Pfizer CEO Albert Burla explains Pfizer's new technology to the Davos crowd.
“Swallowed tablets with a tiny chip send a wireless signal that the drug has been digested. Imagine the level of such control! It's very exciting!” Burla said.
A year ago, chipping was denied, and people with such theories were ridiculed. Now, the situation has been reversed.
