Regional health agency warns of increased risk of a disease outbreak after Venezuela’s twin earthquakes

Venezuela’s authorities say the death toll from twin earthquakes last month has risen to 3,889, as regional health agencies warn of an increased risk of disease.

Lawmaker Jorge Rodrigues said on Thursday at least 16,740 people had been injured and 17,907 displaced.

The Pan American Health Organization (PAHO) warned that displaced people across Venezuela’s northern coast, the area most affected by the tremors, are at risk of disease because of limited access to clean water and regular medical care.

“In the coming weeks, the greatest health risks may stem not only from injuries caused by the earthquakes, but also from disruptions to health services, overcrowded conditions, deficiencies in water and sanitation and reduced access to vaccination and routine healthcare,” PAHO’s director Jarbas Barbosa said.

The agency is working with Venezuela’s health ⁠ministry to improve vaccine access and trace any outbreaks of respiratory or digestive illnesses, especially in shelters set up for those who lost their homes.

The United Nations launched an appeal for roughly $300 million to assist 1.3 million people in urgent need of aid in Venezuela.

PAHO urged immediate disbursement of the remaining $15 million in requested emergency aid to repair damaged hospitals and to maintain basic sanitation in camps for the displaced to prevent a health emergency.

“Lethal Weapon” star Danny Glover has revealed he has been living with Alzheimer’s disease for years.

In an interview with NBC’s Lester Holt that aired on the “Today” show on Wednesday, the 79-year-old actor and activist opened up about living with the disease. According to People, he received his diagnosis in 2023, which was not long after he was awarded an honorary Oscar in 2022.

“I could live with it, in a sense,” Glover says of his condition, which has been affecting his movement, speech and memory. “I’m sure as it advances, things are going to be different and changing.”

A neurodegenerative disease, Alzheimer’s is a type of dementia that affects memory, thinking and behavior and worsens over time, according to the Alzheimer’s Assn. Holt reports that more than 7 million Americans over 65 are living with Alzheimer’s, with Black men suffering at a rate double the national average.

Glover and his family say the Hollywood icon is sharing his story now to “have ownership of his life” and to help remove the stigma around the disease.

“They’ve got my back,” Glover says of his family’s support.

Besides his portrayal of L.A. police Det. Roger Murtaugh in the “Lethal Weapon” film series, Glover is known for roles in movies including “Places in the Heart” (1984), “The Color Purple” (1985), “To Sleep With Anger” (1990), “Angels in the Outfield” (1994), “Dreamgirls” (2006) and “The Last Black Man in San Francisco” (2019). He’s also been a vocal advocate for social justice and humanitarian causes both in the U.S. and abroad.

He was the recipient of the Academy of Motion Picture Arts and Sciences’ Jean Hersholt Humanitarian Award in 2022.

“I don’t feel like it’s the end of my life,” he said in his interview with People about living with Alzheimer’s. “There’s work to do.”

THE Jam star Bruce Foxton has revealed he’s been diagnosed with Parkinson’s Disease.

The iconic bassist, 70, took to Facebook this evening to share the news with fans just days after cancelling two shows at short notice due to illness.

In his statement, he revealed the diagnosis came to light after side effects from his cancer treatment were investigated.

He said: “It’s no secret that I’ve undergone treatment for cancer and am still having scans on a regular basis to keep an eye on that.

“However, what you don’t know is that the cancer treatment in itself caused some significant issues for me and investigations into all of that uncovered the fact that I’m now facing a future living with Parkinson’s Disease…and I’m determined to do that as well as I possibly can.

“As anyone coping with this diagnosis will know it’s a huge shock, and it’s taking a long time to let that sink in and for me to accept that my body and mind are dealing with something completely out of my control.

“I have to manage the challenges I now face physically and mentally on a daily basis, and some days are better than others.”

Fans sent the musician their well-wishes in the comments.

One wrote: “Sorry to hear about all your health problems you need to do what is best for you and your family moving forwards.”

Another said: “All the best Bruce, your health is far more important than anything else and I am so sorry that you are having more health struggles. Look after yourself and I hope you enjoy many more years of happiness.”

Bruce cancelled his show in Kidderminster on Friday and postponed the following night’s show in Lincoln after high temperatures aggravated a chest infection.

The former Stiff Little Fingers musician formed From The Jam in 2007 with The Jam drummer Rick Buckler and new frontman Russell Hastings.

Original The Jam frontman Paul Weller was initially critical of the band playing the old hits but his stance softened over the years as his friendship with Foxton strengthened.

The trio were prolific on the touring circuit, thrilling mod fans young and old with the legendary band’s iconic hits such as The Eton Rifles and Going Underground.

Bruce underwent immunotherapy after a cancerous lymph node was found in 2023 and, the following year, he had knee replacement surgery.

The health issues took their toll and fans noticed he appeared to be struggling during shows in 2025, which eventually led to him retiring from From The Jam.

However, he scaled down his schedule and now performs with his All-Star band.

Bruce wears custom hearing aids due to hearing loss from 40 years on stage. He also has lived with tinnitus for years.

Chris Johnson, the former NFL running back who holds the record for most yards from scrimmage in a single season, has the degenerative neurological disorder amyotrophic lateral sclerosis, commonly known as ALS or Lou Gehrig’s disease.

Johnson shared the diagnosis during an interview with Michael Strahan that aired Monday on ABC’s “Good Morning America.” The 40-year-old father of four spoke in his own voice but didn’t use his mouth — instead, he used his eyes to trigger a device that generated sentences based on recordings Johnson made soon after he was diagnosed last year.

“It’s continued to progress much faster than I ever imagined,” Johnson said of the disease. “I want people to understand just how quickly ALS can attack your body. Just over a year ago, I was picking up my 7-year-old daughter so she’d make a wish with her birthday cake. Today, I couldn’t do that.”

There is currently no known treatment that stops or reverses ALS, according to the National Institute of Neurological Disorders and Stroke, and most people with disease die of respiratory failure within three to five years of noticing symptoms (although one in 10 survive a decade or more).

In addition to receiving the standard medication to help slow the disease’s progression, Johnson has been working with neurologist and leading ALS researcher Dr. Merit Cudkowicz. She told “Good Morning America” that Johnson has taken part in a clinical trial for a therapy “that decreases inflammation, and I think that helped him a lot.”

“At first, you’re in shock, then you realize you have two choices: You can give up, or you can fight,” Johnson said. “I chose to fight.”

Johnson’s wife Brittany told Strahan: “We’re still hopeful. We’re hopeful that a breakthrough will happen or … a miracle will happen.”

Selected by the Tennessee Titans at No. 24 in the 2008 draft, Johnson was an instant NFL star. He made the Pro Bowl in each of his first three seasons and was named the league’s offensive player of the year in 2009. Also that season, Johnson led the NFL with 2,006 rushing yards — earning the nickname CJ2K as one of only nine players to have rushed for 2,000 or more yards in a season — and set a record with 2,509 yards from scrimmage that still stands.

Johnson rushed for more than 1,000 yards in each of his six seasons with the Titans, then spent a year with the New York Jets and three more with the Arizona Cardinals before retiring after the 2017 season. He finished with 9,651 yards and 55 touchdowns rushing and 2,255 yards and nine touchdowns receiving.

Titans owner Amy Adams Strunk released a statement Monday morning after Johnson’s diagnosis was revealed.

“Learning this news is extremely difficult, and we will support Chris every step of the way throughout his journey,” she wrote. “We are holding him and his family close, and join our fans around the world in expressing our love for Chris.”

The Jets and Cardinals also released statements expressing their support for Johnson.

While Johnson’s body will no longer allow him to perform a task like gripping a cup, he said he wants people to know that with ALS, “your mind stays sharp.”

“People sometimes look at the physical disability and assume you’re not still the same person inside,” Johnson said. “I still think the same. I still dream. I still love my family. My body just doesn’t cooperate.”

COUNTRY legend Alan Jackson is preparing to take the stage one final time – but behind his emotional farewell has been a grueling 15-year battle with a degenerative nerve disease that has changed his life.

The music icon was diagnosed with Charcot–Marie–Tooth disease in 2011, but kept it private for a decade before publicly revealing the condition in 2021.

The hereditary disorder causes nerve damage, mostly in the arms and legs, leading to muscle weakness, loss of sensation, balance problems, and difficulty walking.

While it’s not typically considered fatal, it has led to deaths – including 911: Nashville actress Isabelle Tate, who passed away from the disease in 2025. 

Behind Alan’s final curtain call is a brutal health battle that has quietly followed him for more than 15 years.

“It’s been affecting me for years,” he said in 2021 while first revealing the diagnosis on the Today Show. 

“And it’s getting more and more obvious. I know I’m not going to be able to tour like I have.”

Alan, 67, also revealed the diagnosis runs in his family, explaining: “I have this neuropathy and neurological disease. It’s genetic that I inherited from my daddy.”

The disease affects balance, coordination, and muscle control – making even simple movement more difficult as it progresses.

For a performer known for commanding massive stages and playing live instruments, the condition has made touring especially challenging.

Alan has opened up about his struggles, saying: “I know I’m stumbling around on stage. And now I’m having a little trouble balancing, even in front of the microphone.” 

Over the years, Alan has continued performing despite worsening symptoms, though he acknowledged the disease has forced him to adjust.

“I don’t feel comfortable,” he said of performing while navigating the disorder. “It’s going to disable me eventually.”

While Charcot-Marie-Tooth does not always directly impact life expectancy, there is no cure, according to the Mayo Clinic. 

Treatment typically focuses on managing symptoms through physical therapy, braces, pain management, and mobility support.

Still, Alan said he has refused to let the diagnosis define him, pushing through multiple tours and live shows while accepting that the end of his road on stage would come in the nearer future. 

Now, the singer is set for his final full-length concert, Last Call: One More for the Road – The Finale, on June 27 at Nissan Stadium. 

The massive send-off will bring Alan back to Nashville – the city where his career first took off – and feature an all-star lineup including Luke Bryan, Eric Church, Luke Combs, Miranda Lambert, George Strait, Carrie Underwood, Lainey Wilson, Little Big Town, Thomas Rhett, Jake Owen, Jon Pardi, and Lee Ann Womack.

The sold-out show will begin in the early evening and rock on all night, with more than 50,000 fans expected in attendance.

And for those who can’t make it in person, the historic farewell will be filmed for an NBC primetime special titled Alan Jackson: The Last Show, before streaming the following day on Peacock.

For the country crooner, it’s a full-circle moment – and the closing chapter of one of music’s most enduring careers.

The Georgia native has sold more than 75 million records worldwide, with a staggering 35 Number 1 hits and 50 Top 10 singles to his name. 

He’s won two Grammy Awards, 16 CMA Awards, 17 ACM Awards, and was inducted into the Country Music Hall of Fame in 2017.

The singer is also a member of the Grand Ole Opry and has long been praised for helping preserve traditional country music through hits like Chattahoochee, Livin’ on Love, Remember When, and Where Were You (When the World Stopped Turning).

Alan has long credited his family as the backbone of his decades-long career.

He has been married to his high school sweetheart, Denise Jackson, since 1979 after the pair met as teenagers in their hometown of Newnan, Georgia.

Denise famously helped launch his music career after running into country legend Glen Campbell on a flight and passing along Alan’s demo – a moment that helped change their lives forever.

Together, Alan and Denise share three daughters: Mattie Jackson Smith, Alexandra Jane Bradshaw, and Dani Grace Jackson.

WASHINGTON — While millions of soccer fans cheer or groan over World Cup matches spanning North America, health officials are on high alert for germs.

A heat wave may be the most obvious health threat. But infectious diseases can spread in a crowd, and experts are scrutinizing wastewater, hospital visits, even social media for any signs that an outbreak might be brewing.

Measles, one of the most contagious diseases, is among the top concerns, sparking a warning this week from the Pan American Health Organization, PAHO. With a nearly six-week stretch of packed stadiums, bars and tourist sites in 16 cities, officials are on the lookout for a long list of infections, from the stomach bug norovirus to mosquito-borne dengue fever.

“This is truly a marathon,” said Palak Raval-Nelson, Philadelphia’s health commissioner.

The mass gatherings come at a tense moment for budget-strapped health agencies in the U.S. The Centers for Disease Control and Prevention, hit hard by Trump administration staffing cuts, already was grappling with a growing Ebola outbreak in central Africa and a cruise ship hantavirus outbreak. While CDC officials have advised state and local health departments behind the scenes, it’s expected World Cup disease surveillance dashboard still was “in final development” days before games began, according to the Department of Health and Human Services.

“Our public health professionals are pretty stretched,” said global health specialist Rebecca Katz of Georgetown University, who is leading an unusual new hub to help.

At the Health Security Operations Center, a joint effort between Georgetown and MedStar Health, workers are analyzing data from around the country so they can alert health authorities, even emergency rooms, to any early signs of trouble. The center is issuing daily “situation reports” about disease trends around World Cup host cities and team base camps to several hundred local and federal public health groups, emergency management and hospital officials and others who’ve signed up.

“It’s important that we don’t become alarmist,” said MedStar emergency medicine specialist Dr. Shane Kappler. “We’re trying to be the insurance policy.”

Measles is a top concern for potential World Cup spread

Already more than 2,000 people in the U.S. have come down with measles this year, nearly as many as during all of last year, according to the CDC. Patients can spread measles before the rash appears and they realize they’re sick. Not too long ago, the U.S. seldom saw measles except from international travel by unvaccinated people.

Now with frequent U.S. outbreaks, “actually a lot of our international partners are worried about measles being exported to them after the games,” said Georgetown’s Katz.

Measles is spreading in Canada, too, and has exceeded 11,000 cases in Mexico, according to PAHO. It’s urging soccer fans to be sure they’re vaccinated, with a health campaign saying a single measles patient can spread the virus to up to 18 unprotected people.

Is Ebola a concern at the World Cup?

Brown University’s Dr. Craig Spencer, who survived Ebola while working in the West Africa outbreak over a decade ago, said he’s repeatedly asked about the risk of Ebola during the World Cup — but “for me, Ebola is not the No. 1 or No. 2 or even No. 3 threat.”

“I am concerned about importation of measles, I am much more concerned about the importation of other infectious threats that may not seem as scary to us as Ebola,” Spencer said.

Many health experts agree that the risk of Ebola spreading in the U.S. is very low. That’s partly because of government travel screenings and restrictions on people recently in outbreak-affected areas. Moreover, Ebola spreads by contact with bodily fluids from someone showing symptoms, not through the air like measles or respiratory viruses.

“One fortunate thing about this virus is you’re most contagious when you’re really quite ill. It’s not like COVID, where you could be sitting next to someone who doesn’t even know they’re infected and perhaps contract the virus,” said Jennifer Nuzzo, director of Brown’s Pandemic Center.

How to spot brewing diseases

There’s precedent for germs invading major sporting events. Canadian scientists linked a community measles outbreak to the 2010 Olympics in Vancouver, and clusters of norovirus had to be contained during the Olympics this year in Milan and in 2018 in South Korea.

One way to detect signs of trouble: People with certain viral or bacterial infections shed genetic material that sophisticated testing of wastewater can spot. For example, measles can appear in wastewater days before an emergency room sees its first patients.

A recent surveillance reports from Katz’s center note that wastewater testing recently found diarrhea-causing rotavirus, hepatitis A and norovirus in some parts of the U.S., something to watch as soccer crowds arrive.

In Dallas, officials ramped up wastewater screening including at the international airport, casting a wide net rather than looking for specific illnesses, said Dr. Phil Huang, director of Dallas County Health and Human Services.

His team also is enhancing the usual mosquito testing, checking not just for West Nile virus that regularly spreads in the U.S. but for viruses more common in other countries like dengue and chikungunya.

Public health officials have been preparing for months, said Philadelphia’s Raval-Nelson, including with mock emergency drills and communications with counterparts around the country.

“I don’t want to send a message that there’s one key thing,” she said. “We have the frameworks in place to carry out what we need to.”

WASHINGTON — President Trump on Friday gave his endorsement to a January study by the Department of Health and Human Services that calls for cutting the number of vaccines recommended for every American child.

An executive order from Trump directs federal agencies to align their policies behind the study, which recommended an overhaul long called for by Health Secretary Robert F. Kennedy Jr. The study found that the United States recommends more childhood vaccines than many peer nations.

The Trump administration previously moved to narrow the number of recommended childhood vaccines in response to the report, but the move was blocked by a federal judge in Massachusetts. The administration is appealing the decision.

The study recommends vaccinating all children against 11 diseases. Several others would be recommended only for high-risk groups or when doctors recommend them in what’s called “shared decision-making.” That includes vaccines for flu, rotavirus, hepatitis A, hepatitis B, some forms of meningitis and RSV.

Trump’s order adds weight behind the study at a time when the administration had appeared to be trying to shift focus away from Kennedy’s more contentious vaccine policies and toward topics with more widespread support among medical professionals, such as healthful eating.

The order directs the Centers for Disease Control and Prevention to review the study and “take any appropriate steps” to update its vaccine recommendations. It says the CDC should “provide maximum flexibility to parents and doctors” and directs agencies to make sure all actions, regulations and funding are aligned with the study.

The order adds that any changes should ensure that Americans retain their current access to vaccines.

States, not the federal government, have the authority to require vaccinations for schoolchildren. While CDC requirements often influence those state regulations, some states have begun creating their own alliances to counter the Trump administration’s guidance on vaccines.

Trump directed the Department of Health and Human Services to carry out the study in December.

Kennedy is a longtime activist against vaccines and has sought ways to inject his skepticism about the shots into national guidance, running counter to the overwhelming consensus of medical experts. Last year, he announced the CDC would no longer recommend COVID-19 vaccines for healthy children and pregnant women, though public health experts said they saw no new data to justify the change.

Last June, he fired a 17-member CDC vaccine advisory committee and later installed several of his own replacements, including vaccine skeptics.

The January report found that vaccine recommendations for American children had increased in recent decades. It also highlighted countries where no vaccines are required to attend school.

This remote island was once a thriving town – but now all that remains are ruins.

Hidden away in a far-flung Scottish archipelago lie the remains of a once-bustling settlement, deserted by all who called it home. The island of Hirta in the Outer Hebrides was occupied for 2,000 years, but during the 1930s, its final inhabitants evacuated due to health concerns.

It’s so isolated that it’s often omitted from maps altogether and can only be reached by boat – weather permitting.

It’s one of 40 islands in the St Kilda archipelago and now hosts the world’s largest gannet colony alongside some of the biggest puffin populations. During its inhabited years, islanders depended heavily on these seabirds – not merely for sustenance but for commerce.

They traded every component of the birds from feather to flesh.

Today, the population has vanished but a handful of military structures remain scattered across the island, overshadowing the crumbling stone cottages that once housed the community.

The structures line what was formerly Hirta’s main thoroughfare – now occupied solely by sheep, reports the Express.

Existence there was extraordinarily harsh, with severe weather conditions and scarce resources available.

To stay warm throughout the lengthy winters, inhabitants would bring livestock inside their basic stone dwellings and allow the waste from cattle and sheep to serve as insulation.

At its height in 1851, Hirta was inhabited by 112 people but this number rapidly dwindled over subsequent years.

Medical provision on the island had always been severely restricted, and as visitors began arriving on the isolated outpost as tourists, they introduced unfamiliar illnesses that the islanders were poorly prepared to combat.

During the 1930s, following the death of a young woman from appendicitis and pneumonia — conditions that might have been treatable on the mainland — the inhabitants of Hirta took the difficult decision to abandon the island.

The residents were evacuated by vessel in August that year and transported to mainland Scotland.

Following their local custom, islanders left a plate of oats and an open bible in every dwelling before stepping aboard the ship.

The final surviving former inhabitant of St Kilda, who was eight years old when the island was evacuated, passed away in 2016.

Bill Cassidy’s roles as a lawmaker, a doctor and a political candidate will collide on Wednesday as he questions Health Secretary Robert F. Kennedy Jr. in two high-stakes Senate hearings.

The Louisiana Republican chairs one of the Senate committees that oversees Kennedy’s department and sits on another, giving him two chances to interrogate the secretary about his plans for an agency responsible for public health programs and research. As a doctor, Cassidy has clashed with Kennedy’s anti-vaccine ideas even though he provided crucial support for the health secretary’s nomination last year.

At the same time, Cassidy is fighting for his political future in next month’s primary in Louisiana, where President Trump has endorsed one of his opponents in an unusual attempt to oust a sitting senator from his own party.

How Cassidy handles the hearings could affect his chances at a pivotal moment of his reelection campaign and set the tone for how Congress oversees the nation’s health agenda at a time of rampant distrust and misinformation.

Cassidy hasn’t faced Kennedy in public since September. In the subsequent months, Kennedy has attempted a dramatic rollback of vaccine recommendations that, if not blocked by an ongoing lawsuit, could undermine protections against diseases like flu, hepatitis B and RSV.

After a backlash, Kennedy has also pivoted to spending more time talking about less controversial topics like healthy eating — albeit with his own spin, including sharing exaggerated claims that various ailments can be cured by diet alone.

Cassidy will have to decide on Wednesday whether to grill Kennedy on vaccines, an issue deeply important to him, or put their differences aside and prioritize loyalty to the Trump administration.

“He’s taken a risk showing any sort of resistance to RFK,” said Claire Leavitt, an assistant professor at Smith College who studies congressional oversight. “He may pay an electoral price for that.”

Cassidy has long advocated for vaccines

Cassidy has spent years walking a political tightrope. He’s one of the few Republican senators who voted to convict Trump during an impeachment trial after the Jan. 6, 2021, attack on the U.S. Capitol.

As a liver doctor, he advocated for babies to receive hepatitis B vaccines shortly after birth, a step that could have prevented the disease in his patients. But when Trump nominated Kennedy, a longtime anti-vaccine activist, Cassidy supported him. He did so after securing various commitments, including that Kennedy would work within the current vaccine approval and safety monitoring system and support the childhood vaccine schedule.

The vote for Kennedy did not appear to mollify Trump. The president endorsed U.S. Rep. Julia Letlow, one of Cassidy’s two primary opponents.

Cassidy also faces opposition from Kennedy’s allies in the “Make America Healthy Again” movement, a group that includes both anti-vaccine activists and a wide variety of other crusaders for health and the environment. The MAHA PAC, aligned with Kennedy, has pledged $1 million to Letlow’s campaign. While the organization hasn’t publicly said so, some have questioned whether the support is partly in retaliation against Cassidy for criticizing Kennedy’s vaccine policy agenda.

“I’m not really sure what MAHA’s beef is,” Cassidy told reporters earlier this month. “Let me point out that I am the reason that Robert F. Kennedy is now the secretary of HHS. He would not have gotten there otherwise.”

Cassidy argues that he has “strongly supported” the MAHA agenda, especially when it comes to the fight against ultraprocessed foods. However, the physician-turned-senator acknowledged that he and MAHA have “disagreed on vaccines.”

“We’ve seen, frankly, that I am right,” Cassidy added, pointing to recent measles-related deaths of children who were not vaccinated.

At a hearing in September, he slammed Kennedy’s decision to slash funding for mRNA vaccine development. He interrogated Kennedy over his attempt to replace members of a vaccine committee, suggesting the new members could have conflicts of interest. He also raised concerns that Kennedy’s vaccine policy decisions could be making it harder for Americans to get COVID-19 shots.

Later that month, Cassidy convened a hearing featuring former U.S. Centers for Disease Control and Prevention Director Susan Monarez, who was ousted by Kennedy less than a month into her tenure after they clashed over vaccine policy, and former CDC Chief Medical Officer Debra Houry, who resigned in August citing an erosion of science at the agency.

“I want to work with the president to fulfill his campaign promise to reform the CDC and Make America Healthy Again. The president says radical transparency is the way to do that,” Cassidy said at the time.

Experts say Cassidy’s vaccine stance might not hurt him

Political consultants said they expect Cassidy’s primary opponents, Letlow and Louisiana Treasurer John Fleming, to seize on any sound bites from Wednesday’s hearings that can make Cassidy seem at odds with the Trump administration.

But Dorit Reiss, a vaccine law expert at UC Law San Francisco, said the political risk of advocating for vaccines may not be as strong among Republicans as some people assume.

“He’s probably not alienating voters by focusing on the issue and calling it out,” she said.

Louisiana political consultant Mary-Patricia Wray said she thinks most diehard MAHA voters already know who they are voting for, and it’s probably not Cassidy.

Instead, she said, he may still be able to appeal to Democrats who switch their party registration to vote in the primary, as well as a wide swath of still-undecided Republican voters who care about the same health care affordability issues he advocates for every day in Congress.

“If I was advising Bill Cassidy, I would tell him your goal here is not to get out unscathed,” Wray said. “Your goal is to prove that your consistency on issues regarding public health is an asset in your campaign, not a detriment.”

Election outcome will shape future oversight of HHS

Also at stake if Cassidy doesn’t make it to November’s general election is what will happen to his responsibility to oversee the massive U.S. Department of Health and Human Services as the chair of the Senate Health, Education, Labor and Pensions committee.

Leavitt, the Smith College professor, said seniority typically plays the most important role in who chairs Senate committees. She said another Republican in today’s increasingly hyperpartisan Congress may not be as willing as Cassidy to check Kennedy’s power.

Reiss, the vaccine law expert, said she wishes Cassidy had done more hearings or introduced legislation to rein in Kennedy. And she said the senator bears the blame for allowing Kennedy to bring unfounded vaccine fears into the government in the first place.

“His original sin, of course, was voting for Kennedy at all,” Reiss said.
