Guest: Dr. Tyler Evans, infectious disease and public health expert; Also: Trump escalates his (and fossil fuel industry's) War on Climate Science...

The Trump Administration is at war against science (and reality) on at least two different fronts, both of which we dig into on today's BradCast. One is the Administration's War on the Science of Public Health, the other is the ongoing War on Climate Science. [Audio link to full show is posted below this summary.]

We begin with Administration's full-frontal attacks on public health, as Secretary of Health and Human Services (HHS), Robert F. Kennedy, Jr., testified before a U.S. Senate Committee today, facing tough questions from Democrats and even a few Republicans. Some of the colloquies turned into shouting matches.

Kennedy's years-long personal war against life-saving vaccines --- including the COVID vaccine --- often took center stage throughout the three-hour proceeding. But things had gone off the rails long before he showed up to take several verbal beatings today. Among some of the context for today's hearing: An anti-vax gunman shot up the CDC in early August; Kennedy's cancellation of half a billion dollars in research grants for new mRNA vaccines of the type that helped get us out of the COVID pandemic and could offer cures for cancer and other diseases; His firing of the CDC Director last week, less than a month into her tenure because, as she claims in an op-ed today, she refused to follow Kennedy's demand to "preapprove the recommendations of a vaccine advisory panel newly filled with people who have publicly expressed antivaccine rhetoric".

Add to that, the state of Florida's announcement this week by its loony Surgeon General, Dr. Joseph Ladapo, that it is lifting all vaccine mandates for school children, including for measles, mumps, rubella, chickenpox, tetanus and polio. Ladapo compares vaccine mandates for school children to slavery. As one elected official in Florida said in response: "This is a public health disaster in the making for the Sunshine State." Unfortunately, as our guest today seems to concur, the entire nation is now facing the possibility of a similar public health disaster under the second Trump term.

We're joined today for a thoughtful discussion on all of this and more by DR. TYLER EVANS, infectious disease and public health expert and former Chief Medical Officer for New York City amid its COVID-19 response. Evans is now CEO and co-founder of the Wellness and Equity Alliance and author of the new book, Pandemics, Poverty, and Politics: Decoding the social and political drivers of pandemics from Plague to COVID-19.

It's impossible to adequately summarize our wide-ranging conversation, but I will share a few brief quotes...

  • On RFK Jr.: "At this point, effectively every trusted and established or distinguished organization around infectious disease and public health are essentially demanding his resignation. Time is up. His answers are circular logic. They're definitely not based in science. And the more he talks --- particularly for folks who really understand the science --- it's like nails on a chalkboard for us."
  • On the effect of vaccine conspiracy theories on public health: "If somebody is in the emergency room and you hear two doctors actively arguing about somebody's diagnosis and treatment, how do think that's going to make the patient feel? ... What we're seeing right now with RFK is doing exactly that. His intent is clearly to disrupt as much of the science as well as the implementation of science in public health as much as he possibly can."
  • On the politicization of public health: "It doesn't matter if it's a blue or red city, state. At the end of the day, microbes, or other pathogens, or environmental stressors don't understand the difference between red and blue. It's all humans to them. We really need to depoliticize public health. ... We are politicizing everything about public health [and] now it's getting worse."
  • On RFK's defunding of mRNA research: "At this point, we have millions of data points demonstrating it is incredibly safe. The mRNA literally is the most effective vaccine against COVID-19. So these claims that somehow they're not effective, or unsafe, are just patently untrue. They're just completely made up. ... This guy is just completely making stuff up. The defunding of the science behind advancing further mRNA vaccines just hurts all Americans."

Evans has much more on all of the above today, as well as on lessons he learned during the worst of the COVID pandemic in NYC; his personal experiences responding to viral outbreaks, like Ebola, around the world; the importance of a competent federal government during an historic pandemic; the lunatic that Florida has installed as its top public health official and more. "If we are removing vaccination mandates, particularly for kids, it is probably one of the most disastrous things we could ever do, from a public health standpoint," says Evans about the cancellation of vaccine mandates in the Sunshine State.

We ran longer than expected with Evans (though it was well worth it), but we still had a few minutes left today for Desi Doyen to take on Donald Trump's latest escalation in his War against Climate Science and specifically on cheap, clean, renewable, abundant wind and solar energy. All of that before closing with our latest Green News Report on new California wildfires; the deadly landslide in war-torn Sudan; and dozens of climate scientists taking on the Trump Administration's absurd "report" by five prominent climate science deniers meant to serve as the basis for the Administration's cancellation of hundreds of billions of dollars in critical climate change initiatives...

Yes, it's a very busy BradCast today...
