Episodes 4 & 5 of "Measles" combine to explore modern measles outbreaks and vaccine hesitancy through the lens of the 2014 Disneyland outbreak. Julia Cartwright traces how one infectious visitor sparked 147 cases across seven states, demonstrating measles' explosive transmission in communities with low vaccination rates. The episode examines the complex factors behind vaccine hesitancy—from success-bred complacency and misinformation spread through social media to legitimate concerns about institutional trust and individual autonomy. Julia respectfully explores why some educated, affluent communities show higher hesitancy rates while revealing the real-world consequences: vulnerable populations at risk, strained healthcare systems, and economic costs reaching millions during outbreaks.

"Measles" chronicles the scientific breakthrough that changed history—the development of the measles vaccine. Julia Cartwright follows researchers like Dr. John Enders and Dr. Thomas Peebles as they painstakingly grew the measles virus in laboratory cultures, starting with a sample from an eleven-year-old boy named David Edmonston. The episode details the years-long process of weakening the virus through multiple cell cultures, conducting rigorous safety trials, and scaling up production for mass distribution. Julia explains how this scientific achievement transformed childhood from an era of inevitable disease and death to one where parents could finally protect their children from measles' devastating effects.

"Measles" transports listeners to the pre-vaccine era when measles was an inevitable part of childhood. Julia Cartwright paints a vivid picture of life before 1963, when three to four million American children contracted measles annually and families lived in constant fear during spring outbreak seasons. The episode explores how communities developed coping mechanisms, from "measles parties" to hospital overflow protocols, while parents helplessly watched children battle high fevers and complications. Through historical accounts and family stories, Julia reveals the profound psychological and economic toll measles took on society, demonstrating why vaccine development was so desperately needed to free families from generations of terror and loss.

Measles" introduces listeners to the reality behind what many consider just a childhood rash. Host Julia Cartwright explains how the measles virus spreads through respiratory droplets and why it's one of the most contagious diseases known—capable of infecting twelve to eighteen people from a single case. The episode traces measles' progression from initial exposure through the distinctive rash, revealing serious complications like brain inflammation, pneumonia, and immune system damage that can last years. With current global statistics showing hundreds of thousands of annual cases, Julia demonstrates why measles remains a serious public health threat requiring respect and vigilance.
