Medium's web design makes my eyes bleed.
“I compare the phenomenon of illicit drug use to influenza. During the course of a year influenza changes slightly, which is why you get a new jab every year. But every 10 to 15 years we see a major shift. The year-to-year swaying and back-and-forth of influenza is called antigenic drift: the world and the bug interacting. When avian or pig flu or something like that appears, that’s called an antigenic shift. When these big changes occur, our immune response is negligible. We can’t fight it. And then we need completely new vaccines.”
Still, excellent reporting.
