David Sack, M.D., is a Professor of Internal Health at the Bloomberg School of Public Health with a joint appointments in the Department of Epidemiology and Infectious Diseases, Johns Hopkins University. Dr. Sack’s research has been focused on enteric infections and vaccine development for these infections. With regard to enteric infections, this has included laboratory detection of these agents, describing their epidemiology in developing country populations and travelers developing appropriate clinical management strategies including antibiotics and rehydration methods.

With regard to vaccines, Dr. Sack has participated in the development of vaccines for cholera, rotavirus, enterotoxigenic E coli (ETEC), and shigellosis. Currently, he leads a large project called the DOVE project (Delivering Oral Cholera Vaccine Effectively). Working in collaboration with UNICEF, WHO and other partners, this project facilitates the use oral cholera vaccine as part of an integrated strategy for cholera control. A web site providing details on the use of oral cholera vaccine is at

To develop vaccines for ETEC, Dr. Sack collaborates with scientists at Kansas State University on a new approach, called MEFA (muti-epitope fusion antigens) to provide broad protection against these bacterial infections by targeting the many colonization factors and toxin antigens with a single fusion protein. The MEFA vaccine is now in the preclinical phase but soon will begin clinical trials.
