2. Professor Faith Osier: Bringing Vaccine Manufacturing Home to Africa
Professor Faith Osier is leading a revolution that speaks directly to African women’s empowerment: ensuring the continent can produce its own life-saving vaccines.
From Clinical Reality to Research Mission
Born in Kenya in 1972, Professor Osier’s path to immunology began with clinical experiences treating children with malaria. She now serves as Professor of Malaria Immunology at the University of Oxford while maintaining active research groups in Kenya and the UK.
Chanjo Hub: Africa’s Vaccine Independence
The COVID-19 pandemic exposed Africa’s dangerous dependence on imported vaccines. In response, Professor Osier founded Chanjo Hub, an Africa-led vaccine manufacturing initiative that embodies true empowerment through self-sufficiency.
Currently piloting an mRNA malaria vaccine, she aims to transfer complete vaccine manufacturing technology to Africa. The Kenya BioVax Institute and Kenya Medical Research Institute are collaborating to ensure African scientists can produce vaccines from scratch, on African soil.
This is empowerment in action: giving Africans control over their health destinies rather than depending on external solutions.
Innovation Rooted in African Research
Professor Osier pioneered KILchip, a custom protein microarray that enabled her team to analyze antibody responses to over 100 malaria proteins in blood samples from 15 African locations. Her methodology demonstrates that cutting-edge scientific innovation can and should happen on the continent.
Named a 2018 TED Fellow and recipient of the Royal Society Africa Prize, Professor Osier was recognized by the BBC as one of seven trailblazing women in science in 2017. She serves as Vice President of the International Union of Immunological Societies, ensuring African voices shape global scientific policy.

3. Professor Francisca Nneka Okeke: Breaking Barriers in Nigerian Physics
Professor Francisca Nneka Okeke’s career is a testament to what becomes possible when women refuse to accept limits on their potential.
First Female Professor in Science at University of Nigeria
Born in Onitsha, Nigeria, Professor Okeke became the first female indigenous Professor in Science and Engineering at the University of Nigeria, Nsukka. She was also the first female Professor in Eastern Nigeria, the first female Head of Department of Physics and Astronomy, and the first female Dean of the Faculty of Physical Sciences.
Every “first” she achieved opened doors for the women who followed.
Climate Research With Global Impact
Professor Okeke’s research on the equatorial electrojet and ion currents in the upper atmosphere has significant implications for understanding climate change, natural disasters, and space weather. Her work connects local Nigerian research to global climate challenges.
Throughout her career, she published over 100 papers in international journals, 20 minor articles, and 15 books. She supervised 36 Masters students and 23 PhD students, multiplying her impact through mentorship.
Recognition That Inspires
In 2013, Professor Okeke received the L’Oréal-UNESCO For Women in Science Award for Africa and Arab States. That same year, New African magazine listed her among the Top 100 most influential Africans. The International Astronomical Union honored her with asteroid 149831 Okeke, a permanent celestial tribute to her contributions.
Championing Women in Physics
Professor Okeke married renowned physicist Professor Pius Nwankwo Okeke at 18 and raised six children, all pursuing science. Her life proves that women can excel in physics while building families, challenging the false choice society often presents to women scientists.
