Episode notes
Vaccine Clots Are Not The Same As Pill Clots
- The clotting events tied to COVID vaccines differ biologically from pill-related clots, so direct risk comparisons are often misleading.
- Vaccine clots involved low platelet counts and unique mechanisms that require different treatments than typical contraceptive thromboembolisms.
Early Pill Trials Exploited Puerto Rico And Weak Consent
- Early contraceptive trials ignored modern informed consent and often used marginalized populations like Puerto Rico for testing.
- Researchers exploited legality, eugenic policies, and mass sterilization campaigns to run trials outside U.S. states where contraception was illegal.
Postmarket Data Revealed Rare Pill Harms
- Post-approval surveillance is crucial because trials involve far fewer people than real-world use, letting rare side effects emerge.
- The pill's early approval affected hundreds of thousands, revealing issues unseen in limited premarket studies.
