Stanford Researchers Develop Universal Vaccine Formula Protecting Mice Against Respiratory Viruses, Bacteria, and Allergens

In the realm of medical advancements, a universal vaccine that can protect against any pathogen has long been a Holy Grail — and about as elusive as a mythological vessel.

Stanford Medicine researchers and collaborators have taken an astonishing step forward in that quest, surprising even themselves.

In a new study in mice, they have developed a universal vaccine formula that protects against a wide range of respiratory viruses, bacteria and even allergens.

The vaccine is delivered intranasally — such as through a nasal spray — and provides broad protection in the

Stanford Medicine researchers and their colleagues invented a new vaccine that protects mice from respiratory viruses, bacteria and allergens — the closest yet to a universal vaccine.
