Regarding vaccines, Dr. Sack has participated in the development and testing of vaccines for cholera, rotavirus, enterotoxigenic E coli (ETEC), and shigellosis. His projects are working to understand the epidemiology of cholera in Africa and Asia, Working in collaboration with UNICEF, WHO and other partners, these cholera projects improve our understanding of transmission and facilitate 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 www.stopcholera.org.

To develop vaccines for ETEC, Dr. Sack collaborates with scientists at University of Illinois 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.

?The Doctors? TV show recently turned to Dr. David Sack for expert comment on dabbing, a highly dangerous way of ingesting marijuana that is growing in popularity, especially among teens. Dabs, also known as butane hash oil (BHO), honey oil, budder, shatter, crumble and wax, are made by extracting THC (tetrahydrocannabinol), the primary psychoactive ingredient found in cannabis. ?In the old days, marijuana had a concentration of about 5% and now when you?re looking at hash oil, you?re talking about a concentration of 80%,? Dr. Sack explained, pointing out that a single dab ?could be as potent as five joints.? It gets to the brain ?right away,? Dr. Sack said. The result is a high that can lead to extreme paranoia, blackouts, rapid heartbeat and psychosis ? but that?s only part of the danger. Because creating a dab involves heating marijuana plants using butane, manufacturing it is incredibly dangerous. Last year in California alone, 30 people were killed as the result of massive burns and other injuries sustained while cooking up this high. Watch the video here.
