Universal vaccine for cold, flu, COVID and allergies 'moves a step closer'

#Universal vaccine #Respiratory infections #COVID-19 #Allergies #Stanford Medicine #Nasal spray vaccine #T cells #Human trials

📌 Key Takeaways

  • Universal vaccine shows promise in mouse studies for multiple respiratory conditions
  • Nasal spray approach could replace multiple annual vaccinations
  • Vaccine works by mimicking immune cell communication signals rather than targeting specific pathogens
  • Researchers plan human trials with estimated availability in 5-7 years if funding secured

📖 Full Retelling

Scientists at Stanford Medicine in the US have announced that a universal vaccine against cold, flu, COVID, and allergies has moved a significant step closer to reality following successful studies on mice, potentially replacing multiple jabs currently required for winter respiratory infections. The groundbreaking vaccine, which can be administered as a nasal spray, demonstrated broad protection in the lungs of mice for several months against various pathogens including COVID-19, other coronaviruses, Staph infections, Acinetobacter baumannii, and house dust mites—a common trigger for allergic asthma. Instead of targeting specific pathogens, the innovative vaccine mimics the signals that immune cells use to communicate with each other during infections, stimulating the body's innate immune cells to remain active against diverse respiratory threats. Lead researcher Dr Bali Pulendran expressed optimism about the potential transformation of medical practice if the vaccine proves successful in human trials, envisioning a single nasal spray administered in fall months that could protect against all respiratory viruses, bacterial pneumonia, and seasonal allergens.

Universal vaccine for cold, flu, COVID and allergies moves a step closer, scientists say It is hoped that in the next few years, the vaccine could replace multiple jabs for winter respiratory infections. Thursday 19 February 2026 19:19, UK Why you can trust Sky News A universal vaccine for humans against cold, flu, COVID and allergies has moved a significant step closer following a study using mice, scientists say. The vaccine, which could be given as a nasal spray, has been developed by experts at Stanford Medicine in the US. It may protect against a wide range of respiratory viruses, bacteria and allergy triggers, they claimed. Scientists said the vaccine offered broad protection in the lungs of mice for several months. Vaccinated animals were protected against COVID and other coronaviruses, Staph (which can infect the skin and cause sepsis), Acinetobacter baumannii (which can cause infections in the blood, urinary tract, lungs or wounds), and house dust mites. This form of vaccine, if translated into humans, could replace multiple jabs every year for winter respiratory infections. It also has the potential to work against new pandemic bugs. Lead author Dr Bali Pulendran, from Stanford Medicine, said: "I think what we have is a universal vaccine against diverse respiratory threats. "Imagine getting a nasal spray in the fall months that protects you from all respiratory viruses including COVID-19, influenza, respiratory syncytial virus and the common cold, as well as bacterial pneumonia and early spring allergens. "That would transform medical practice." 3:09 Share 'Public health isn't a culture war' The researchers are now hoping to trial the vaccine on humans. A safety trial would be followed by a larger trial in which patients are exposed to infections. Dr Pulendran thinks two doses of the nasal spray would be sufficient to provide protection in people. He estimates the vaccine might be available in five to seven years, if there is enough funding. Read more from...
