One New Strategy •Many bacteria have genes that can make products like toxins or even antibiotics against other bacteria. •Forcing bacteria to grow with another kind of bacteria might cause them to start secreting a new antibiotic to kill off the competition. •This new antibiotic could be used to kill resistant bacteria. Staphylococcus aureus, cultured on an agar plate for drug sensitivity test Simple Dissolvable Patch for Vaccines •Scientists have created a dissolvable patch that is currently being tested which will deliver vaccine into the skin painlessly. • Microscopic needles made from a special blend of vinyl and freezedried vaccine can be pressed against the skin causing the needles to dissolve in the body’s fluids. •This eliminates risk of shared needles and it can be easily administered by health care officials. Edible Vaccines in Food • Many studies are currently being done to modify plants to contain vaccines. • Plant-based edible vaccines would be safer, cheaper, and could be grown—or freeze-dried and shipped—anywhere. • Vaccines delivered in food trigger a two-way immune response. • Oral vaccines initiate a systemic and mucosal immunity, which fights infections in places where germs first attack the body: in the mucous membranes of the nose, mouth, lungs, gut, and genitals. Using Plants to Make Vaccines • Plants can be genetically modified to produce vaccines as they grow. • The process of growing the vaccine in a plant is about three times faster, and can cut costs by about 75 percent, compared to conventional methods.
