In The Politics of Autism, I analyze the myth that vaccines cause autism. This bogus idea can hurt people by allowing diseases to spread. Examples include measles, COVID, flu, and polio. A top antivaxxer is HHS Secretary RFK Jr. He is part of the "Disinformation Dozen." He helped cause a deadly 2019 measles outbreak in Samoa.
As of May 28, 2026, 1,983 confirmed* measles cases were reported in the United States in 2026. Among these, 1,974 measles cases were reported by 40 jurisdictions: Alaska, Arizona, California, Colorado, District of Columbia, Florida, Georgia, Idaho, Illinois, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Montana, Nebraska, New Jersey, New Mexico, New York City, New York State, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Texas, Utah, Vermont, Virginia, Washington, Wisconsin, and Wyoming. A total of 9 measles cases were reported among international visitors to the United States.
There have been 30 new outbreaks** reported in 2026, and 93% of confirmed cases (1,847 of 1,983) are outbreak-associated (517 from outbreaks starting in 2026 and 1,330 from outbreaks that started in 2025).

When asked by a senator on April 22 what he was doing to reduce the number of measles cases and improve the MMR vaccination rate, Kennedy responded, “Improve the MMR. We promote the MMR. We have advised every child to get the MMR. That’s what we do.”
In the same hearing, Democratic Sen. Michael Bennet of Colorado similarly asked, “Are you taking the position, as your CDC director has taken, that the measles vaccine is vital to keeping American children healthy in this country? Are you taking that position today? That has not been your position.”
“That’s my position. I — we promote the measles vaccine,” Kennedy said. “The measles vaccine prevents measles in 97% of the people who take it. I’ve always said that. That’s what the science says.”
Kennedy had often noted the MMR vaccine’s effectiveness. But prior to last month, we could not find a single instance in which Kennedy offered vigorous, unqualified support for the vaccine, without including or later adding inaccurate or misleading information that might cause someone to rethink vaccination.
