Telling kids to drink their medicine may soon have a whole new meaning. Researchers at Northwestern University have invented a way to give vaccines through a yogurt culture. Immunizing against many infectious bacteria will someday soon be as easy as mixing a fruit smoothie.

The university said in a statement that the oral vaccine relies on probiotics, which are healthy bacteria found in dairy products. After being ingested, the genetically altered flora make their way into the patients' small intestine and then start to produce the vaccine in your gut.

Adults will likely be first to say goodbye to nasty needles as the initial oral vaccines will be for anthrax and possibly breast cancer. The findings are published in the journal "Proceedings of the National Academy of Science."
