1 . More than 60 years and almost 1,200 donations later, Harrison, whose blood contains an antibody (抗体) that has saved the lives of 2.4 million babies from miscarriages (流产), retired as a blood donor on May 11. Harrison’s blood is valuable because he naturally produces Rh-negative blood, which contains Rh-positive antibodies. His blood has been used to create anti-D in Australia since 1967.

“Every bottle of anti-D ever made in Australia has James in it,” Robyn Barlow, the Rh program director told the Sydney Morning Herald. “It’s an amazing thing. He has saved millions of babies. I cry just thinking about it.” Since then, Harrison has donated between 500 and 800 milliliters of blood almost every week. “I’d keep going if they let me,” Harrison told the Herald. His doctors said it was time to stop the donations. They had already extended the age limit for blood donations for him, and they’re cutting him off now to protect his health.

7 . Growing up in a small village in Ghana, Osei Boateng watched many of his family members and neighbors struggle to access basic health care. In many regions of the country, it can take hours to get to the nearest hospital. “My grandmother was a very big part of my life,” said Boateng. “It was very hard when we lost her, and it was due to something that could have been easily prevented. That is the painful part of it.”

Feeling an urgent call to help, Boateng decided he would make it his life’s mission to bring health care to remote communities in Ghana. He started his nonprofit, OKB Hope Foundation, and in 2021, he converted a van into a mobile doctor’s office called the Hope Health Van and started bringing health care directly to those in need. A few times a week, the mobile clinic and medical team travel long distances to remote communities in Ghana and provide routine medical care for free. On each trip, Boateng’s team consists of a nurse, a physician’s assistant, a doctor, and an operation assistant. In the van, they can run basic labs like bloodwork and urinalysis as well as prescribe and provide medications.

Since its launch, Boateng says the Hope Health Van has served more than 4,000Ghanaians across more than 45 rural communities who otherwise don’t have easily accessible medical care.

Boateng has big plans for the future. He hopes to expand to provide more consistent and high-quality medical care not only to those living in remote areas of Ghana but in other countries as well. He has gone all in on his OKB Hope Foundation, recently quitting his job to dedicate his time to bringing health care to his home country. But for him, the sacrifices are well worth the reward.
