After making its first public entrance into the US this summer with a tool that pings people to donate blood during shortages, Facebook's health team is expanding the effort nationwide.
Inspired by those pleas, Budaraju and her team rolled out an official Facebook blood donations tool in the country in 2017.
The company later expanded the feature to Pakistan, Bangladesh, and Brazil, where more than 35 million Facebook users signed up, Budaraju said.
Eventually, the company hopes to move toward only allowing organizations to request blood in every country where the tool is operational, she said.
Budaraju said the tool has already helped to facilitate tens of thousands of donations, saving lives by making it easier for people in need of safe blood to find willing donors with matching blood types.
