New vaccine approach targets broad protection against arenavirus infections

Scientists at La Jolla Institute for Immunology (LJI) have discovered that combining key vaccine ingredients could give the body the tools it needs to fight the entire family of arenaviruses with a single vaccine.

Wastewater tracking catches hospital fungus before patients show symptoms

A new UNLV-led wastewater surveillance study brings scientists one step closer in the global race to detect and deter skyrocketing cases of a potentially deadly drug-resistant fungus that puts hospital patients at risk of serious blood, heart, or brain infections.

Adjuvanted and high-dose flu vaccines protect older adults equally well

In a large study of 429,595 adults aged 65 years or older, adjuvanted and high-dose influenza vaccines showed no significant difference in protection against PCR-confirmed influenza. The findings support current recommendations that both enhanced vaccines are reasonable options for older adults, while second-season results may further refine the evidence.

New mRNA vaccine strategy dramatically amplifies cancer-fighting T cells

Engineers from the University of Houston, MIT and Harvard have developed a new mRNA-based strategy that dramatically amplifies the T-cell response to vaccines - an advance that could lead to far more powerful cancer vaccines and stronger protection against infectious diseases.

Climate change drives emerging vector-borne diseases in Canada

Climate change is affecting the local ecology in Canada, contributing to emerging tick- and mosquito-borne diseases and infections in humans, argue authors of a commentary published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.260668.

Bundibugyo virus outbreak triggers international public health emergency declaration

Pursuant to paragraph 2 of Article 12 - Determination of a public health emergency of international concern, including a pandemic emergency of the International Health Regulations (2005) (IHR), the Director-General of the World Health Organization (WHO), after having consulted the States Parties where the event is known to be currently occurring, is hereby determining that the Ebola disease caused by Bundibugyo virus in the Democratic Republic of the Congo and Uganda constitutes a public health emergency of international concern (PHEIC), but does not meet the criteria of pandemic emergency, as defined in the IHR.

Health experts outline symptoms and risks of shipboard hantavirus

It's one of the cruisegoer's biggest fears: a contagious disease outbreak at sea.

Asymptomatic transmission plays a prominent role in mpox infection patterns

A Kaiser Permanente study of nearly 8,000 men shows that in mid- to late 2024, mpox was far more common among men who have sex with men than previously thought. Individuals without symptoms accounted for most infections and likely played a prominent role in transmission, contrary to prior assumptions that people had to be symptomatic to spread the disease.

Turning the flu virus into a powerful tool to fight cancer

A recent Views & Comments article published in Engineering highlights advances in repurposing influenza viruses as flexible therapeutic platforms for infectious diseases and cancer, driven by progress in reverse genetics and viral vector engineering.

New mRNA adjuvant dramatically boosts T-cell vaccine responses in mice

MIT engineers have developed a new way to amplify the T-cell response to mRNA vaccines - an advance that could lead to much more powerful cancer vaccines and stronger protection against infectious diseases.

New malaria vaccine offers long-lasting protection without refrigeration

Malaria is a deadly disease killing more than half a million people every year, but a new vaccine is showing promise as it not only offers long-lasting strong protection but also inhibits transmission of malaria by mosquitos.

A century of safety: Aluminium vaccine adjuvants do not raise serious long-term health risks

A BMJ systematic review of 59 human studies found no evidence supporting causal links between aluminum-adjuvanted vaccines and serious or long-term outcomes such as autism spectrum disorder, asthma, autoimmune conditions, or other chronic illnesses. The most consistent adverse events were uncommon, local, self-limited persistent nodules or granulomas, likely reflecting delayed-type hypersensitivity.

Rockefeller scientists reveal how HIV strains escape broadly neutralizing antibodies

Broadly neutralizing antibodies (bNAbs) are among the most promising new treatments for HIV, offering the potential to forego traditional daily dose of antiretroviral drugs.

Andes hantavirus outbreak highlights global spillover and transmission risks

A Virginia Tech disease ecologist said the outbreak of Andes hantavirus aboard the international MV Hondius cruise ship underscores how little scientists still know about the viruses circulating silently in wild rodent populations before they spill into humans.
