Dr. Hattie Elizabeth Alexander’s work is important, because less people were being killed and her studies could later be built on to find cures to other viruses created related to influenzal meningitis. She first became interested in influenzal meningitis while interning at John Hopkins Hospital and anti-influenzal serum taken from horses had failed, she took in consideration the success of using a rabbit serum to treat pneumonia. Using rabbit serums helped her develop the effective cure for influenzal meningitis. In recognition, she received many awards including the E. Mead Johnson Award from the American Academy of Pediatrics, the Elizabeth Blackwell Award from New York Infirmary and the first women to receive the Oscar B.

Throughout her career she remained active in public health, serving on the influenza commission under the secretary of war during World War II, and as consultant to the New York City Department of
