The Brief

The Trump administration is studying the safety of an ingredient commonly used in vaccines, an additive that contains aluminum. Coming after other recent changes to vaccine policy, many public health experts worry that the administration may now try to remove the ingredient.

"We want no aluminum in the vaccine," President Donald Trump said recently at a White House briefing.

For almost a century, some important vaccines, including shots that protect against diphtheria, tetanus, hepatitis and the flu, have included aluminum salts, compounds that contain small amounts of aluminum. They are used as adjuvants to give the immune system an extra kick necessary to make the shots protective.

"Aluminum is added to some vaccines because it's a very safe, but also effective, stimulant of the immune system," says Dr. Jesse Goodman, a vaccine expert at Georgetown University who used to regulate vaccines at the Food and Drug Administration. "It basically stimulates your cells to make more antibodies and a stronger immune response overall."

But Health and Human Services Secretary Robert F. Kennedy Jr., a longtime vaccine critic, has questioned the safety of aluminum in vaccines for years. And a special working group is now studying the "safety of ingredients that are present in multiple different vaccines," including aluminum, for the Centers for Disease Control and Prevention's influential Advisory Committee on Immunization Practices.

One question the working group is considering is, "Do either of the two different aluminum adjuvants increase the risk of asthma?" according to a document outlining the group's mandate.

Most public health experts say there's no good evidence that aluminum is unsafe and ample evidence that it poses no real concern. In fact, a large Danish study recently debunked any danger.

"We do not see any evidence that aluminum is a cause of serious illness in childhood," says Anders Hviid, a professor of epidemiology at the Statens Serum Institut in Denmark who led the study involving more than 1.2 million Danish children. "There is no scientific reason to take aluminum out of childhood vaccines. There's no science that supports that it's dangerous."

But some researchers welcome the move.

"I really believe that aluminum in vaccines is inherently bad. Full stop," says Christopher Exley, a longtime critic of aluminum in vaccines who recently retired from Keele University in the U.K. "And so any suggestion that we're going to remove it, I think, is absolutely marvelous, not only for making America healthy again but for making the world healthy again."

In addition to concerns over asthma, Exley thinks aluminum can also increase the risk for other  health problems, including autism and attention deficit hyperactivity disorder.

Hviid and others say trying to remove aluminum would cause significant problems for protecting people against serious diseases. Most importantly, the vaccines that contain aluminum would be rendered ineffective.

"To simply remove aluminum — in effect destroying or limiting the effectiveness of vaccines — is incredibly stupid," says Dr. Stanley Plotkin, a leading authority on vaccine science at the University of Pennsylvania.

People are exposed to far more aluminum in the environment than from vaccines, Plotkin notes.

And if federal regulators deem aluminum unsafe as a vaccine ingredient, vaccine makers would have to develop and test alternatives, a process that could take years. Such a move could undermine public trust in existing vaccines.

"And what has happened with measles will happen with other diseases — that is, coming back to this country," Plotkin says. "So, do we want that? Well, apparently some people do."

Federal health officials have not stated that they would pull existing vaccines with aluminum salts from the market, or that they want any diseases to return.

HHS press secretary Emily G. Hilliard declined to respond to specific questions about the safety of aluminum adjuvants or the practicality of removing them, but said in an emailed statement that "ACIP is reviewing the body of science related to aluminum and other possible contaminants in childhood vaccine."

And some scientists are open to at least studying the question of removing aluminum salts.

"It's human nature to try to make things even better, right?" says Dr. Ofer Levy, a pediatrician who runs the Precision Vaccines Program at Boston Children's Hospital. "So with all of the sophisticated science we have in the year 2025, probably there's room for improvement."

But Levy stresses that any changes should only be made if unbiased, well-conducted studies support that. In the meantime, Levy and others say that no one should hesitate about getting a vaccine containing aluminum.

"The question becomes: How do we give voice to legitimate concerns about vaccines without throwing the baby out with the bathwater?" Levy says.

Reggae star Ziggy Marley has spent decades carrying one of music’s most celebrated legacies. But until now, he had never written a song directly about his father, Bob Marley.

That’s changed with “Many Mourn for Bob,” a track on Marley’s ninth solo album Brightside, his first release recorded in his new studio in North Hollywood.

Marley was just 12 when his father died of cancer in 1981. Now 57, Marley says the song instinctually emerged after years of life experience and producing the biopic One Love, which revisited his father’s struggles like an assassination attempt amid political violence in Jamaica.

“He went through some things that was really tough on a human being – and just understanding him in that light is to have a little bit more emotional, deeper connection to his experience,” Marley said in an interview at his studio.

Searching for the bright side

The deeply personal track is part of a splashy return for Marley, who's touring behind Brightside and will perform at the Hollywood Bowl on June 21.

The new album blends political themes, optimism and musical experimentation.

Its lead single, “Racism Is a Killa,” featuring Big Boi, pairs the heavy topic with an upbeat groove that he hopes will make the song more accessible to young people.

“We just wanna come out straightforward, like I never want to come out tiptoeing,” Marley said. “I want to say something that can catch your ears or catch your thoughts.”

That tension between darkness and hope runs throughout Brightside. Marley described the album as a reflection on enduring difficult periods – from the pandemic to the Los Angeles wildfires – without losing sight of optimism.

“Sometimes we get lost in that so much that we don't realize that there is always a bright side,” Marley said.

The 432 Hz experiment

The album also experiments sonically: Marley recorded Brightside using 432 hertz tuning instead of the standard 440 hertz in most mainstream music. Advocates of 432 hertz believe it produces a warmer, more meditative sound better synced to the natural world. (You can hear the difference for yourself here.)

“It's a lower musical frequency, but it's a higher frequency in a next sense of your spirituality and emotion,” he said. “So even though the numbers go down, the frequency actually go up.”

Marley sees the move as part of a larger search for new creative approaches.

“I'm very open-minded and always trying to evolve and just experiment with life and music,” Marley said.

The Grammy winner, who joins James Blake and Ed O’Brien of Radiohead as the most high-profile artists to record at the lower frequency, floated the idea of a larger movement among artists.

“Let's just have a revolution in the music industry,” he said. “Let's change the frequency.”

Building a dream

Marley works out of his Rebel Lion Studio in North Hollywood, its name a nod to his 2018 album Rebellion Rises while also a play on the word “rebellion.”

He described the studio as an extension of the independent spirit his father built with Tuff Gong Studio in Jamaica.

“My father had a dream, and I had a dream too,” Marley said.

Like with Tuff Gong, Marley also plans to expand the studio operation to include vinyl pressing as records continue their resurgence in the streaming era.

“There’s always gonna be a vinyl present going on,” Marley said. “A thousand years from now, people that we're still gonna need vinyl records to listen to music.”

For years, Marley said, he worked out of smaller home setups and rented facilities before deciding to build a larger permanent space in L.A.

Marley said the city has become central to his own creative evolution over the last two decades of living and working here.

Drawn initially by music, friends and the city's small but tight-knit Jamaican community, he says being surrounded by creatives from different backgrounds helped push his artistry in new directions.

“I left my safety and my community, my tribe, and come out by myself to L.A.,” he said. “But it's a great experience. It really helped my growth as a human being being here.”

What’s next

Fresh off the release of Brightside, Marley says he’s already working on another album – a notably quicker turnaround since his last album, the family-music release More Family Time in 2020,

“We're doing back to back,” he said.

He’s also busy writing a children’s book based on his feel-good hit anthem “True to Myself” and eyeing opportunities in front – or behind the camera – inspired by his time working on One Love and making the video for “Racism Is A Killa.”

“Same philosophy, same message, but within visuals, you know?” Marley said excitedly. “I want to create some stories and try out. I feel it coming. I can feel it.”

A new free record shop for survivors of last year’s Eaton and Palisades fires is celebrating with a grand opening party Saturday night.

After losing his home in the Eaton Fire, Brandon Jay founded Altadena Musicians to get instruments back into the hands of musicians who lost their gear in fires.

Now he’s doing that with vinyl records, too.

“We want to be here to help replace those items and support music in people’s lives that can’t necessarily afford it right now because they’re saving all their pennies just to live and also just to rebuild their homes,” Jay told LAist.

Jay says they’ve seen roughly 3,000 records donated so far. Now they have a dedicated space on Lincoln Avenue where fire survivors can sign up for time slots and shop for up to 10 records a month.

“It’s a really lovely distraction but it kind of keeps me going as well just to know that we’re trying to build something great for the community and keep us all moving forward,” Jay said.

The store will carry copies of the benefit album, Gimme Shelter: Songs for LA Fire Relief. The compilation features cover art by Shepard Fairey and L.A. specific tracks from artists like Elliott Smith ("Angeles" of course), Norah Jones, The Flaming Lips, as well as a cover of "Burning Down the House" by Talking Heads performed by Jay and about 50 other fire-impacted musicians.

A City Council committee voted Friday to shelve a proposed ballot measure aimed at cutting L.A.'s “mansion tax” nearly in half.

The ad hoc committee on Measure ULA voted 2-1 to set aside a proposal by Councilmembers John Lee and Marqueece Harris-Dawson that would have asked voters in November to reduce the ULA transfer tax rate for multifamily and mixed-use properties to somewhere between 2% and 3.5%, down from the current rate of up to 5.5%.

However, the ballot measure proposal was also referred to the City Council’s rules, elections, and intergovernmental relations committee, which could still choose to move it forward.

Instead, the ad hoc committee advanced a narrower pilot program that would reduce the property transfer tax only for newly built affordable housing projects.

The pilot program won't need voter approval in the form of a ballot measure. Committee Chair Ysabel Jurado, who introduced the substitute language, said she believes the city should avoid a ULA ballot measure because it’s still too early to evaluate the measure’s long-term effects.

“ I'm against going to the ballot, but I'm for making fixes that make this better,” Jurado said.

Voters will see a separate proposal on their ballots by the Howard Jarvis Taxpayers Association to effectively repeal Measure ULA.

If the L.A. City Council does not approve reforming the measure, the only decision on the ballot in November may be whether to keep the mansion tax in its current form or end it.

About the mansion tax

L.A. voters approved Measure ULA in 2022 to fund affordable housing and homelessness prevention. The measure taxes real estate sales over about $5 million. Since taking effect in April 2023, ULA has raised just over $1.1 billion from 1,633 real estate transactions, according to the city’s housing department.

The city projects it will generate about $500 million in the coming fiscal year — about half of what proponents initially promised. It has funded about 800 new affordable units and helped stabilize thousands of renters facing eviction, according to the housing department.

But critics say the tax has suppressed housing development. Several studies link the tax to a slowdown in apartment construction in Los Angeles, but ULA supporters say high interest rates and broader economic conditions are to blame.

The City Council's ad hoc committee on Measure ULA was formed earlier this year to study how the measure is working and develop potential reforms. That work took on more urgency inside L.A. city hall after the Howard Jarvis Taxpayers Association qualified a statewide ballot measure for November that would effectively repeal Measure ULA entirely.

Joe Donlin, director of the United to House LA coalition, which campaigned for the original measure, said the City Council committee made the right call by rejecting broader exemptions.

“By not taking up the extreme calls for broad, 15-year waivers that could cost the program about a third of its revenue, the committee acknowledged that ULA is working,” Donlin said in a statement.

A separate group of housing developers, union workers and advocacy groups calling itself the “Mend It, Don’t End It” coalition has been urging city hall to make changes to ULA. On Friday, the group said it supports the measure, but believes targeted reforms are still needed.

“Independent research shows that Measure ULA has slowed housing production in Los Angeles at a time when we need more housing, not less,” said Melanie Mendoza, a coalition spokesperson.

What the data show

The debate over ULA's impact played out in the committee room Friday morning. The city's chief legislative analyst reviewed seven independent studies on ULA’s impact. Three of those studies concluded ULA had suppressed housing production and reduced property tax revenues, while four found no meaningful negative impact.

Before ULA took effect, Los Angeles collected about $22 million a month in transfer tax. After that, it dropped to about $13 million. But city legislative analyst Henry Flatt told the committee a similar decline happened in cities without the tax, including Glendale, Long Beach, Pasadena and Santa Clarita.

“We are not currently convinced that Measure ULA has had an extremely negative impact on general fund revenues,” Flatt told the committee.

The county assessor's office read the same period differently. Scott Thornberry, an assistant assessor with L.A. County, told the committee that commercial and industrial property sales are falling in the city but not elsewhere in the county.

“We are seeing, we believe, a trend line of impact to property tax revenue growth in the city of L.A. specifically," Thornberry said.

What the committee did

Instead of the ballot measure, the committee voted to develop a five-year pilot program cutting the ULA tax to 1.5% for newly constructed affordable housing projects that meet specific requirements.

Lee, whose ballot measure was replaced with language advancing the pilot program, said he hadn't seen the substitute prior to Friday’s meeting and voted against it.

“This was just placed in front of me,” he said. Lee objected to a provision in the substitute recommendations calling for $30 million in new spending on homelessness support.

“Without knowing where this money's coming from, I'm going to have to vote no,” he said.

Lee told LAist he supports stronger oversight and technical improvements to Measure ULA, but believes a ballot measure is the right approach.

“Voters deserve the opportunity to consider targeted changes that would preserve the intent of the measure while addressing its unintended impacts on housing production and real estate activity in Los Angeles,” the councilmember said, in a statement.

Friday's meeting was the committee's final scheduled hearing. The committee, which is set to dissolve June 1, also voted to advance a narrower nonprofit tax refund limited to organizations that can prove all sale proceeds went directly to affordable housing.

The committee continued a separate motion on fire exemptions for Palisades fire victims, which will be heard by another council committee. A motion to loosen eligibility rules for the ULA Citizens Oversight Committee was noted and filed.

Councilmember Imelda Padilla, who introduced several of the committee's motions, said the process had been guided by a commitment to protect the measure.

"My goal has always been to listen carefully, bring people into the conversation, and protect ULA while honoring the voters' intent," she said at Friday’s meeting.

In her closing remarks, Jurado reflected on the three-member committee’s past work.

“We released $14 million in rental assistance to the most vulnerable Angelenos and $300 million for affordable housing,” she said. “We did in six or seven meetings what others couldn't do in five years.”

The ad hoc committee's recommendations now move to the full City Council.

Harris-Dawson and Lee’s ballot measure motion will be considered by the City Council’s rules committee at a later date, officials said.

Monsterpalooza, the annual movie-monster bash for horror fans, returns to the Pasadena Convention Center this weekend, starting Friday night (May 29) and lasting through Sunday.

What to expect

Now in its 18th year, devotees can rub elbows with legendary beastie creators, browse hundreds of vendors who traffic in the weird and unsettling, and marvel at practical effects that’ll make your flesh creep.

Dozens of panels and presentations are scheduled, including a deep-dive into the 95th anniversary of the Dracula and Frankenstein movies by writer Julian David Stone.

Stone said that the two classic movies have left a lasting impact.

“Dracula is a movie about supernatural horror..... and Frankenstein is about technological or man-made horror," he said. "You can just trace those two themes all the way forward to this past year with Sinners and Megan 2.0."

Stone first attended the convention in 2008, returning over the years as a fan, spectator and presenter.

“It’s just a terrific convention that celebrates all things horror,” Stone said. “There’s a lot of celebrities you can meet who were in these horror films and you can get pictures with them." He added that he’ll never forget when he met Carla Laemmle in 2010 — the last living cast member of the original 1931 Dracula.
