サマリー
あらすじ・解説
Alex Calder examines how smallpox functioned as an unintentional biological weapon that facilitated European colonization of the Americas by killing up to 95% of indigenous populations who lacked immunity. The episode traces how this catastrophic demographic collapse created power vacuums that allowed small groups of European colonizers to establish footholds against previously mighty civilizations while reshaping environments through ecological changes. Alex explores the development of variolation practices across cultures before examining Edward Jenner's cowpox experiments that led to vaccination—humanity's first intentional victory against a deadly disease. The story culminates with smallpox becoming the only human disease ever deliberately eradicated through global cooperation, showing how this virus both enabled imperial conquests through uneven immunity and ultimately inspired one of medicine's greatest achievements.
