African inoculation against smallpox predated and was suppressed by racist European science

Evidence

Fifteen years prior, Mather had asked Onesimus one of the standard questions that Boston slaveholders asked new house slaves—Have you had smallpox? “Yes and no,” Onesimus answered. He explained how in Africa before his enslavement, a tiny amount of pus from a smallpox victim had been scraped into his skin with a thorn, following a practice hundreds of years old that resulted in building up healthy recipients’ immunities to the disease. This form of inoculation—a precursor to modern vaccination—was an innovative practice that prevented untold numbers of deaths in West Africa and on disease-ridden slave ships to ports throughout the Atlantic. Racist European scientists at first refused to recognize that African physicians could have made such advances. Indeed, it would take several decades and many more deaths before British physician Edward Jenner, the so-called father of immunology, validated inoculation. — Ibram X.

Categorization

• XREF: Directly contradicts the reader’s stated test case concern: here an idea (racist refusal to credit African medicine) predates and obstructs a life-saving practice — but the racist idea itself is produced to serve self-interest and status defense, so it fits Kendi’s inversion read differently. Worth studying as the strongest apparent counterexample in the chapter.
• SEED: Angle: how the ‘father of immunology’ myth launders an African-origin practice — a case study in how canon-making erases origins, parallel to how European science absorbed Arabic mathematics.
• CANDY: The thing that most people call Jenner’s discovery was actually an old West African practice brought to Boston by an enslaved man named Onesimus.
