The Smallpox Vaccine: A Historical Reminder of Ingenuity
The smallpox vaccine, developed using the live Vaccinia virus, left behind more than just immunity—it created a lasting circular scar on many arms. While the vaccination process was uncomfortable and unique, its ultimate purpose was revolutionary.
