Soldiers are immunized against which mosquito-transmitted disease?

The correct answer is based on the specific immunization protocol provided to soldiers to protect them from certain diseases in areas where mosquitoes are prevalent. Yellow fever is a viral disease that is transmitted by infected mosquitoes, and there is an effective vaccine available to protect against it. The vaccine for yellow fever is a live attenuated vaccine that provides immunity for many years, which is particularly important for military personnel who may be deployed to endemic areas.

In contrast, while there are preventive measures for malaria, such as prophylactic medications and utilization of mosquito nets, there is no licensed vaccine for malaria available for use in soldiers. Dengue fever and Zika virus, although significant health concerns where mosquitoes are present, also do not have standardized vaccines that are typically administered to military personnel like the yellow fever vaccine. Thus, the focus on yellow fever as the correct answer reflects its status as a potentially severe and vaccine-preventable disease relevant to soldier health in specific locations.
