Welcome to The Logoff: Today, Dylan Scott and I are focusing on US Health Secretary Robert F. Kennedy Jr.’s decision to fire every member of a federal vaccine advisory board, an attack on medical science that will have negative repercussions for public health.

What’s the latest? Kennedy fired every sitting member of the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices on Monday.

What does this board do? For more than 60 years, the panel has advised the federal government on vaccine policy, providing guidance — that officials have almost always followed — on which shots people should get and when.

What’s next? The vaccine advisory committee was first convened by the surgeon general in 1964, but it is not enshrined in federal law. That means Kennedy can change its membership or dissolve the panel entirely if he so desires. In firing the board’s members, Kennedy called it “little more than a rubber stamp for any vaccine.” 

What does this mean for us? Absent clear, science-based federal guidance on vaccines, it’ll be harder for us to know which shots health experts think we should be getting. And, more broadly, it’ll be harder for the population to achieve “herd immunity” — when enough people are vaccinated against a disease to prevent it from spreading widely.

What’s the big picture? Kennedy has a long history as a vaccine “skeptic,” promoting unfounded theories about the supposed health risks of vaccines responsible for saving millions of lives. As Health secretary, he has made vaccine policy — and undermining the value of those vaccines — a centerpiece of his agenda.

And with that, it’s time to log off…

Life is short, as is our time with the people around us. But it’s easy, in the daily grind, to forget that and to focus instead on petty annoyances. That’s a bad way to live, so I really appreciated this Vox piece on the dangers of resentment, both to ourselves and our relationships. It’s a great reminder of what matters. Thanks so much for reading, and I’ll see you back here tomorrow.

‘Political albatross’: CNN data guru dubs Kristi Noem serious political problem for Trump



Dramatic new polling results have revealed that Americans want Homeland Security Secretary Kristi Noem fired and a majority oppose ICE's actions, according to CNN's data guru Thursday.

CNN chief data analyst Harry Enten described the attitude among voters towards ICE's harsh immigration tactics and specifically the high dissatisfaction against the Trump administration, namely Noem, who has led and carried out Trump's harsh immigration policies — and now 58% of Americans want her out of the job.

"The numbers absolutely tell a story," Enten said. "It has been a bad political situation for the president of the United States. And more than that, it is only getting worse. Just take a look at ICE's approval rating. I mean, look at this. And unfortunately immigration. Look, it was already low in early January, right? It was -17 points. But look, after the events of the last month, we are now talking about -29 points, the worst it has ever been. You look among independents, it is even worse than that. We are talking about a negative 40, -40 net approval rating for ICE on enforcing immigration laws. No wonder the president of United States, the president of United States, is changing his tone. And that is because you just look here. You see, the American people aren't just not with him — they are on a totally other planet."

The results have also pointed to a serious problem for President Donald Trump.

"Yeah, there's a reason why John [Berman] stuttered over that and couldn't figure out exactly, because the bottom line is this Kristi Noem has turned into an absolute political albatross," Enten said.

"Look at this. Take a look here. Voters on Noem job performance disapproved in early January 50th 2% and now want her fired. Fired is up to 58%, 58% want her removed," Enten added. "We're not just talking about the fact that her disapproval rating is through the roof. We're now talking about nearly 3 in 5 Americans who believe that Kristi Noem should be removed from her job as DHS secretary. No wonder Tom Homan is in there. And that is because Kristi Noem is a big reason why this has turned into such a deepening political problem for the president."
