If shown to be successful in clinical trials, this new method of delivery could eliminate the need for repeated dosing, which currently limits patient access and adherence to these therapies. https://medicalxpress.com/news/2026-06-shot-weekly-glp-drugs-dna.html Mon, 29 Jun 2026 12:40:07 EDT news701952181 A new kind of flu vaccine moved a step closer to the U.S. market Thursday as federal health advisers recommended approval of the first made with the same mRNA technology that was key to ending the COVID-19 pandemic. https://medicalxpress.com/news/2026-06-fda-panel-kind-flu-vaccine.html Thu, 18 Jun 2026 14:46:14 EDT news701012712 The first human clinical trial of a universal Sarbeco coronavirus vaccine, developed by the University of Cambridge and spin-out DIOSynVax (DVX) Ltd, has shown that the vaccine is safe and has no significant side effects. https://medicalxpress.com/news/2026-06-ai-universal-vaccine-human-trial.html Sun, 07 Jun 2026 15:20:01 EDT news699866842 Within 24 hours of injecting the first dose of a weight loss medication she received following a visit with a telehealth doctor, Karleigh McClain was admitted to the hospital, she said.

Now, new research coordinated by UMC Utrecht and Amsterdam UMC provides some of the strongest functional evidence yet that autoantibodies (antibodies that mistakenly target the body's own tissues) could play a causal role. The work appears in Cell Reports Medicine. https://medicalxpress.com/news/2026-03-autoantibodies-implicated-drivers-covid.html Tue, 24 Mar 2026 11:00:06 EDT news693562922 Vaccines have traditionally worked by teaching the immune system to recognize a specific virus or bacterium—in effect, showing it a wanted poster for a single suspect. But what if one vaccine could protect against dozens of different infections at once? Researchers have now developed a potential candidate for such a vaccine, and a study in mice, published in the journal Science, offers promising results. https://medicalxpress.com/news/2026-02-universal-vaccine-colds-flu-covid.html Tue, 24 Feb 2026 15:10:06 EST news691168081 Amid a surprisingly severe flu season and a COVID-19 resurgence, those highly contagious respiratory illnesses are drawing the largest share of media coverage and public attention. But it is also the season for another respiratory illness, respiratory syncytial virus or RSV, and RSV cases are "elevated in many areas of the country," according to the Centers for Disease Control and Prevention (CDC). https://medicalxpress.com/news/2026-01-rsv-immunizations-older-pregnant-people.html Wed, 21 Jan 2026 16:50:10 EST news688236541 Self-administered injectable contraceptives have been available in the United States for more than two decades, yet a new study has found only about a quarter of reproductive health experts prescribe it—and many are unaware it's even an option. https://medicalxpress.com/news/2026-01-birth-option-attention.html Thu, 08 Jan 2026 17:00:08 EST news687099421 COVID rarely rates a mention in the news these days, yet it hasn't gone away. https://medicalxpress.com/news/2025-12-covid-booster-shot-lp81.html Tue, 16 Dec 2025 11:29:32 EST news685106942 It may feel like you are surrounded by sniffles and coughs, but flu season activity is still low in many parts of the U.S. https://medicalxpress.com/news/2025-12-winter-virus-season-bad-doctors.html Sat, 13 Dec 2025 06:52:03 EST news684831073 Food and Drug Administration officials have opened a safety review of two injectable drugs used to protect babies and toddlers from RSV, the respiratory virus that sends thousands of American children to the hospital each year. https://medicalxpress.com/news/2025-12-fda-safety-rsv-drugs-babies.html Wed, 10 Dec 2025 04:48:21 EST news684564460 A new way to deliver protective antibodies against COVID-19 was tested in a Phase I clinical trial. Instead of injecting pre-made antibodies into patients, this approach encouraged the body to produce its own antibodies to fight off the disease-causing viruses. https://medicalxpress.com/news/2025-10-clinical-trial-dna-encoded-therapy.html Tue, 28 Oct 2025 09:00:01 EDT news680860730 A widely available and affordable drug has been shown to be effective in treating seriously ill COVID-19 patients, according to a new international study led by researchers at the Australian National University (ANU) in collaboration with King's College London. https://medicalxpress.com/news/2025-09-inhaled-heparin-ventilation-death-severe.html Sun, 28 Sep 2025 07:20:01 EDT news678262658 An mRNA vaccine developed by researchers from Japan suppressed abnormal blood vessel growth or neovascularization in the retina of mouse models. Neovascularization is a condition that is caused by age-related macular degeneration (AMD), a leading cause of vision loss for elderly people. The vaccine can be delivered intramuscularly and is as effective as current therapies that require frequent eye injections, offering a more comfortable and easier-to-administer alternative for treating AMD and other neovascular eye diseases. https://medicalxpress.com/news/2025-09-mrna-vaccine-age-macular-degeneration.html Fri, 26 Sep 2025 13:09:04 EDT news678110941 When a new immunization to protect newborns from respiratory syncytial virus (RSV) became available in late 2023, pediatricians at Temple University Hospital noted an unusually strong early interest from parents. https://medicalxpress.com/news/2025-09-parents-eager-newborns-rsv-hesitancy.html Thu, 25 Sep 2025 11:21:05 EDT news678018062 Four Western states are taking a different approach from the U.S. Centers for Disease Control and Prevention (CDC) on vaccines for COVID-19, flu and RSV. https://medicalxpress.com/news/2025-09-west-coast-states-issue-covid.html Fri, 19 Sep 2025 11:23:08 EDT news677499783 When the first cells appeared on Earth approximately 3.8 billion years ago, viruses were already here to greet them. Ever since, viruses have been devising ways to infect cells, and cells have been responding by evolving ways to stop these infections. This evolutionary dance eventually led to the development of your immune system. https://medicalxpress.com/news/2025-09-immune-drugs-viruses-paradoxically-cancer.html Wed, 17 Sep 2025 12:52:04 EDT news677332321 Health Secretary Robert F.

It works by stopping infection in the nose before the virus spreads through the body. https://medicalxpress.com/news/2025-09-nasal-vaccine-approach-covid.html Thu, 04 Sep 2025 10:04:04 EDT news676199041 Patients with some cancers, autoimmune diseases, and metabolic disorders often endure time-consuming intravenous (IV) infusions to receive the best protein-based treatments available. Because these protein therapeutics require high doses to be effective and are typically formulated at low concentrations to remain stable, IV infusion has been, until now, the only option. https://medicalxpress.com/news/2025-08-drug-intravenous-treatments-quick.html Wed, 20 Aug 2025 14:00:08 EDT news674907624 Although mRNA vaccines saved millions of lives during the COVID-19 pandemic, U.S. Health Secretary Robert F. Kennedy Jr. incorrectly argued they are ineffective to justify the Department of Health and Human Service's recent decision to cancel $500 million in government-funded research projects to develop new vaccines using the technology. https://medicalxpress.com/news/2025-08-fact-focus-rfk-jr-mrna.html Thu, 07 Aug 2025 05:02:37 EDT news673761750 Winter is here, and with it come higher rates of respiratory illnesses.

Kennedy Jr. has made many public statements about vaccines that have cast doubt on their safety and on the objectivity of long-standing processes established to evaluate them. https://medicalxpress.com/news/2025-06-im-physician-hundreds-vaccine-safety.html Thu, 26 Jun 2025 12:09:05 EDT news670158541 The COVID-19 pandemic caused by SARS-CoV-2 infection is marked by excessive inflammation of several organs, leading to multi-organ failure. The recognition of the virus by our bodies triggers severe immune responses, causing a "cytokine storm," which can lead to acute lung injury and acute respiratory distress syndrome. https://medicalxpress.com/news/2025-06-rheumatoid-arthritis-drug-excessive-inflammation.html Tue, 10 Jun 2025 16:56:04 EDT news668793362
