This experience inspired her to leave clinical medicine and become a public health practitioner. She returned to the US for a Master’s in Public Health from Johns Hopkins University. After completing this, she joined the US Centers for Disease Control and Prevention (CDC) as an Epidemic Intelligence Service Officer. After spending two years in Seattle working for the state health department, Dr. Cairns moved to Atlanta to complete a preventive medicine residency in CDC’s domestic TB program. In 2000, she began to work in the field of global immunizations with a focus on measles control. From 2000 – 2014, she held a variety of positions within CDC’s Global Immunization Division, including four years on detail to the World Health Organization’s (WHO’s) China office where she served as leader of the WHO immunization team. In 2014, she retired from CDC. Since then she has worked as an independent consultant to a variety of agencies, including Gavi, the Vaccine Alliance, WHO’s South East Asia Regional Office, the University of British Columbia, and CDC.
