These pills work like tiny speedboats.
A new type of tiny motor can help shuttle life-saving vaccines to where they need to go. For infants or those of us who are squeamish around needles, that could mean a future with fewer shots and more effective medicine.
The problem with oral vaccines — ones that take pill form — is that they can sometimes get broken down by stomach acid or get spit right back up by a child. That’s why researchers are interested in tiny, molecular motors that can propel the pills through the body to their target, making orally-consumed medication more effective than ever before.
