Corner Therapeutics says its "hyperactivator" adjuvant technology can offer protection against all virus strains.

Results from a Danish trial of more than 330,000 adults 65 years or older found high- and standard-dose influenza vaccines had similar effectiveness against influenza or pneumonia-related hospitalizations.

This comes after the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices (ACIP) made the recommendation to remove the vaccine preservative.

Vaccine candidate demonstrates 26.6% higher relative efficacy in adults 50 and older, with strong protection across flu strains.

Phase 3 results show immune response and tolerability in adults 65 and older, following phase 2 findings.

The ongoing H5N1 avian flu outbreak has severely impacted U.S. poultry and dairy industries, prompting a $1 billion USDA response strategy that includes biosecurity, vaccination research, and innovation funding. With growing concern over viral mutations affecting humans and livestock, rapid, field-based diagnostic tools offer critical support in accelerating detection and containment efforts.

Despite the funding being terminated, the company said data from its phase 1/2 study of its investigational vaccine, mRNA-1018, demonstrated positive interim results.

Michigan dairy worker's infection is linked to widespread H5N1 outbreaks, as new findings suggest increased transmission risk and moderate disease in mammals.

Despite political restructuring and funding cuts, the NIH’s Generation Gold Standard vaccine platform offers a promising solution for pandemic preparedness and global health resilience.

This case represents the second reported human infection with avian influenza A(H5) in Mexico, and the first confirmed case of influenza A(H5N1) in the country. The patient was a child who died from respiratory complications.

Jeff Fischer, MBA, discusses promising preclinical data on a cross-species, cross-strain influenza candidate with pandemic potential at the 2025 Congress of the European Society of
Clinical Microbiology and Infectious Diseases.

Key updates from the Centers for Disease Control and Prevention on influenza activity, hospitalizations, pediatric deaths, and current trends across the United States.

The most recent CDC report accounts for 33 million flu illnesses, 430,000 hospitalizations, and 19,000 deaths this flu season, with Influenza A(H1N1) and A(H3N2) as the primary strains.

The CDC tracks rising human infections linked to poultry and dairy exposure, while the USDA steps up with a comprehensive strategy to combat HPAI and stabilize egg prices.

Two cats became severely ill, and both owners declined to be tested.

A state official says the woman is hospitalized in another state, and had preexisting health conditions that can make people more vulnerable to illness.

The affected person had a mild case and is recovering.

The Louisiana Department of Health announced the news late yesterday, and it is the first death in the US associated with the H5N1 virus.

Older males who had these infections had a statistically significant higher risk for physical and cognitive impairments.

The federal health agency stresses the importance of finding the balance between vigilance and enjoying normal activities.

New approach targets multiple strains, promising broad protection against human, avian, and swine influenza viruses.

Veterinary and public health officials share the important roles of surveillance and prevention strategies, insights on the virus's transmission pathways, historical context, the One Health approach, and highlights effective precautionary measures to mitigate H5N1 risks.
