CDC Investigates Flu-Linked Brain Complications in Children

CDC Investigates Flu-Linked Brain Complications in Children \ Newslooks \ Washington DC \ Mary Sidiqi \ Evening Edition \ With this year’s flu season the worst in 15 years, the CDC is investigating whether it contributed to an increase in rare but severe brain complications in children. At least nine pediatric flu deaths involved neurological conditions, such as encephalopathy and encephalitis, prompting a nationwide alert to doctors. Despite concerns, flu vaccines have shown strong protection against hospitalization, reducing risks by 64% to 78% in children. Meanwhile, uncertainty looms over next year’s flu shot production after the Trump administration abruptly canceled a key FDA advisory meeting.

Flu Season Health Concerns: Quick Looks

• Flu Deaths Rise: An estimated 19,000 people, including 86 children, have died from the flu this season.
• Rare Brain Complications: At least nine pediatric flu deaths involved severe neurological conditions, raising CDC concerns.
• Statewide Investigations: The CDC has asked state health departments to help track additional cases.
• Flu Vaccine Effectiveness: This year’s shots reduced hospitalization risk by 64%-78% in kids, 41%-55% in adults.
• Parental Alert: Doctors advise parents to watch for flu-related seizures, hallucinations, or labored breathing.
• No Routine Tracking: The U.S. does not systematically monitor flu-related neurological complications, making trends unclear.
• FDA Meeting Canceled: A March 13 meeting to decide next year’s flu vaccine composition was abruptly scrapped.
• Government Secrecy Concerns: Experts worry about lack of transparency in future flu vaccine decision-making.

Deep Look

Worst Flu Season in Over a Decade Raises Alarms

With this year’s flu season reaching record levels, the Centers for Disease Control and Prevention (CDC) is now investigating whether it has triggered an increase in life-threatening brain complications in children.

At least 86 children have died from the flu this season, and on Thursday, the CDC reported that nine of those deaths involved severe neurological conditions, such as:

• Influenza-associated encephalopathy or encephalitis – inflammation of the brain caused by viral infection.
• Acute necrotizing encephalopathy (ANE) – a rare and more severe subtype, linked to long-term brain damage or death.

The CDC has asked state health departments to investigate additional cases, fearing the actual number may be higher than reported.

While flu-related brain complications are rare, past outbreaks have shown certain influenza strains may increase neurological risks. However, without routine tracking, experts lack the data needed to determine whether this season represents an actual surge in cases.

Flu Vaccine Strongly Reduces Risk of Hospitalization

Despite concerns, there is positive news: This year’s flu vaccine has provided strong protection against severe illness.

According to the CDC’s preliminary data:

• Children who received the flu shot were 64% to 78% less likely to be hospitalized.
• Adults saw a 41% to 55% reduction in hospitalization risk.

Experts stress that even though the flu shot does not completely prevent infection, its primary benefit is keeping patients out of the hospital and alive.

“The flu vaccine’s main role is to keep you out of the hospital and to keep you alive,” said Dr. William Schaffner, a vaccine expert at Vanderbilt University.

Flu-Related Brain Complications: What Parents Need to Know

Earlier this month, the CDC issued an alert to doctors across the country, urging them to watch for flu patients—especially children—who exhibit unusual symptoms, including:

• Seizures
• Hallucinations
• Confusion or disorientation
• Severe weakness or paralysis
• Difficulty breathing or prolonged fever

Parents should seek immediate medical attention if their child experiences any of these symptoms while battling the flu.

Dr. Sean O’Leary, vice chair of the American Academy of Pediatrics, reassured families that these complications remain rare but emphasized the importance of early detection.

“Anytime a child has concerning symptoms while sick with the flu, they should be evaluated by a doctor,” he said.

California Reports More Cases, But Nationwide Tracking Is Limited

Tracking flu-related brain complications is inconsistent across the U.S., making it difficult to confirm an increase in cases.

However, Dr. Keith Van Haren of Stanford Medicine Children’s Health recently reported at least 15 cases of severe flu-related encephalopathy among children in different states. He noted that more potential cases are under review, though he did not specify how many resulted in death.

Without a nationwide surveillance system, it remains unclear whether this season’s cases reflect a genuine surge or expected numbers in a severe flu year.

Controversy Over Next Year’s Flu Vaccine: Trump Administration Cancels Key Meeting

As health officials scramble to respond to this year’s flu crisis, uncertainty clouds preparations for next winter’s flu vaccine.

The Food and Drug Administration (FDA) had planned a March 13 meeting where expert scientists would select the flu strains to include in next year’s vaccine.

However, the Trump administration abruptly canceled the meeting, leaving public health officials and vaccine makers in the dark.

• This raises concerns about lack of transparency in government vaccine decisions.
• The FDA has not explained how it will select next year’s flu strains without the usual advisory process.
• The decision follows a trend of Trump’s administration sidelining independent scientific advisors in health policy.

“We have historically worked really hard to get transparency around all of these vaccine discussions,” said Dr. O’Leary, stressing that public trust in vaccines relies on an open decision-making process.

Despite the canceled meeting, the Department of Health and Human Services (HHS) assured that updated vaccines will be available for the 2025-2026 flu season.

Andrew Nixon, HHS communications director, stated:
“The FDA will make public its recommendations to manufacturers in time for updated vaccines to be available.”

However, without scientific advisors publicly reviewing the data, some experts worry that political interference could influence vaccine formulation decisions.

Looking Ahead: What This Means for Public Health

With flu season still in full swing, experts emphasize that it’s not too late to get vaccinated.

“If you haven’t gotten your flu shot yet, get it because we’re still seeing high flu circulation in most of the country,” Dr. O’Leary advised.

Meanwhile, health officials face critical decisions in the coming months:

1. Tracking flu-related brain complications – Will the CDC create a better surveillance system to detect patterns?
2. Preparing for next winter – How will the FDA choose next year’s flu vaccine formula without expert input?
3. Rebuilding public trust – Can the government ensure transparency in vaccine decision-making amid political disruptions?

For now, scientists continue working to understand this year’s flu season, but the cancellation of a key advisory meeting raises new concerns about the future of flu prevention in the U.S.
