High street pharmacies across England are now offering a free meningitis B vaccine for many young people. It comes after concerns over the UK's largest and fastest growing outbreak that happened in Kent earlier this year. So who needs the vaccine and what's in it? What's the vaccine and is it safe? The vaccine offers protection against a dangerous strain of meningitits called meningitis B (MenB) that caused the outbreak in Kent. The vaccine does not contain any live bacteria and cannot cause meningitis.

A man gets his Covid and flu vaccine shot at Boston city hall on 7 January 2026. A man gets his Covid and flu vaccine shot at Boston city hall on 7 January 2026. Adults in the US who frequently seek out health advice from artificial intelligence chatbots are more likely to believe myths about vaccines, according to a poll released on Tuesday by health research firm KFF. The survey, which was conducted in May and polled a representative sample of 2,480 US adults, found that use of AI tools and chatbots correlated with belief in falsehoods such as vaccines causing autism or that the measles vaccine poses more danger than the corresponding virus. The connection remained while controlling for factors such as age, race, education and political partisanship.

Years after initial tests, researchers are now racing to see if a vaccine developed in 2011 can help fight the current Bundibugyo outbreak in Congo. Fever was the first symptom to grip the crab-eating macaques in their high-containment laboratory on an island off Texas after being infected with the newly discovered Bundibugyo strain of ebola . Then came the weight loss, the rectal bleeding and nosebleeds, while scientists in space suits drew blood to see how the monkeys' immune systems struggled to fight the aggressive virus. But the three monkeys that had received a newly developed vaccine to protect against the understudied strain showed no symptoms of the disease, which eventually killed two-thirds of their unvaccinated companions. It was 2011, and virologist Thomas Geisbert's work developing the vaccine was done.

The DeceptionBench is designed as a research benchmark to systematically study deception behaviors in LLMs, fostering a deeper understanding of their decision-making processes in real-world scenarios. Our primary intent is to provide a standardized, transparent tool for the research community to evaluate and improve LLMs' ethical alignment, not to enable or encourage deceptive practices. To prevent potential misuse by malicious actors, we commit to publicly releasing all evaluation data under an open license. This transparency ensures that DeceptionBench's methodology and outcomes are subject to scrutiny, replication, and improvement by the research community, reducing the risk of hidden exploitation. By prioritizing openness, we aim to advance responsible AI development while safeguarding against misuse in harmful contexts. The field of Large Language Models (LLMs) has undergone remarkable evolution in recent years, reshaping the landscape of natural language processing.

Despite the remarkable advances of Large Language Models (LLMs) across diverse cognitive tasks, the rapid enhancement of these capabilities also introduces emergent deception behaviors that may induce severe risks in high-stakes deployments. More critically, the characterization of deception across realistic real-world scenarios remains underexplored. To bridge this gap, we establish DeceptionBench, the first benchmark that systematically evaluates how deceptive tendencies manifest across different societal domains, what their intrinsic behavioral patterns are, and how extrinsic factors affect them. Specifically, on the static count, the benchmark encompasses 150 meticulously designed scenarios in five domains, i.e., Economy, Healthcare, Education, Social Interaction, and Entertainment, with over 1,000 samples, providing sufficient empirical foundations for deception analysis. On the intrinsic dimension, we explore whether models exhibit self-interested egoistic tendencies or sycophantic behaviors that prioritize user appeasement. On the extrinsic dimension, we investigate how contextual factors modulate deceptive outputs under neutral conditions, reward-based incentivization, and coercive pressures. Moreover, we incorporate sustained multi-turn interaction loops to construct a more realistic simulation of real-world feedback dynamics. Extensive experiments across LLMs and Large Reasoning Models (LRMs) reveal critical vulnerabilities, particularly amplified deception under reinforcement dynamics, demonstrating that current models lack robust resistance to manipulative contextual cues and the urgent need for advanced safeguards against various deception behaviors.

An AI-designed universal vaccine targeting a broad range of coronaviruses passed its first clinical trial, proving safe and triggering an immune response in 39 healthy volunteers.

The work of Peter Aaby and Christine Stabell Benn has long been controversial. Until Robert F. Kennedy Jr. became US health policy chief, most vaccine scientists tended to ignore it. In 1996, Guinea-Bissau seemed like an ideal research post for budding pediatrician Lone Graff Stensballe. Her supervisor, a fellow Dane named Peter Aaby, had spent nearly two decades collecting data on 100,000 people living in the mud brick homes of the West African country's capital. Aaby and his partner, Christine Stabell Benn, believed that the years of research in the impoverished country had yielded a major discovery about vaccines--and what they described as "non-specific effects": The measles and tuberculosis vaccines, which were derived from live, weakened viruses and bacteria, they said, boosted child survival beyond protecting against those particular pathogens. But, the scientists said, shots made from deactivated whole germs, or pieces of them, such as the diphtheria-tetanus-pertussis (DTP) shot, caused more deaths--especially in little girls--than getting no vaccine at all.

From claims of an Israeli false flag to efforts to sell ivermectin, influencers and grifters are using lessons learned from Covid-19 to push their baseless conspiracy theories. Conspiracy theorists, wellness influencers, and grifters have already started promoting wild claims about the hantavirus outbreak that began aboard the MV, a cruise ship on the Atlantic. Some conspiracy theorists compared the outbreak to the Covid-19 pandemic, claiming it was another effort to control the global population, while others pushed a false narrative that the Covid-19 vaccine caused hantavirus. Many others promoted ivermectin as a treatment, using the incident as a way to sell emergency medical kits featuring the antiparasitic drug typically used as a horse dewormer. In more recent days, many of these same people spreading conspiracy theories have promoted the baseless and antisemitic claims that the entire incident is a false flag orchestrated by Israel.

Since 2023, Moderna and Korea University have been developing a new mRNA vaccine for hantavirus. The work has been promising so far, but a finished product isn't likely coming any time soon. US-based pharmaceutical company Moderna confirmed that it has been working on the development of hantavirus vaccines in collaboration with the Vaccine Innovation Center of Korea University College of Medicine (VIC-K). This comes after an outbreak of hantavirus occurred on a Dutch cruise ship that sailed from Argentina and disembarked its passengers and crew in the Canary Islands on May 10. At least three people aboard the MV died, and several cases were reported as serious.
