Bill Nye the Science Guy explains why he blocked HHS Secretary RFK Jr.
Bill Nye has been a household name for decades, though many Millennials likely can't say his name without adding "the science guy" behind it. He played an integral part in the childhood of an entire generation with his television program teaching kids science in a fun, engaging way. The theme song will forever be emblazoned in the minds of those who grew up watching him.
When he made his way to social media with his familiar kindness and humor, people flocked to his pages for the nostalgia but stayed for the knowledge. If there was one thing Nye was going to do, it was stand with scientific evidence no matter what. Due to his love of science and being established as a trusted and pivotal voice in the worlds of science and tech, it wasn't surprising that the Secretary of Health and Human Services, Robert F. Kennedy, Jr. would have Nye's phone number. But what is surprising is that Nye blocked him.

A lot of scientific research is funded through the Department of Health and Human Services (HHS). Americans also depend on the accuracy of information leaving the office of HHS, whether it be vaccine recommendations, baby formula safety, or protective measures to be taken with a new disease outbreak. The department of Health and Human Services handles nearly everything that has to do with the health of American citizens and everyone who visits the country.
In 2025, Robert F. Kennedy Jr., an environmental lawyer and descendant of the Kennedy political dynasty, was confirmed as the new Secretary of HHS. While his nomination raised concerns due to his anti-vaccine activism and involvement in the Trump administration's Make America Healthy Again (MAHA) movement, the son of RFK assured Americans he would follow the science. But it would seem that this isn't the case according to the science guy who blocked RFK Jr. from being able to contact him via phone or text.

In a recent interview with Men's Health, Nye explains that the current health secretary would text him on occasion—but at some point the texts got to be out of hand. The magazine describes Nye holding up his iPhone to show multiple walls of text messages from RFK saying, "This is real. That’s Bobby Kennedy Jr.” Turns out Kennedy had been sending him long text messages back to back making an argument for not vaccinating children due to its (repeatedly scientifically debunked) claimed links to autism.
"Just no self-awareness. And if you read these articles he sent, they’re all this speculation about autism and just cause-and-effect, and mercury in vaccines, that maybe there’s a connection. I wrote him back and said, ‘Okay, I’ll read your book. I think you’ve confused causation with correlation. Your friend, Bill.’ And he sent this,” Nye told Men's Health before showing the interviewer more extremely long text messages. “So I wrote, ‘Okay, no more texts.’ And he started again! So I cut him off. He does not have good judgment. He is not suited for this job.”
Nye didn't stop with venting his frustrations around the excessive paragraphs of texts. The mechanical engineer, actor, and author frustratingly pointed out the recent measles outbreak in Texas, which has been attributed to a lack of vaccines that led to insufficient heard immunity.
"There’s an outbreak of measles in Texas. Did you hear about this? It was a religious sect that has historically low vaccination rates, "he says in part before later adding, "Unvaccinated people can, and usually do, spread a disease. And that’s why we have these rules, for public health! It’s not arbitrary."

The topic of vaccines, which RFK Jr. not only hit on, but droned on about incessantly via text message, seems to be a sticking point for Nye. He is clearly fired up while speaking to Men's Health about the issue, and it may be due to his own experiences as a child.
"The other thing that’s so remarkable about what’s going on now—I went to elementary school with a guy who had polio. You do not want polio! And the reason you don’t get polio is because of a vaccine that was discovered that keeps you from getting polio! What is wrong with you, man?" Nye said.
He explains the minute risk of contracting the disease from the vaccine, but stresses how rare it is before explaining how things worked before vaccines existed when he was a child. But this isn't the first time The Science Guy has shared his views on vaccines. He's done multiple interviews with outlets like Now This where he explains how vaccines work and was even part of a 2021 campaign to help kids understand how COVID vaccines protected them.
Nye doesn't just have a bone to pick with people who are against vaccinations, he is against anti-science and uses his platforms to educate the public. He's testified before congress and debunked conspiracy theories on Big Think. Nye has also ventured back into the entertainment industry with Bill Nye Saves the World, which ran from 2017-2018 and The End is Nye which aired on Peacock in 2022. Nye is a trusted voice for millions of Americans and, while blocking RFK Jr. might appear harsh to some, to others he's simply staying true to science.
