As measles cases in the U.S. reach their highest level in a quarter century and RFK Jr. leads an anti-vaccine push from the federal government, it's crucial to understand the importance of vaccines.

Historian and University of Oklahoma professor Kyle Harper tells Ali Velshi that "vaccines are arguably the innovation, the discovery that has done more than any other to contribute to human health, to longevity, and to overall human wellbeing," and that "for most of the human past, infectious diseases were difficult or impossible to control." - Aired on 09/21/2025.

1. It is very much a case of protecting all of us.

I've been vaxxed and boosted all along. And with Asperger's social distancing is my superpower. I'm retired and able to control my exposure to the general public in a way that very few people are able. And I still got covid and it almost killed me. Now I have had long covid for two years and I can barely walk for twenty minutes at the most. All because the people in this area refused to take covid seriously. Covid is still killing 50,000 people a year in this country regardless of whether they believe it or not.
