About the Coalition against Typhoid

The Coalition against Typhoid (CaT), based at the Sabin Vaccine Institute (Sabin), works to prevent typhoid and other invasive salmonelloses through research, education, and advocacy. With more than 800 members, the Coalition acts as a catalyst in the global health community to coordinate partnerships, convene decision-makers, and advocate for sustainable solutions, including access to next-generation vaccines and clean water. The Coalition, formed in 2010, is guided by a multi-stakeholder steering committee. It is supported by the Bill & Melinda Gates Foundation.

Alongside CaT, Sabin leads research projects generating estimates of the burden of enteric fever around the world and conducts typhoid vaccine immunogenicity, effectiveness, and impact studies. Sabin’s Surveillance for Enteric Fever in Asia Project (SEAP) tracks enteric fever in Bangladesh and Nepal to establish disease burden and the potential impact of vaccines. Additionally, Sabin leads the Sero-epidemiology and Environmental Surveillance (SEES) project, which has developed and validated sero-surveillance tools to rapidly estimate the burden of enteric fever in community settings. The Sabin Vaccine Institute is a leading advocate for expanding vaccine access and uptake globally, advancing vaccine research and development, and amplifying vaccine knowledge and innovation. Unlocking the potential of vaccines through partnership, Sabin has built a robust ecosystem of funders, innovators, implementers, practitioners, policymakers, and public stakeholders to advance its vision of a future free from preventable diseases. As a non-profit with three decades of experience, Sabin is committed to finding solutions that last and extending the full benefits of vaccines to all people, regardless of who they are or where they live. At Sabin, we believe in the power of vaccines to change the world. For more information, visit www.sabin.org and follow us on X, @SabinVaccine.

Denise Garrett, MD, MSc

Dr. Denise Garrett, Vice President of Applied Epidemiology Programs, joined Sabin in August 2015 to lead the organization’s efforts in typhoid research and applied epidemiology. She serves as Director of the CaT Secretariat, leads Sabin’s SEAP project, supervises the SEES study, and manages numerous vaccine effectiveness and optimization studies in both Pakistan and Brazil. Dr. Garrett received her medical training in Brazil with a special focus on infectious diseases, including enteric fever.

Prior to joining Sabin, Dr. Garrett worked at the Centers for Disease Control and Prevention (CDC) for 23 years where she focused on international health and epidemiological research. During her time at the CDC, Dr. Garrett led several multi-center infectious disease studies in both low- to lower-middle-income and high-income countries. Dr. Garrett brings extensive experience in collaborating with international governments, multilateral agencies, universities, and private-sector, nongovernmental, and global health organizations to expand infectious disease control and prevention and outbreak response programs worldwide.
