The Development of Which Vaccine Would Most Dramatically Reduce Death

Question

The development of which vaccine would most dramatically reduce death rates in sub-Saharan Africa?
A)Tuberculosis
B)HIV
C)Malaria
D)Cholera
E)Smallpox

Accepted Answer

Malaria is the leading cause of death in sub-Saharan Africa, accounting for approximately 405,000 deaths in 2018 alone. Developing an effective vaccine for malaria would have a significant impact on reducing death rates in the region. While vaccines for other diseases, such as tuberculosis and HIV, are also important, they do not have the same level of impact on mortality rates in sub-Saharan Africa as malaria. Cholera and smallpox have largely been eradicated, so a vaccine for those diseases would be less impactful in this region.
