Vaccine committee votes to scrap universal hepatitis B shots for newborns despite outcry from children’s health experts

The committee advising the Centers for Disease Control and Prevention on vaccine policy voted on Dec. 5, 2025, to stop recommending that all newborns be routinely vaccinated against the hepatitis B virus – undoing a 34-year prevention strategy that has nearly eliminated early childhood hepatitis B infections in the United States.

Before the U.S. began vaccinating all infants at birth with the hepatitis B vaccine in 1991, around 18,000 children every year contracted the virus before their 10th birthday – about half of them at birth. About 90% of that subset developed a chronic infection.

In the U.S., 1 in 4 children chronically infected with hepatitis B will die prematurely from cirrhosis or liver cancer.

Today, fewer than 1,000 American children or adolescents contract the virus every year – a 95% drop. Fewer than 20 babies each year are reported infected at birth.

I am a pediatrician and preventive medicine specialist who studies vaccine delivery and policy. Vaccinating babies for hepatitis B at birth remains one of the clearest, most evidence-based ways to keep American children free of this lifelong, deadly infection.

What spurred the change?

In September 2025, the Advisory Committee on Immunization Practices, or ACIP, an independent panel of experts that advises the CDC, debated changing the recommendation for a dose of the hepatitis B vaccine at birth, but ultimately delayed the vote.

This committee regularly reviews vaccine guidance. However, since Secretary of Health and Human Services Robert F. Kennedy Jr. disbanded the entire committee and handpicked new members, its activity has drastically departed from business as usual. The committee has long-standing procedures for evaluating evidence on the risks and benefits of vaccines, but these procedures were not followed in the September meeting and were not followed for this most recent decision.

The committee’s new recommendation keeps the hepatitis B vaccine at birth for infants whose mothers test positive for the virus. But the committee now advises that infants whose mothers test negative should consult with their health care provider. Parents and health care providers are instructed to weigh vaccine benefits, vaccine risks and infection risks using “individual-based decision-making” or “shared clinical decision-making.”

The hepatitis B vaccine has an outstanding safety record and has been administered to billions of infants at birth.

On the surface, this sounds reasonable. But while parents have always been free to discuss benefits and risks with their health care providers to make a decision on what’s best for their child, this change is not based on any new evidence, and it introduces uncertainty into a recommendation that has long been clear.

As a doctor, I am already seeing this uncertainty play out in the clinic. I recently had new parents ask to postpone the hepatitis B vaccine until adolescence because they believed federal health leaders had evidence that people only become infected through sexual activity or contaminated needle use.

After a brief conversation, they came to understand that this was inaccurate — children can be infected not only at birth but also through routine household or child care exposures, including shared toothbrushes or even a bite that breaks the skin. In the end, they chose to vaccinate, but this experience highlights how easily well-intentioned parents can be misled when guidance is not clear and consistent.

Why the CDC adopted universal hepatitis B shots

Hepatitis B is a virus that infects liver cells, causing inflammation and damage. It is spread through blood and bodily fluids and is easily transmitted from mother to baby during delivery.

The hepatitis B vaccine has been available since the early 1980s. Before 1991, public health guidance recommended giving newborns the hepatitis B vaccine only if they were at high risk of being infected – for example, if they were born to a mother infected with hepatitis B.

That targeted plan failed. Tens of thousands of infants were still infected each year.

Some newborns were exposed when their mothers weren’t screened; others were exposed after their mothers were infected late in pregnancy, after their initial screening. And like any lab test, the screening can have false negative results, be misinterpreted or not be communicated properly to the baby’s care team.

Recognizing these gaps, in 1991 the CDC recommended hepatitis B vaccination for every child starting at birth, regardless of maternal risk.

The U.S. adopted a policy of vaccinating all babies from birth because the number of people with hepatitis B infections was, and remains, relatively high, and because many mothers do not receive prenatal care, so their infections go undetected.

Meanwhile, in some European countries, like Denmark, only babies with certain risk factors receive the vaccine at birth. That’s because in those countries, hepatitis B infections are much less prevalent and pregnant mothers are more widely tested due to universal health care. Due to these differences, that approach is not effective in the United States. In fact, most World Health Organization member countries do recommend a universal birth dose.

Vaccinating at birth

The greatest danger for infants contracting hepatitis B is at birth, when contact with a mother’s blood can transmit the virus. Without preventive treatment or vaccination, 70% to 90% of infants born to infected mothers will become infected themselves, and 90% of those infections will become chronic. The infection in these children silently damages their liver, potentially leading to liver cancer and death.

About 80% of parents choose to vaccinate their babies at birth. If parents choose to delay vaccination due to this new recommendation, it will leave babies unprotected during this most vulnerable window, when infection is most likely to lead to chronic infection and silently damage the liver.

A research article published on Dec. 3, 2025, estimates that if only infants born to mothers infected with hepatitis B received the vaccine, an additional 476 perinatal hepatitis B infections would occur each year.

The hepatitis B vaccines used in the U.S. have an outstanding safety record. The only confirmed risk is an allergic reaction called anaphylaxis that occurs in roughly 1 in 600,000 doses, and no child has died from such a reaction. Extensive studies show no link to other serious conditions.

How children get exposed to hepatitis B

Infants and children continue to be vulnerable to hepatitis B long after birth.

Children can become infected through household contacts or in child care settings by exposures as ordinary as shared toothbrushes or a bite that breaks the skin. Because hepatitis B can survive for a week on household surfaces, and many carriers are unaware they are infected, even babies and toddlers of uninfected mothers remained at risk.

Full protection against hepatitis B requires a three-dose vaccine series, given at specific intervals in infancy. Anything short of the full series leaves children vulnerable for life.

In addition to changing the birth dose recommendation, the committee is now advising parents to consult with their health care provider about checking children’s antibody levels after one or two doses of the vaccine to determine whether additional doses are needed. While such testing is sometimes recommended for people in high-risk groups after they get all three doses to confirm their immune system properly responded to the vaccine, it is not a substitute for completing the series.

The recommendation for all babies to receive the vaccine at birth and for infants to complete the full vaccine series is designed to protect every child, including those who slip through gaps in maternal screening or encounter the virus in everyday life. A reversion to the less effective risk-based approach threatens to erode this critical safety net.

Pentagon to integrate Elon Musk’s AI chatbot Grok, exploring military data and innovation amid AI controversies.


Defense Secretary Pete Hegseth announced that Elon Musk’s AI chatbot Grok will soon be integrated with the Pentagon’s networks.

The move aims to harness military data to develop advanced AI technology, despite recent controversies surrounding Grok’s content generation. This integration signals a bold step toward combining commercial AI tools with national defence systems.

Dr Karen Sutherland from UniSC explores the implications of this partnership. We discuss how Hegseth’s approach to AI differs from the Biden administration’s framework, the measures in place to ensure responsible use, and the limitations on Grok’s image generation capabilities.

We also examine the potential risks and international reactions, as well as Hegseth’s vision for innovation within the military. From civil rights considerations to prioritising key technologies, this story highlights the complex balancing act of AI in modern defence.

U.S. pushes Latin American dominance

Published

on

What lies ahead for Latin America after the Venezuela raid?

Nicolas Forsans, University of Essex

The Trump administration has justified the recent capture of Venezuelan leader Nicolás Maduro as a law enforcement operation to dismantle a “narco‑state”. It also claimed it would break Venezuela’s ties to China, Russia and Iran, and put the world’s largest known oil reserves back under US‑friendly control.

This mix of counter‑narcotics, great power rivalry and energy security had already been elevated to a central priority by the administration in its national security strategy. Published in late 2025, the document announced a pledge to “reassert and enforce American preeminence in the western hemisphere” and deny “strategically vital assets” to rival powers.

Donald Trump has referred to this hemispheric project as the “Donroe doctrine”, casting it as a revival of the Monroe doctrine policy of the 19th century through which the US sought to stop European powers from meddling in the Americas. He seems to be seeking to tighten the US grip on Latin America by rewarding loyal governments and punishing defiant ones.

If Venezuela is the first test case of the Donroe doctrine, several other Latin American countries now sit squarely in Washington’s crosshairs. The most immediate target is Cuba, which the US has opposed since 1959 when communist revolutionary Fidel Castro overthrew a US-backed regime there.

Trump and his secretary of state, Marco Rubio, have openly hinted that Cuba could be Washington’s next target. They have described Cuba as “ready to fall” after the loss of Venezuelan oil and have boasted that there is no need for direct intervention because economic collapse will finish the job.

Cuba is enduring its worst crisis since 1959. Blackouts now regularly last up to 20 hours, real wages are collapsing and roughly 1 million Cubans have fled the country since 2021. This is all happening as Venezuelan crude oil is being redirected under US control.

For over two decades, Venezuela has provided Cuba with fuel and financing in exchange for doctors, teachers and security personnel – 32 of whom were killed in the US capture of Maduro, according to the Cuban government. Strangling Cuba’s remaining lifelines may well be enough to topple the government there without US forces needing to fire a single shot.

It is possible that Mexico will also soon come under fire. Mexico has quietly become Cuba’s main oil supplier, shipping roughly 12,000 barrels per day in 2025 to account for about 44% of the island’s crude imports. This is unlikely to please the Trump administration, which has recently renewed its threats to “do something” about Mexican drug cartels.

The raid in Venezuela’s capital, Caracas, took six months of meticulous planning and required an extraordinary amount of resources. So it is unrealistic to expect similar raids on other Latin American countries. However, targeted military strikes cannot be excluded.

Speaking on Fox News’s “Hannity” show on January 8, Trump said: “We are going to start now hitting land with regard to the cartels. The cartels are running Mexico.” He did not provide further details about the plans.

Mexico’s president, Claudia Sheinbaum, is trying to construct protective buffers. She has combined condemnation of the raid on Caracas with intense cooperation with the US on migration and security. This includes a deal for Mexico’s navy to intercept suspected drug-running boats near its coastline before US forces do.

But as part of a strategy that pushes US dominance of Latin America, Trump has already floated classifying Mexico’s cartels as terrorist organisations and the fentanyl they traffic across the border as a weapon of mass destruction. These are legal framings that could be used to justify strikes on Mexican soil in the name of counter-narcotics in the near future.

Trump’s other targets

Colombia, historically Washington’s closest military ally in South America, has flipped from “pillar” to possible target. The country’s president, Gustavo Petro, has been one of the loudest critics of the Venezuela raid. He called it an “abhorrent violation” of Latin American sovereignty committed by “enslavers”, adding that it constituted a “spectacle of death” comparable to Nazi Germany’s 1937 carpet bombing of Guernica in Spain.

Trump, who imposed sanctions on Petro and his family in October, responded by labelling the Colombian president a “sick man who likes making cocaine and selling it to the United States”. He then mused that a Venezuela‑style operation in Colombia “sounds good to me” before a hastily arranged phone call and White House invitation dialled back the immediate threat.

How long the conciliation between the two men lasts remains to be seen. Colombia has entered a heated presidential campaign season in which Trump’s remarks are already being read as an attempt to tilt the race, much as his interventions shaped recent contests in Argentina and Honduras.

Further down the hierarchy, Nicaragua’s government will also have watched events unfold in Venezuela with terror. Long treated in Washington as part of a trilogy of dictatorships with Cuba and Venezuela, Nicaragua features in US indictments against Maduro as a transit point for cocaine flights. Nicaragua was also recently designated by the US as a key drug‑transit country.

The unusually cautious statement on the Venezuela raid by Nicaraguan presidential couple Daniel Ortega and Rosario Murillo, as well as the rapid reinforcement of the presidential compound in the capital Managua, suggest a regime that knows it could be next in line should Trump choose to extend his “narco‑terrorism” narrative.

Trump appears to be turning longstanding US concerns – drugs, migration and interference by other major powers – into a flexible toolbox for coercion in Latin America. Countries that defy Washington or host its rivals risk being framed as security threats, stripped of economic lifelines and, possibly, targeted militarily.

Those that keep their heads down may avoid immediate punishment. But this comes at the price of treating hemispheric dominance as a fact of life rather than a doctrine to be resisted.The Conversation

Antisemitism debate a political minefield for royal commission

Published

on

The antisemitism debate is already a political minefield. The royal commission must rise above it

Matteo Vergani, Deakin University

What we currently know about antisemitism in Australia is pieced together from a fragmented body of information produced by community organisations, researchers and law enforcement. And it is largely interpreted and translated to the public through news reporting.

Through this reporting, Australians have learned that organised criminal groups were involved in targeting Jewish communities and foreign actors also played a role.

At the same time, some data on antisemitic incidents released by security agencies has been incorrect. Other statistics produced by community organisations has been publicly challenged.

Researchers like myself have also produced data on antisemitic incidents, but this is limited in many ways.

In a nutshell, the picture of what constitutes antisemitism and how and why it has spiked in recent years is far from being clear.

This lack of clarity matters. Without a reliable understanding of what happened in the lead-up to the Bondi terror attack, which data can be trusted, and how different forms of antisemitism intersect, Australia cannot fully grasp how it reached a point where Jewish Australians were murdered at a public religious gathering.

Shedding light on this problem will be difficult, but it is essential to understand both the scale of the problem and how to respond.

Potential for more divisiveness

The royal commission established by Prime Minister Anthony Albanese is designed to address many of these unresolved issues.

As set out in its terms of reference, it will examine the nature and prevalence of antisemitism in Australia and assess how it can be more effectively addressed. It will also:

  • Review the responses of security and law enforcement agencies
  • Investigate what happened before, during, and after the Bondi attack
  • develop recommendations aimed at strengthening social cohesion.

Social cohesion and national consensus are the stated end goals of the entire exercise. Yet, the context in which the commission is operating is highly volatile. There is a real risk that rather than repairing social cohesion, the process itself could damage it.

This risk comes from the heavy political pressure now attached to the royal commission and from the way some political actors are using it as a weapon in broader political battles, including attacks on the government.

The antisemitism debate is already a political minefield. And the commission has entered that terrain from its first day.

The decision to acknowledge the International Holocaust Remembrance Alliance’s definition of antisemitism in the terms of reference is likely to be used by some to delegitimise the commission altogether. Critics argue the definition can be used to silence legitimate criticism of Israel, while supporters say it draws a necessary line between political critique and antisemitic tropes.

At the same time, some politicians have questioned the appointment of Former High Court justice Virginia Bell to head the commission, which could also undermine the credibility of the inquiry.

As a result, the commission is already inflaming existing political tensions. This is deeply unfortunate because it makes the task harder for those who are genuinely focused on understanding antisemitism, responding to it effectively, and improving the safety and well-being of Jewish Australians.

Why the Christchurch royal commission was successful

Royal commissions carry strong symbolic weight. They are often implemented when something has gone badly wrong, and the social fabric feels strained. The aim is to restore trust and provide a clear public account of what happened and why.

A useful point of comparison is the royal commission that followed the Christchurch terrorist attack in New Zealand. The inquiry led to wide-ranging reforms, including changes to firearms laws, counter-terrorism frameworks, approaches to social cohesion and inclusion, hate crime and hate speech legislation, and improved support for victims and witnesses.

It also contributed to the creation of the Christchurch Call to eliminate terrorist and violent extremist content online. This global initiative involving governments and technology companies has been successful in limiting the spread of terrorist and violent extremist material.

However, the political and social climate in New Zealand at the time was very different. There was a stronger sense of national unity and far less public contestation about what constituted hate. The attack was also not entangled with an ongoing and deeply polarising international conflict.

In Australia, the context is far more charged. The war in Gaza continues to divide public debate, regularly spilling into domestic politics.

It’s worth noting that antisemitic attacks have not stopped after Bondi. There was a firebombing less than two weeks later. This makes the task of using a royal commission to calm tensions and rebuild trust significantly harder.

Many pieces to the puzzle

Despite these difficulties, the commission matters now more than ever. Jewish Australians need answers, and the broader public deserves to understand what actually happened.

At present, the picture of what has caused rising antisemitism and the Bondi attack is confused. Public sentiment on the war, organised crime, foreign actors and terrorist ideology all appear to intersect, but how they connect remains unclear.

Different security agencies, researchers, and community organisations hold different pieces of evidence. Without bringing these strands together, Australians cannot fully understand the problem, let alone work out how to prevent it from happening again.

The path ahead will be difficult and exposed to disruption. One obvious challenge is the risk of further attacks while the inquiry is underway. Any new incident would complicate the process.

If, for example, an attack occurred that was shown to involve formal training or links to a terrorist organisation, serious questions would arise about whether the commission’s terms of reference remain adequate, or whether additional investigative processes would be required.

The most important test will come at the end. The commission’s recommendations must be acted on, regardless of which party is in government. That follow-through is what determines whether a royal commission produces real change or becomes just a symbolic exercise.

Meeting this test will require political restraint and maturity. It will mean resisting the temptation to turn the commission into a tool for partisan conflict and instead treating it as a shared national effort to protect communities and restore trust.The Conversation
