Micromotors deliver oral vaccines

Vaccines have saved millions of lives, but nobody likes getting a shot. That's why scientists are trying to develop oral vaccines for infectious diseases. But to be effective, the vaccine must survive digestion and reach immune cells within the intestinal wall. Now, researchers have developed oral vaccines powered by micromotors that target the mucus layer of the intestine.
