Endless Thread

Even considering the winding road of scientific advancement and the new expressway that is the internet, what the heck happened in Clark County? With reporting from the ground in Washington and Oregon, we take the fourth episode of our vaccine series to trace the societal pathogens, identify the symptoms, and try to prescribe a solution to what some are calling a “canary in the coal mine” for a near future of eroding herd immunity and increasing threats of outbreak for all kinds of diseases in the U.S.

You can’t tell the story of today’s anti-vaccine — or “vaccine hesitant”— movement without telling a story of technology and social media. Part 3 of our "Infectious" series looks at the spread of anti-vaccine messaging online and how the Internet and social media have made it possible for vaccine-related misinformation and hoaxes to reach further and faster than ever before.

There was a time when the measles were common enough to be a source of comedy on TV shows like "The Flintstones." So how did we go from joking about the measles to reports on the news about a growing international measles emergency? In the second episode of our "Infectious" series, we embark on a search for truth, aided by a renowned pediatrician and several prominent anti-vaccine activists. Along the way, we look at how vaccines actually work, fallout from the swine flu pandemic, and the highly controversial -- but unproven -- link between vaccines and autism.

The problem with being healthy is that you completely forget what it feels like to be sick. In 2019, many people assume that the history of vaccination is recent history -- maybe a few centuries of innovation starting in the late 1700s. The truth is much more convoluted: centuries of ancient customs developing slowly into a cycle of extremes -- scientific innovation followed by fear, rejection, and sometimes, violence. In the first episode of our special series, 'Infectious,' we explore this recurring cycle and how it echoes still in 2019.
