Africa's polio-free certificate needed a signature the world would believe. Hers was it.
The rise
Raised in rural Cameroon, she won a place through the African Scholarship Program of American Universities — the only woman among the eighteen candidates who passed — studied in Indiana and Illinois and took her doctorate at the Université de Montréal in 1975. She built her career at the University of Yaoundé I on malaria in pregnancy, showing that parasites hide in the placenta even when a mother's blood test comes back clean.
What they did
As chair of the Africa Regional Certification Commission she spent years refusing to certify countries whose surveillance data she judged too thin — Nigeria among them. Only in August 2020 did the commission declare the WHO African Region free of indigenous wild poliovirus. She sat on WHO's Malaria Policy Advisory Committee and runs a mentoring programme for African women in science.
The full picture
No substantiated controversy attaches to her. The fair caveat concerns the milestone itself: vaccine-derived poliovirus continues to circulate in several African countries, so the 2020 certification covered wild poliovirus only and was narrower than most headlines suggested — a distinction she has made repeatedly herself.
Why it matters
Technical authority only counts when someone is prepared to exercise it against pressure to sign. She held a continental declaration hostage to the quality of the data behind it, and only then put her name to it.
