Nasal universal vaccine shows cross-protection against cold, flu, and COVID in mice

A nasal vaccine candidate that trains frontline lung immunity shows promise in mice for broad protection against multiple respiratory infections (cold viruses, flu, and COVID) by boosting alveolar macrophages and T cells rather than targeting a single pathogen; it may also dampen allergic reactions. Human safety and efficacy remain unproven, and the best-case path to a human-ready vaccine is five to seven years, with protection in mice lasting up to about three months and many unknowns, including effects in older adults and on DNA viruses.

Researchers Unveil Universal Nasal Spray Vaccine Targeting Viruses, Bacteria, and Allergens

Stanford Medicine researchers have developed a nasal spray vaccine that activates the lungs’ innate immune system to provide months-long protection against a broad range of respiratory threats—including SARS-CoV-2, other coronaviruses, bacterial pneumonia pathogens, and even house dust mite allergens—in mice. If safety and efficacy are shown in humans, the approach could reduce the need for multiple yearly vaccines and idea of rapid protection during outbreaks, with Phase I trials moving forward and an estimated 5–7 years before potential availability.
