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.

Recent years have witnessed an increasing use of coordinated accounts on social media, operated by misinformation campaigns to influence public opinion and manipulate social outcomes. Consequently, there is an urgent need to develop an effective methodology for coordinated group detection to combat the misinformation on social media. However, the sparsity of account activities on social media limits the performance of existing deep learning based coordination detectors as they can not exploit useful prior knowledge. Instead, the detectors incorporated with prior knowledge suffer from limited expressive power and poor performance. Therefore, in this paper we propose a coordination detection framework incorporating neural temporal point process with prior knowledge such as temporal logic or pre-defined filtering functions. Specifically, when modeling the observed data from social media with neural temporal point process, we jointly learn a Gibbs distribution of group assignment based on how consistent an assignment is to (1) the account embedding space and (2) the prior knowledge.

The new paradigm of fine-tuning-as-a-service introduces a new attack surface for Large Language Models (LLMs): a few harmful data uploaded by users can easily trick the fine-tuning to produce an alignment-broken model. We conduct an empirical analysis and uncovera \textit{harmful embedding drift} phenomenon, showing a probable cause of the alignment-broken effect. Inspired by our findings, we propose Vaccine, a perturbation-aware alignment technique to mitigate the security risk of users fine-tuning. The core idea of Vaccine is to produce invariant hidden embeddings by progressively adding crafted perturbation to them in the alignment phase. This enables the embeddings to withstand harmful perturbation from un-sanitized user data in the fine-tuning phase. Our results on open source mainstream LLMs (e.g., Llama2, Opt, Vicuna) demonstrate that Vaccine can boost the robustness of alignment against harmful prompts induced embedding drift while reserving reasoning ability towards benign prompts.

Parents in north London have been told their children could be excluded from school if they are not fully vaccinated against measles amid an outbreak of the highly-contagious disease. Unvaccinated pupils identified as close contacts of people with measles could be excluded for 21 days in accordance with national guidelines, Enfield Council said in a letter to all parents in the borough in late January. At least 34 children have contracted measles in Enfield so far this year, the UK Health Security Agency (UKHSA) has said, and a number sent to hospital. A local health chief meanwhile told the BBC: We are worried because actually, this is a significantly increased number than what we're used to. Asking unvaccinated, close contacts of measles cases to stay off school is fairly standard practice when there are local outbreaks.

How a gift for shooting the shit turned into an online empire--and a political force. Trust in American mass media has plummeted; more than three thousand newspapers have disappeared in the past two decades, and many people get their news from social platforms. In this chaotic media multiverse, Rogan has emerged as a figure of singular influence. For a long time, I stayed up through the night listening to tall-tale tellers, U.F.O. I could not get enough of it. I was a fairly ordinary kid, Jersey-born, but the house I lived in was shadowed by illness. My mother had been diagnosed with a debilitating neurological disease when she was in her early thirties. Every year, she got worse. During the day, I wanted nothing more than to please my mother, do well in school, lighten her load. At night, I wanted only to climb into the shelter of my bed and turn on the radio. I was hungry for elsewhere, for other lives--for what was being said down the street, over the bridge, beyond the horizon. On clear nights, the signal was strong. You could hear the country expressing itself incessantly: everyone was phoning in, suggesting three-way trades, bitching about the mayor, speaking in tongues, raging, joking, climbing out on a ledge and threatening to jump. When I wanted a few hours of sleep before school, I tuned in to a ballgame on the West Coast. The staticky murmur of the crowd in Anaheim or Chavez Ravine was a sure slide to oblivion. Mostly, though, I wanted nothing to do with sleep. Mostly, I was tuned in, midnight to five-thirty, to "The Long John Nebel Show."

Among those Robert F. Kennedy Jr. recently named to a federal autism committee are people who tout dangerous treatments and say vaccine manufacturers are "poisoning children." US health secretary Robert F. Kennedy Jr. has filled an autism committee with friends, associates, and former colleagues who believe that autism is caused by vaccines. Autism advocates are now worried the group could pave the way for dangerous pseudoscientific treatments going mainstream. Last week, Kennedy announced an entirely new lineup for the Interagency Autism Coordinating Committee (IACC), a group that recommends what types of autism research the government should fund and provides guidance on the services the autism community requires. The group is typically composed of experts in the area of autism research, along with policy experts and autistic people advocating for their own community.

Experts worry it will be used to further Robert F. Kennedy Jr.'s anti-vaccine agenda. Get your news from a source that's not owned and controlled by oligarchs. The US Department of Health and Human Services (HHS) is developing a generative artificial intelligence tool to find patterns across data reported to a national vaccine monitoring database and to generate hypotheses on the negative effects of vaccines, according to an inventory released last week of all use cases the agency had for AI in 2025. The tool has not yet been deployed, according to the HHS document, and an AI inventory report from the previous year shows that it has been in development since late 2023. But experts worry that the predictions it generates could be used by HHS secretary Robert F. Kennedy Jr. to further his anti-vaccine agenda.

A long-standing vaccine critic, Kenedy has upended the childhood vaccination schedule in his year in office, removing several shots from a list of recommended immunizations for all children, including those for Covid-19, influenza, hepatitis A and B, meningococcal disease, rotavirus, and respiratory syncytial virus, or RSV.
