Research & Publications
Dr. Omer has conducted studies in the United States, Guatemala, Kenya, Uganda, Ethiopia, India, Pakistan, Bangladesh, South Africa, and Australia. Dr Omer’s research portfolio includes epidemiology of respiratory viruses such as influenza, RSV, and - more recently - COVID-19; clinical trials to estimate efficacy of maternal and/or infant influenza, pertussis, polio, measles and pneumococcal vaccines; and trials to evaluate drug regimens to reduce mother-to-child transmission of HIV. Moreover, he has conducted several studies on interventions to increase immunization coverage and acceptance. Dr Omer’s work has been cited in global and country-specific policy recommendations and has informed clinical practice and health legislation in several countries. He has directly mentored over 100 junior faculty, clinical and research post-doctoral fellows, and PhD and other graduate students.Dr. Omer has published widely in peer reviewed journals including the New England Journal of Medicine, JAMA, Lancet, British Medical Journal, Pediatrics, American Journal of Public Health, Science, and Nature and is the author of op-eds for publications such as the New York Times, Politico, and the Washington Post.
Dr Omer has received multiple awards –including the Maurice Hilleman Award by the National Foundation of Infectious Diseases for his work on the impact of maternal influenza immunization on respiratory illness in infants younger than 6 months-for whom there is no vaccine. He has served on several advisory panels including the U.S. National Vaccine Advisory Committee, Presidential Advisory Council on Combating Antibiotic-Resistant Bacteria -Vaccine Innovation Working Group, and WHO Expert Advisory Group for Healthcare Worker Vaccination. He has also served as an academic affiliate of the Office of Evaluation Sciences –formerly known as the White House Social and Behavioral Sciences Team.
