Vaccines, vaccines, vaccines (a la Matthew McConaughey).

It was a contentious first day at the CDC vaccine advisory committee meeting, but keep scrolling to read the next entry in our American Science, Shattered series, a heartbreaking story that explains why a “BLOBFISH” is critical to both cancer and autism research.

VACCINES

Vaccine panel poised to recommend ending hep B vaccinations at birth

The first day of the latest Advisory Committee on Immunization Practices meeting was a doozy: a 30-year-old recommendation that all babies born in the U.S. be vaccinated at birth against hepatitis B seems likely to end

Infectious diseases experts say the move could result in more than a thousand babies contracting the highly infectious virus each year, a chronic disease that can lead to premature death. The final vote was delayed until today, but yesterday’s discussion suggests that members are planning to overturn the existing policy with few dissenters (though it did get testy, thanks in part to pediatrician Cody Meissner). 

It’s setting up to be a big win for health secretary Robert F. Kennedy Jr. and the anti-vaccine movement that supports him, even though hepatitis B shots have been given for decades and the current body of evidence indicates they are safe. 

What else to expect for today? Presentations from two controversial figures: Tracy Beth Hoeg, the newly-named FDA drug center head, and Aaron Siri, Kennedy’s former personal attorney, who has represented people who have allegedly been harmed by vaccines. Senate health leader Bill Cassidy (R-La.) called the ACIP “totally discredited” on Thursday upon learning that Siri would be testifying.

POLITICS

Time running out on an ACA tax credit extension

The prospect of extending the enhanced Affordable Care Act premium tax credits remains dim.

The extra subsidies that Democrats began providing during the pandemic to lower premiums expire on Dec. 31. Senate Democrats are proposing a three-year extension, and Majority Leader John Thune (R-S.D.) promised to bring a vote on the subsidies’ extension to the floor. 

But significant obstacles remain. Senate Republicans are opposed to an extension of that length, but they also have yet to agree amongst themselves on their position. Minority Leader Chuck Schumer (D-N.Y.) seems to have thrown in the towel on finding common ground with the GOP. And no matter what happens next, it’s clear Democrats plan to make health care affordability a key issue in next year’s midterm elections.

Vinay Prasad, behind closed doors

Vinay Prasad, the Food and Drug Administration’s embattled vaccines regulator, blamed “misleading media narratives” for escalating criticism of his leadership, a day after 12 former FDA commissioners said his proposed changes to vaccine policy would have dire consequences for American public health.

Speaking yesterday at a New York investor conference closed to the public and press, Prasad defended his plan, which would require manufacturers to conduct longer and larger studies before updating vaccines, as a matter of modernizing FDA policy. He did not address his claim that the Covid-19 vaccine killed 10 children. 

Prasad’s brief tenure at the FDA has been marked by power struggles and a chaotic work environment. Read on for more of Prasad’s remarks in this closed-door meeting, courtesy of STAT’s Damien Garde and Lizzy Lawrence. 



SCIENCE, SHATTERED

A brilliant lab humming with discovery falls silent under Trump

Sophie Park for STAT

You should read Angus Chen’s profile of bioinformatician John Quackenbush, whose Harvard lab has developed a remarkable set of tools that help scientists understand how genes are controlled. Quackenbush’s lab has emptied after Trump started slashing funds that fueled research programs all over the country.

As of this year, Quackenbush’s work has a staggering 100,000 citations. His lab was once full of postdoctoral fellows, graduate students, and interns, working on cutting-edge computational biology research and creating big data tools, including one the National Cancer Institute named among the most important advances of 2024. His open-source and adorably-named “Network Zoo” tools helped researchers investigate everything from autism to cancer.

In the latest edition in our “American Science, Shattered” series, Angus captures the personal and intellectual heartbreak that happens after a lab loses funding. Read more. 


VACCINES, AGAIN

Single shot HPV vaccine may be enough to fight cervical cancer

Cervical cancer is deadly, killing about 340,000 women worldwide annually, but new findings from a huge study in Costa Rica show that a single shot of the HPV vaccine could be just as effective as two shots in protecting girls and young women in harder-to-reach low-income countries.

The study enrolled more than 20,000 girls between ages 12 and 16 and tested two different HPV vaccines used around the world. After five years, the researchers found that a single shot provided about 97% protection.

“We have the evidence and tools to eliminate cervical cancer. What remains is the collective will to implement them equitably, effectively, and now,” wrote an infectious disease specialist who wasn’t involved in the study. Read more.


VACCINES, AGAIN, AGAIN

Ethiopia eyes experimental Marburg vaccine after outbreak

Ethiopia, which is battling its first outbreak of Marburg disease, has agreed to conduct a Phase 2 trial of an experimental vaccine aimed at protecting against the virus. The Washington-based Sabin Vaccine Institute has sent nearly 650 doses of its experimental Marburg vaccine to the country, which has recorded 13 confirmed cases so far, eight of which have been fatal.

The open label trial will give a dose of vaccine to some people at high risk of contracting Marburg — health care and front-line workers and contacts of cases who've been in contact with a patient within the past 21 days, the incubation period for the virus. Other similar workers will be given a dose of the vaccine on a delay, so they can serve as a comparator group.

The vaccine, which is also in Phase 2 trials in Uganda and Kenya, was designed by scientists at the National Institutes of Health. — Helen Branswell
