcare professionals, enabling them to contribute to their communities effectively.

In contrast, the Peace Corps, while also a volunteer organization, focuses on international development and does not specifically cater to medical and public health professionals. The Immunization Action Coalition is a nonprofit organization that promotes immunization, but it does not operate as a government-run volunteer organization. The National Guard serves a different purpose, primarily related to military readiness and national defense rather than establishing a volunteer network for public health professionals. Thus, the MRC is the option that best fits the description of a government-run volunteer organization for medical and public health professionals.
