In-Depth Report

COVID-19 Vaccines and U.S. Public Health Upheaval

Targeted Fall Boosters, But Access Tightened: U.S. health authorities approved new monovalent COVID-19 vaccines (by Pfizer–BioNTech, Moderna, and Novavax) updated for the 2025–26 season reuters.com. Unlike prior booster rollouts, the FDA restricted under-65 eligibility to those with risk factors, aligning with guidance from HHS Secretary Robert F. Kennedy Jr., a longtime vaccine skeptic reuters.com. The change marks a sharp departure from broad eligibility in previous years. Officials and experts voiced concern that narrowing access could sow confusion over insurance coverage and leave many younger adults unprotected reuters.com reuters.com. Notably, the FDA also rescinded emergency authorization for Pfizer’s vaccine in children under 5, effectively pausing toddler immunizations reuters.com. Medical societies pushed back – the Infectious Diseases Society of America announced it is working with other groups on independent COVID vaccine guidelines, expected in September reuters.com. The American Academy of Pediatrics even went against federal policy, recommending that all young children get vaccinated for COVID-19 reuters.com.

“Making America Healthy Again” or Undermining Science?: The narrower vaccine rollout comes amid turmoil at the CDC. CDC Director Dr. Susan Monarez was fired on Aug. 27, just weeks into the job, after clashing with HHS Secretary Robert F. Kennedy Jr. over his sweeping vaccine policy changes reuters.com reuters.com. Kennedy – a controversial figure due to anti-vaccine activism – had already withdrawn federal COVID shot recommendations for healthy kids and pregnant women in May and ousted the CDC’s expert vaccine advisory panel in June, installing his own picks reuters.com reuters.com. Monarez’s ouster and the exodus of four senior CDC scientists underscore the internal revolt. In resignation letters seen by Reuters, officials decried “the overstating of risks and the rise of misinformation [that] have cost lives” reuters.com, citing record U.S. measles outbreaks and even violent threats to the agency. The White House defended Monarez’s firing, saying she was “not aligned with the President’s agenda of Making America Healthy Again” reuters.com, while Monarez (through her attorneys) insisted she would “not resign” and stood by science reuters.com. The shakeup raises fears that political interference is sidelining evidence-based public health. As one former CDC official put it, public health is being “weaponized,” with budget cuts and leadership purges threatening the agency’s effectiveness reuters.com reuters.com.

Drug Approvals and Regulatory Developments

Updated COVID Shots Roll Out Globally: Despite U.S. limits, the fall COVID-19 vaccine updates are underway internationally. Pfizer and BioNTech announced FDA approval of their new booster targeting the Omicron JN.1 lineage subvariant LP.8.1 pfizer.com pfizer.com. The 2025–26 formula is formulated to better match currently circulating strains and will ship immediately, aiming for pharmacies and clinics in the coming days pfizer.com pfizer.com. Health officials hope the strain-specific booster will rejuvenate immunity ahead of winter, especially for seniors and high-risk groups. So far, over 5 billion doses of Pfizer–BioNTech’s COVID vaccine have been distributed globally, and real-world evidence continues to support its safety profile pfizer.com. Other countries are also acting: Britain and EU regulators are reviewing similar variant-tailored shots to deploy this fall.

U.K. Debuts a Novel Antibiotic: In a rare win against antimicrobial resistance, the U.K. approved Blujepa (gepotidacin), a new antibiotic pill from GSK, to treat uncomplicated UTIs in females 12 and up reuters.com reuters.com. It’s the first antibiotic in nearly 30 years with a totally new mechanism: Blujepa blocks two bacterial enzymes needed for DNA replication, enabling it to kill even drug-resistant strains of E. coli reuters.com reuters.com. The MHRA noted Blujepa’s novel approach and confirmed it’s effective against many infections that standard antibiotics no longer clear. The drug is taken as two pills twice daily for 5 days reuters.com. GSK welcomed the decision and said it will work with NICE on access for National Health Service patients reuters.com. The U.S. FDA had approved gepotidacin earlier in March, and this month accepted a priority review for using it against gonorrhea – another area desperate for new antibiotics reuters.com reuters.com. GSK projects robust demand: it expects Blujepa and a couple other pipeline meds to eventually top £2 billion in annual sales reuters.com, as the company races to offset revenue lost to patent expirations. Public health advocates hail Blujepa as a “game-changer” in the fight against superbugs, given the dire shortage of novel antibiotics over past decades.

Hope for a Pediatric Brain Cancer: Jazz Pharmaceuticals’ Modeyso (dordaviprone) just earned FDA accelerated approval, making headlines as the first-ever approved therapy for diffuse midline glioma with the H3 K27M mutation targetedonc.com targetedonc.com. This aggressive brain tumor (often in children and young adults) has long been a death sentence – historically there were no effective drugs, only palliative radiation. In a small pooled study of 50 patients, Modeyso showed a 22% overall response rate (tumor shrinkage) with responses lasting ~10 months on average targetedonc.com targetedonc.com. While modest, any response is a breakthrough for this cancer, which typically kills patients within a year (median survival is under 9 months for H3 K27M cases) targetedonc.com. Dordaviprone, a targeted oral therapy, was also well-tolerated with mainly mild side effects targetedonc.com targetedonc.com. “This is a significant milestone,” said Dr. Patrick Wen of Dana-Farber Cancer Institute, noting it fills a dire gap for a “challenging and aggressive tumor” that surgeons cannot fully remove targetedonc.com targetedonc.com. The approval is conditional on confirmatory trials – a Phase 3 study called ACTION is underway to verify benefits in newly diagnosed patients targetedonc.com targetedonc.com. Still, for families facing diffuse midline glioma, Modeyso’s approval offers a new ray of hope after decades of research dead-ends.

FDA Setbacks and Safety Actions: In other regulatory news, Amylyx Pharmaceuticals announced it will halt development of AMX0035 for a rare neurodegenerative disease after a Phase 2 trial failure reuters.com reuters.com. The experimental drug (a combo of sodium phenylbutyrate and taurursodiol) showed no benefit for progressive supranuclear palsy (PSP), a fatal brain disorder with no approved treatments reuters.com reuters.com. “We are disappointed in these results,” said Amylyx’s Chief Medical Officer Dr. Camille Bedrosian, adding that the company had set a “high bar” for success in PSP reuters.com. AMX0035 had earlier won approval (as Relyvrio) for ALS in 2022, but Amylyx voluntarily withdrew it in the U.S. and Canada after a larger trial failed to confirm efficacy reuters.com reuters.com. The PSP failure prompted Amylyx to stop both the mid-stage trial and an open-label extension, and scrap plans for a Phase 3 in PSP reuters.com. Meanwhile in Australia, Telix Pharmaceuticals saw its shares plunge ~19% after disclosing the FDA won’t approve its new kidney cancer diagnostic without more data reuters.com reuters.com. Telix’s injectable tracer, branded Zircaix, aims to detect clear cell renal carcinoma via PET scan. The FDA flagged that Telix’s scaled-up manufacturing process wasn’t yet proven equivalent to the one used in clinical trials reuters.com reuters.com. Telix said it will quickly provide the requested chemistry and comparability data and still hopes to launch Zircaix in the U.S., but investors reacted nervously to the delay reuters.com reuters.com. These developments underscore the high-risk, high-reward nature of drug R&D – with hard-fought victories for some novel therapies and frustrating setbacks for others.

Clinical Trial Milestones and Medical Research Advances

Oral Weight-Loss Drug Matches Injectables: The weight-loss drug boom continues, and now a pill may join the fray. Eli Lilly’s oral GLP-1 agonist, orforglipron, delivered impressive results in its latest Phase 3 trial, Attain-2. At the highest dose (36 mg daily), orforglipron patients achieved about 10.5% body weight reduction after 72 weeks, far outstripping the 2.2% loss on placebo pharmexec.com pharmexec.com. The pill also significantly lowered HbA1c (long-term blood sugar), with three-quarters of high-dose patients bringing their diabetes into remission-level control pharmexec.com. Participants on orforglipron saw improvements in blood pressure, cholesterol, and triglycerides as well pharmexec.com pharmexec.com – key cardiovascular benefits given obesity’s risks. Side effects were mainly mild-to-moderate GI upset, similar to injectable GLP-1 drugs like semaglutide. Lilly now has data from three successful Phase 3 trials and is preparing global regulatory submissions pharmexec.com pharmexec.com. Obesity specialists are enthusiastic: “These data show the potential for orforglipron to offer an efficacy, safety, and tolerability profile consistent with the injectable GLP-1 class,” said Dr. Louis Aronne of Weill Cornell, adding that an effective pill could “expand treatment options for patients who prefer oral therapies” pharmexec.com. With demand for weight-loss treatments soaring, an oral alternative to popular injections (like Ozempic and Mounjaro) could be a game-changer if approved.

At-Home Psychiatric Treatment Succeeds: BioXcel Therapeutics reported a positive late-stage trial for an at-home version of its sedative film BXCL501 (dexmedetomidine), opening the door for a new way to manage acute agitation in psychiatric patients. BXCL501, already approved as Igalmi for use under medical supervision, was tested for self-administration by patients with schizophrenia or bipolar disorder who experience agitation episodes. In the Phase 3 trial of 200+ patients, those who took the dissolvable film at home showed significantly calmed symptoms and, importantly, had fewer adverse events even with repeat dosing over 12 weeks reuters.com. The drug was well-tolerated, with no new safety issues. Early use of the film could prevent crises from escalating to ER visits or hospitalization. “Early intervention at home can prevent symptom escalation and reduce emergency room visits,” explained BioXcel CEO Vimal Mehta reuters.com. Buoyed by the data, BioXcel plans to seek FDA approval by early next year for home use of BXCL501 reuters.com. Analysts noted the result fills an unmet need – currently, there are no easy at-home treatments for acute psychiatric agitation, forcing many patients into costly urgent care. Investors, however, reacted cautiously: BioXcel’s stock actually dropped 20% after the news, which experts attributed to profit-taking after a recent rally (the stock had doubled in anticipation of results) reuters.com. In any case, if approved, BXCL501 could empower caregivers and patients to safely manage episodes in the community, a significant advance in mental health care.

Alzheimer’s Clue from Green Tea and Vitamin B3: A notable lab research breakthrough this week offers hope for brain aging and Alzheimer’s disease. Scientists found that two natural compounds – nicotinamide (a form of vitamin B₃) and EGCG (an antioxidant in green tea) – can reverse key signs of aging in brain cells independent.co.uk independent.co.uk. In neuron cultures and mouse models, a 24-hour treatment with these molecules restored levels of GTP (a vital energy-carrying molecule) in old brain cells to that seen in young cells independent.co.uk independent.co.uk. Boosting cellular energy in turn reactivated the cells’ “garbage disposal” process (autophagy) – enabling neurons to clear out toxic protein clumps like amyloid-beta, which is a hallmark of Alzheimer’s independent.co.uk independent.co.uk. Treated older neurons showed improved ability to eliminate amyloid proteins, essentially behaving more youthfully independent.co.uk independent.co.uk. “As people age, their brains show a decline in neuronal energy levels, which limits the ability to remove unwanted proteins,” explained lead author Dr. Gregory Brewer. “We found that restoring energy levels helps neurons regain this critical cleanup function.” independent.co.uk independent.co.uk By supplementing with compounds already available as dietary supplements, “we may have a new path toward treating age-related cognitive decline and Alzheimer’s,” Dr. Brewer said independent.co.uk. The findings, published in GeroScience, caution that more study is needed, since nicotinamide taken orally isn’t very bioavailable and delivery methods must be improved independent.co.uk. Still, this discovery highlights GTP energy loss as an overlooked driver of brain aging independent.co.uk. It suggests that relatively simple interventions – perhaps high-dose vitamins or nutritional antioxidants – could one day complement Alzheimer’s treatments by rejuvenating the brain’s natural housekeeping mechanisms.

Industry Deals, Pricing, and Market Moves

Novo Nordisk’s $550M RNA Gamble: Facing fierce competition in the obesity drug arena, Novo Nordisk is striking out in new directions. The Danish pharma giant announced a multi-year research collaboration with California’s Replicate Bioscience that could be worth up to $550 million fiercebiotech.com fiercebiotech.com. Novo will fund Replicate’s work on self-replicating RNA (srRNA) technology and gain exclusive global rights to any resulting therapies for cardiometabolic diseases like obesity and type 2 diabetes fiercebiotech.com fiercebiotech.com. Unlike conventional mRNA (as used in COVID vaccines), Replicate’s srRNA molecules copy themselves inside cells, meaning a tiny dose can generate a high yield of therapeutic protein. This platform could lead to novel long-acting treatments – for example, vaccines or gene-silencing therapies – that aid weight loss or metabolic control. Replicate’s only clinical-stage program so far is an srRNA rabies vaccine that just passed a Phase 1 trial, but its broader pipeline (vaccines for EBV, and oncology targets) intrigued Novo fiercebiotech.com. Executives on both sides hailed the partnership. “This combines the strength of Replicate’s proprietary srRNA library with Novo Nordisk’s therapeutic and clinical insights,” said Replicate’s chief business officer Rachael Lester fiercebiotech.com. Novo’s VP of nucleic acid research Karina Thorn added that Novo is continually looking to “raise the innovation bar” by combining its core expertise with new modality platforms fiercebiotech.com. The deal is part of Novo’s strategy to stay ahead as rival Eli Lilly surges with its own obesity drugs. Novo’s flagship GLP-1 drug Wegovy (semaglutide) still dominates the market, but Lilly’s Mounjaro (tirzepatide) is closing in. Novo even ousted its CEO this year due to pressure to accelerate innovation fiercebiotech.com fiercebiotech.com. By betting on cutting-edge RNA therapeutics, Novo aims to ensure it has the “next generation” of weight-loss and diabetes treatments ready in the pipeline.

Weight-Loss Gold Rush Spurs Price Moves: The frenzy around obesity treatments is not only scientific but financial. Eli Lilly temporarily halted U.K. shipments of Mounjaro (tirzepatide) – its diabetes drug widely used off-label for weight loss – in late August, just ahead of a major price increase reuters.com reuters.com. Lilly will raise Mounjaro’s U.K. list price by up to 170% starting September, and the company paused new supply to prevent stockpiling before the hike reuters.com reuters.com. The cost for a month’s highest dose will jump from £122 to £330 (about $445) reuters.com. This unusual move comes as the U.S. government pressures drugmakers to narrow the price gap between American and European markets reuters.com reuters.com. Essentially, U.S. officials (under President Trump’s administration) have pushed companies to raise prices abroad so that forthcoming Medicare price negotiations won’t lead to higher U.S. prices than overseas reuters.com. Lilly’s decision shows that dynamic in action. The company said it has measures to ensure patients can still get their medication (allocating stock to pharmacies to maintain supply for existing users) reuters.com and will resume normal ordering on Sept. 1 reuters.com. However, some U.K. patients and clinicians voiced frustration that a life-changing drug is being throttled due to global pricing strategies. Demand for Mounjaro has exploded as it proves highly effective for weight loss, but its availability and cost now highlight the tricky balance between access and profit in this blockbuster market.

Biotech Funding and M&A Notes: Beyond Novo’s headline deal, mid-year 2025 has seen other notable biotech investments. Cancer immunotherapy startup Wugen raised $115 million to advance trials of its off-the-shelf CAR-T cell therapy for T-cell lymphomas (a rare cancer) clinicaltrialsarena.com. And in the psychedelic medicine space, AbbVie earlier this week agreed to pay up to $1.2 billion for a fast-acting antidepressant drug from Gilgamesh Pharmaceuticals – a bet on novel psychiatric treatments becoming mainstream (this deal closed just before our August 27–28 window) pharmexec.com. Meanwhile, the quest for drug royalties continues to fuel big transactions: Royalty Pharma announced a $950 million agreement to buy a portion of the royalties from an upcoming Amgen cancer therapy ca.finance.yahoo.com, injecting cash into biotech development. These moves reflect a broader trend: pharma giants are flush with cash from recent sales success (especially in obesity and autoimmune drugs) and are eagerly reinvesting in acquisitions, partnerships, and royalty deals to secure the next wave of innovations. Investors are selectively optimistic – while major players strike rich deals, some small biotechs are pivoting away from the sector. (In a quirky twist, one struggling biotech, SciSparc, announced a reverse merger that will transform it into an electric vehicle distributor stocktitan.net – underscoring the challenges faced by tiny drug developers in the current market.) Overall, the flow of capital into new therapeutic modalities and the high value placed on promising drug candidates suggest that the second half of 2025 will remain very active for biotech financing and consolidation.

Global Public Health Alerts & Guidance

Cholera Crisis in Nigeria: In West Africa, public health officials are racing to contain a cholera outbreak in Zamfara state, Nigeria, that has infected over 200 people and killed at least 8 as of August 28 reuters.com. The water-borne illness erupted in 11 rural communities that lack clean water and proper sanitation – conditions ripe for cholera’s spread. Local health facilities have been overwhelmed; many sick patients are being treated at home due to the absence of nearby clinics reuters.com. “We have over 21 patients presently admitted, although three died due to delays in reaching the hospital,” reported a village leader in one hard-hit town reuters.com. Efforts to get help are hampered by insecurity: Zamfara has been the epicenter of violent banditry, where armed gangs roam and frequently block roads or kidnap travelers reuters.com. One resident noted they lack basic supplies like IV fluids because “bandits prevent us from going to the city” for medicine reuters.com. The outbreak highlights how conflict exacerbates disease outbreaks – patients can’t safely seek care or clean water. A federal lawmaker, Sulaiman Abubakar Gumi, pleaded for urgent intervention: “Any delay will cost more lives, especially among women and children,” he warned, urging the state government and international NGOs to send emergency response teams and set up cholera treatment centers reuters.com. As of Aug 28, Zamfara’s state authorities had yet to issue an official statement reuters.com. Nigeria faces cholera outbreaks nearly every rainy season, but insecurity in Zamfara has made this year’s especially hard to control. The WHO and UNICEF are monitoring the situation; aid groups are standing by to assist if access improves. Health experts stress that providing clean water, rehydration salts, and antibiotics will be critical to stem the deaths, and they call for long-term investment in water sanitation infrastructure to prevent future outbreaks.

Other Health Alerts and Guidance: No new WHO global health emergency was declared in the past two days, but health agencies remain vigilant. In the Western Pacific, authorities continue to battle a dengue fever surge – for example, American Samoa extended a public health emergency after a spike in dengue cases this summer unicef.org. And in Southeast Asia, researchers are tracking Nipah virus spillover in India’s Kerala state (as of early August, 4 cases were confirmed in a recent cluster) who.int. While not spreading widely at the moment, these sporadic outbreaks keep experts on alert for potential escalation. On the policy front, Singapore’s government announced it will impose harsher penalties on e-cigarettes laced with drugs starting next month, as part of a broader crackdown on vaping and illicit substances reuters.com. And in the U.S., the FDA and CMS formed a joint advisory panel to explore new ways to combat chronic diseases and reduce healthcare costs reuters.com. Public health watchers are also awaiting the new 2025 dietary guidelines – this week HHS Secretary Kennedy and Education Secretary McMahon called for comprehensive nutrition education reforms in schools hhs.gov, indicating that diet and chronic disease prevention remain a priority despite other controversies. As these various alerts and initiatives show, the global health community is juggling immediate crises like cholera and dengue alongside longer-term battles against chronic disease and misinformation. Public health guidance can change quickly (as seen with COVID vaccines), so experts emphasize the need for clear communication and community trust to ensure life-saving interventions reach those in need.
