Which figure served as surgeon general of the Continental Army and advocated vaccination?

• A. Haym Salomon
• B. Jonathan Trumbull Sr
• C. Benjamin Rush
• D. James Otis

Answer: (C)

Focusing on someone who bridged military medical leadership with public health action shows why this figure fits best. Benjamin Rush was a prominent physician who served in a senior medical role for the Continental Army, and he strongly advocated for smallpox inoculation as a protective measure for soldiers and civilians. His push for vaccination came at a time when disease devastated armies, so his combined duties in the military medical corps and his public health stance made him the clear fit. The other individuals are notable in political or civilian life, but they are not known for medical leadership or vaccination advocacy, so they don’t match the combination described here.
