A nonprofit group founded by prominent anti-vaccine advocate Robert F. Kennedy Jr. is suing Rutgers University over its COVID-19 vaccine mandate.

Childrens Health Defense filed the lawsuit Monday on behalf of 18 Rutgers students. The plaintiffs argue that the universitys policy, which requires all students to be fully vaccinated for the fall semester, is illegal and an affront to human dignity and personal freedom because it violates our basic right to control our bodies.

It appears unlikely that the legal challenge will prove successful. Last week, the U.S. Supreme Court declined to take up a similar challenge that eight students brought against Indiana Universitys vaccine mandate.

There is arguably no one who has done more to spread COVID-19 vaccine misinformation and hesitancy than Kennedy Jr., the son of former presidential candidate Robert F. Kennedy and an environmental lawyer. He has peddled a number of debunked conspiracies about all sorts of vaccines, including that they cause autism.

In February, Instagram permanently banned him for spreading misinformation about the safety of COVID-19 vaccines.

Despite its campaign to convince Americans not to get a potentially life-saving shot, Childrens Health Defense touts itself as being devoted to the health of people and our planet. The organizations website is filled with coronavirus misinformation and conspiracy theories, and goes so far as to compare vaccine mandates to racial segregation .

Childrens Health Defense and one other group accounted for more than half of all anti-vaccine advertising on Facebook, according to a paper published in January 2020. Media Bias/Fact Check, a fact-checking website, labels the organization a strong conspiracy and quackery level advocacy group.
