Director of Infectious Disease ProgramsJHSPH Faculty Page
Dr. Laura Hammitt is Director of Infectious Disease Programs at the Center for American Indian Health and an Associate Professor at the Johns Hopkins Bloomberg School of Public Health. Her research focus is the epidemiology and prevention of pediatric infectious diseases, with a particular interest in Streptococcus pneumoniae, Haemophilus influenzae, and the ecology of the human microbiome as it relates to treatment and prevention of disease.
Dr. Hammitt earned her medical degree at the University of Utah in 1999 and completed a residency in pediatrics at Primary Children’s Medical Center in Salt Lake City, Utah, followed by an appointment as chief resident for one year. Dr. Hammitt subsequently joined the CDC’s Epidemic Intelligence Service (EIS), serving at the Arctic Investigations Program in Anchorage, Alaska. Here she worked on infectious diseases of particular significance in the American Indian and Alaska Native population. She travelled frequently to villages in rural Alaska in her capacity as PI of studies on invasive Haemophilus influenzae disease and the immunogenicity of repeat revaccination of adults with pneumococcal polysaccharide vaccine. She also led studies on the long-term immunogenicity of hepatitis A vaccine and hepatitis B vaccine, as well as the impact of pneumococcal conjugate vaccine on nasopharyngeal carriage.
Following EIS, Dr. Hammitt completed a fellowship in Pediatric Infectious Diseases at the Children’s Hospital in Denver, Colorado. In addition to clinical work, Dr. Hammitt conducted research on the immune response to live-attenuated influenza vaccine.
In 2008, after finishing her fellowship training, Dr. Hammitt moved to Kilifi, Kenya as a clinical epidemiologist and consultant physician at the local district hospital. While in Kenya, she led studies on the etiology of pneumonia in hospitalized children, catch-up immunization of children with 10-valent PCV, the impact of 10-valent PCV on invasive disease and nasopharyngeal carriage, and the population immunity to Hib disease.
Dr. Hammitt returned to the United States in 2011 to join the faculty at the Center for American Indian Health.
