Hepatitis vaccines credited as life-saving for Alaska children may be upended

Western Alaska, where almost all the residents are Indigenous, used to have the world’s highest rate of childhood liver cancer caused by hepatitis B. After decades of screenings and vaccinations, that problem has been eliminated; since 1995, only one person under the age of 30 has been diagnosed with hepatitis-caused cancer.

Now the Trump administration is seeking to end one of the key tools credited with accomplishing that goal: hepatitis B vaccinations of newborns.

The federal Advisory Committee on Immunization Practices on Friday voted to drop a longstanding recommendation for universal hepatitis vaccines for newborns. That is in accordance with the controversial views of U.S. Health Secretary Robert F. Kennedy Jr., a vaccine skeptic who fired all members of the previous committee and appointed like-minded members to replace them.

Current federal childhood hepatitis B vaccination guidelines recommend one dose of the vaccine at birth, followed by additional doses at intervals through 18 months. The recommendation for newborn vaccinations has been in place since 1991.

The advisory committee, part of the U.S. Centers for Disease Control and Prevention, determined that children under 2 months should not be vaccinated unless their mothers are infected or could be infected by hepatitis B.

Some vaccine critics in the administration, including Kennedy and President Donald Trump themselves, argue — contradicting medical experts and years of medical research — that hepatitis B vaccines for young children are unnecessary, claiming that it is spread primarily or exclusively through adult behavior like sex and sharing of needles for illegal drug use.

“Hepatitis B is sexually transmitted. There’s no reason to give a baby that’s almost just born hepatitis B. So I would say wait till the baby is 12 years old and formed and take hepatitis B,” Trump said at a Sept. 22 news conference.

Those claims are false, said Dr. Brian McMahon, medical and research director of the liver and hepatitis program at the Alaska Native Tribal Health Consortium.

There is no credible evidence of a link between the vaccine and autism of any other health problem, McMahon said.

And sexual transmissions accounted for only a tiny percentage of Alaska’s hepatitis B cases, he said.

Aside from mother-to-infant transmissions, which occur during childbirth, hepatitis B was predominantly spread in Western Alaska through normal daily activities. That is because, unlike the HIV virus or other hepatitis viruses, the hepatitis B virus can live for seven days on surfaces in schools and homes, like tables and personal-grooming items.

“The virus can be found all over, on school luncheon tabletops, counters and homes,” McMahon said. “Kids have open cuts and scratches from bug bites or anything else, and then they shed millions of particles of the virus on environmental surfaces. And then another kid comes along with an open cut or scratch.”

Such risks are exacerbated in rural Alaska, he said, where homes can be crowded and people pursue traditional subsistence lifestyles with a lot of outdoor activities.

“They’re hunting, fishing, cutting up meat, et cetera, and mosquito bites are real prominent,” he said.

Nationally, only 12.6% of chronic hepatitis B cases recorded from 2013 to 2018 were attributable to sexual transmission, according to a 2023 CDC study. Transmissions of all forms of hepatitis, including hepatitis B, are possible through contact sports like football, rugby and hockey, researchers have found.

Alaska’s disease and vaccination success

Before the past decades of vaccination and screening, hepatitis B was so prevalent in Western Alaska that it was classified as endemic there. It was the only part of the United States with such a classification. In some villages, 20% to 30% of the residents were infected, McMahon said.

Geography and ancient migration patterns accounted for historically high rates of the disease in Western Alaska, as well as other Indigenous regions of the Arctic.

Various strains have been carried from Asia to Alaska over millennia, according to scientists. And the remoteness of Indigenous communities meant isolation from medical services, making early diagnosis difficult in the past, allowing infections to linger and be passed down through generations, according to scientists.

In Alaska, children infected with the virus early in life had a high likelihood of winding up with chronic infections that caused serious complications later, such as liver failure. The worst cases resulted in cancer, and even death.

For McMahon, now in his 80s, treating cancer-stricken children in the Yukon-Kuskokwim region, where he worked in the 1970s, was harrowing.

One of his patients was a 17-year-old high school valedictorian. A few months earlier, she started having abdominal pains, but she ignored them.

“She was really busy with school, and she’d gotten a full ride scholarship and was excited about going to the University of Alaska, representing her community,” McMahon said.

The pains turned out to be cancer, caused by a hepatitis B infection that she had not known she had. Too sick to be flown home, she died in the Bethel hospital.

“It was horrible,” McMahon said.

Another patient was an 11-year-old boy, also diagnosed after he complained of similar abdominal pain. McMahon visited him at home, where the boy was “in horrible pain” and yellow from jaundice.

“He was just crying. He said, ‘I know I’m going to die. Just help me with my pain,’” McMahon said.

“My wife was with me. She was a public health nurse. She was in tears. The community health aide practitioner was in tears. I was fighting my tears and pulling everything I could out of my bag to try to help this patient sedate. It was just something I’ll never forget. Never,” McMahon said.

He has relayed these and other experiences to the vaccine advisory committee in hopes of persuading members to keep the infant recommendations in place.

“I said, ‘Do you want to be responsible for children getting liver cancer because of this decision?’” McMahon said. “So I’m probably not very popular right now.”

Alaska was one of the first places in the world where the hepatitis B vaccine was used as soon as it became available in 1981.

The pilot vaccination project was at the insistence of Alaska Native organizations, along with the state government and the Alaska congressional delegation. Under that pilot program, according to newly published study by McMahon and other researchers from ANTHC and the CDC’s Arctic program, tribal health organizations and their partners screened 53,860 Alaska Native people for infection and gave vaccines to 43,618 Alaska Native people who tested negative, along with starting the universal newborn vaccinations.

Health officials have followed the outcomes since then, and the new study lists several achievements 40 years after universal newborn vaccination started.

Since 1995, according to the study, there have been no new symptomatic cases of hepatitis B among Alaska Natives under 20 anywhere in the state. Since 2000, no new cases of hepatitis-related liver cancer have been identified among Alaska Natives of any age in the Yukon-Kuskokwim Delta, a region where prevalence was concentrated in the past, the study said. And follow-up surveillance has revealed that childhood hepatitis B vaccinations remain effective for at least 35 years, the study said.

Successes are also reflected in the trend of acute hepatitis, the form of infection that is short-lived and can be cleared from the body.

There have been no identified cases of acute hepatitis among Alaska Native children since 1992, according to Johns Hopkins University. The rate of acute hepatitis among Alaskans of all ages and ethnicities dropped from 12.1 cases per 100,000 people to 0.9 per 100,000 in the 2002-2015 period, according to the state Department of Health’s epidemiology section.

Alaska’s rate of chronic hepatitis B — the long-term and persistent infection that can lead to serious liver problems — remains higher than the national average. As of 2020, Alaska’s rate of chronic hepatitis B was 14.2 cases per 100,000 people, nearly triple the national rate of 5 cases per 100,000 people, according to a report by the state Department of Health’s epidemiology section.

McMahon said that is partly because of the legacy of infections in the older Native population, people whose childhood predated widespread vaccination, and prevalence among foreign-born residents who come from countries without widespread vaccination.

Debate over hepatitis B risks

This year, vaccine skeptics who are members of the Advisory Committee on Immunization Practices, however, along with people who are advising the committee, have argued that the risks of hepatitis B among children are too low to justify universal infant vaccination.

One of the officials making that argument at Thursday’s committee meeting was Dr. Cynthia Nevison, a vaccine skeptic hired as a CDC consultant. She contradicted McMahon’s description of children spreading the virus through casual contact with contaminated surfaces — a process known as “horizontal transmission.”

“There’s very little evidence that horizontal transmission has ever been a significant threat to the average American child, and the risk probably has been overstated,” she said at the meeting. Also overstated, she said, are the risks of “vertical transmission,” the viral transmission between mothers and their newborns.

The committee’s new recommendation must be approved by the CDC administrator before it becomes federal policy.

McMahon said that no matter how national policy might change, Alaska Native tribal health organizations will continue administering hepatitis B vaccines to newborns.

“I know they’re not going to stop. Even if they have to pay for it. They’re so aware of this,” he said.

His fears, he said, are for low-income families who depend on free vaccinations through state programs that might lose funding and for parents who are getting conflicting messages that may lead to conclusions that the vaccine is not necessary.

“It could be a real mess,” he said.

2 Feet Of Snow Traps Drivers In Michigan

Do you think that Alaska is cold during winter? Of course it is! However, the type of cold the state is experiencing right now if unprecedented. How about having consecutive days of temperatures colder than 40 degrees below zero!

This is true for much of the Alaskan interior, particularly near Fairbanks and in between the Alaska and Brooks mountain ranges.

Over the last four days in Fairbanks, temperatures have struggled to reach 40 degrees below zero, with organizers in Fairbanks even postponing their annual New Year’s Eve fireworks show due to the extreme cold.

The temperature in the final few minutes of 2025 in Fairbanks was 43 degrees below zero.

In other words, conditions are unbearably and dangerously cold, even by local standards in Central Alaska.

In Chicken, Alaska, located near the Canadian Border, temperatures dropped as low as 62 degrees below zero! Numerous other locations in the eastern Alaskan Interior have seen temperatures between 50 and 60 degrees below zero.

On top of bringing dangerously cold minimum temperatures, this most recent cold snap has also been more prolonged than usual.

Temperatures in much of Alaska have been largely colder than usual since roughly December 5th, 2025

Some regions in eastern Alaska and the neighboring Yukon Territory in Canada have seen combined December temperatures up to 30 degrees below the climatological average.

For reference, the average December temperature in Fairbanks from 1904 to 2025 is 22 degrees below zero with much of central Alaska having similarly cold December temperatures on average. The city has seen a temperature departure of 18.5 degrees below average for December 2025, ranking as the 8th coldest December on record.

This means that much of east-central Alaska has been stuck between 40 and 50 degrees below for nearly an entire month!

While many factors affect the severity of winters in Alaska, one notable statistic is the unusually high snowfall in portions of Alaska this past December. Fairbanks saw more than double its usual snowfall for the month of December.

Juneau, Alaska’s capital, located in far-southeast Alaska, has seen nearly its entire annual snowfall in December alone, at over 80 inches.

Snowfall promotes cold temperatures by reflecting light from the sun back to space. In Alaska, there is already very little sunlight during the winter due to its positioning on and near the Arctic Circle.

What little sunlight snow-covered portions of Alaska have seen has been quickly reflected back to space by the unusually heavy snowpack.

In Central Alaska, located between the Alaska and Brooks ranges, the heavy snowpack, lack of sunlight, and lack of transport of air from warmer locations have led to the development of an arctic high pressure system, leading to stable conditions and light winds. These conditions cause the land to rapidly lose heat, becoming even colder. With this arctic high pressure is in place, central Alaska has remained cold. However, a slight breakdown in the strength of the high will allow temperatures to warm somewhat (see forecast for next 3 days below).

Fortunately, this pattern will break down as we approach mid-January. A more active storm track from the Pacific is poised to bring wetter and warmer conditions to portions of Alaska, especially towards the middle to second half of the month. While this wetter pattern means snow for most, temperatures will improve, being far more bearable than the current temperatures in the 40 to 50 degree below zero range.

Alaska’s delegation responds to situation in Venezuela


ANCHORAGE, Alaska (KTUU) – Officials say Venezuela’s president, Nicolás Maduro, and his wife are in New York Saturday night after they were captured in a U.S. military operation that came amid strikes in the country’s capital.

Alaska’s delegation has responded to the situation.

Senator Dan Sullivan commented on the situation saying, “In the aftermath of last night’s remarkable operation, America and the world are safer.”

He continued, saying in-part, “Maduro was an illegitimate, indicted dictator who has been leading a vicious, violent narco-terrorist enterprise in our Hemisphere that was responsible for the deaths of tens of thousands of Americans. He will now face American justice. The interim Venezuelan government must now decide that it is in their country’s and people’s interest to cooperate with the United States and reject Maduro’s legacy of violence and narco-terrorism.”

Senator Lisa Murkowski said the U.S. does not recognize Maduro as the legitimate leader of Venezuela.

She said in-part, “While I am hopeful that this morning’s actions have made the world a safer place, the manner in which the United States conducts military operations, as well as the authority under which these operations take place, is important. When the Senate returns to Washington next week, Congress has been informed that we will receive additional briefings from the administration on the scope, objectives, and legal basis for these operations.”

Representative Nick Begich posted his statement on Facebook. He called the situation a “lawful arrest” and said it was “a powerful and flawless execution of American power and capability.”

Begich continued, saying in-part, “Stability and accountability in the Western Hemisphere are core U.S. national interests. For far too long, criminal networks operating in our own hemisphere have exploited weak governance and corruption. The result has been poisoned streets, overwhelmed borders, and countless American lives lost to fentanyl and other illicit drugs.”

Opinion: Before Alaska becomes an AI data farm, be sure to read the fine print

Opinion: Before Alaska becomes an AI data farm, be sure to read the fine print

Artificial intelligence is driving a revolution in the economy and culture of the United States and other countries. Alaska is being pitched as the next frontier for one of the most energy-intensive industries: data centers, with their primary purpose of advancing AI, socially disruptive to a degree as yet unknown.

Gov. Mike Dunleavy, the state’s biggest promoter, has invited more than a dozen high-tech firms, including affiliates of Microsoft, Facebook and Amazon, to establish “data farms” in Alaska. He has personally toured executives around potential sites in the Anchorage and Fairbanks areas. The Alaska Legislature has been a bit more circumspect, though its House Concurrent Resolution 3 (HCR 3) states that “the development and use of artificial intelligence and the establishment of data centers in the state could stimulate economic growth, create job opportunities and position the state as a leader in technological innovation.” True, however, the resolution makes no mention of drawbacks stemming from data center development.

The Northern Alaska Environmental Center (NAEC), based in Fairbanks, is examining the known and potential benefits, costs and risks of data center growth in the state. It urges a well-informed, unhurried, transparent and cautious approach.

First, though, what are data centers? They are facilities that house the servers, storage, networking and other computing infrastructure needed to support AI and other digital services, along with their associated electrical and cooling infrastructure.

Generally speaking, there are two categories of data centers. One is the massive hyperscale facility, typically operating at multi-megawatt scale and designed to scale much higher. An example is the proposed Far North Digital (FND) Prudhoe Bay Data Center. It would start with a capacity of 120 megawatts with “significant expansion potential.” Natural gas would power it.

The other kind is the micro or microgrid data center. A good example is Cordova’s Greensparc Corp/Cordova Electric Cooperative 150-kilowatt facility. It is powered by 100% renewable energy from the nearby hydroelectric plant. We concur with the University of Alaska Fairbanks’ Alaska Center for Energy and Power (ACEP) analysis that contends that such smaller and sustainable data centers, sometimes integrated into existing microgrids, are more feasible for Alaska, particularly in underserved or remote communities.

The main problem with data centers is their high to huge energy demands, especially hyperscale ones that can consume as much electricity as 100,000 homes. Cooling can account for about 40% of a facility’s energy use, though it varies. While Alaska’s cold climate is an environmental advantage, reducing the need for energy-intensive mechanical cooling systems, cooling still requires a lot of water. The NAEC advocates that any new data centers be required to minimize use and thermal pollution of waters and reuse waste heat for local heating.

The Railbelt grid already faces constraints and expensive upgrade needs. The NAEC believes that if new data centers are developed, regulatory safeguards must be in place to ensure they do not exacerbate grid shortages and raise household electricity costs.

Most electricity powering data centers still comes from fossil fuels, even as operators sign renewable contracts and add clean generation. Building fossil fuel-powered data centers would lock in high-emissions infrastructure for decades, contradicting global decarbonization efforts. NAEC suggests that any new data center be required to build or contract for an equivalent amount of clean energy generation (wind, solar, hydro or geothermal) to match its consumption.

There are many other concerns that need to be addressed when considering data centers and AI development. One is the problem of electronic waste, or e-waste. Needed upgrades to data centers result in e-waste, which contains hazardous materials. Given Alaska’s remote potential sites and limited recycling infrastructure, the cost of appropriately dealing with e-waste should be factored into data center decisions.

In their haste to recruit data centers, several states have granted substantial tax abatements and subsidies, often with limited public benefit. Alaska must learn from the mistakes made elsewhere. Before considering approval of any new data centers, legislation should be in place that ensures that the corporations that will profit do not get discounted power rates or tax breaks and pass additional costs to ratepayers, including costs for needed upgrades.

Yes, data centers provide some much-needed diversification to Alaska’s economy, but not much. They are highly capital intensive and employ many in the construction phase, but few for operation. Companies should be required to train and hire local residents to the degree practical.

Then there is the profound but scarcely recognized issue that transcends energy, economics and the environment. Data centers expand the compute available for increasingly capable AI systems. Some researchers and industry leaders argue this could accelerate progress toward AI that matches or exceeds human capabilities, along with new risks. Ultimately, the greatest cost of data centers and AI may be the changes wrought to our humanity and society, for which we are woefully unprepared.
