Potential Vaccine and Treatment Developed for Flu and Coronaviruses | Team develops two nasal sprays – an immune activator and a new vaccine – to prevent virus transmission.


A team of researchers has discovered two new ways of preventing and treating respiratory viruses. The team reports the development and validation of NanoSTING, a nasal spray, and the development of NanoSTING-SN, a pan-coronavirus nasal vaccine.

NanoSTING-SN provides the exciting potential towards a universal coronavirus vaccine and may end the cycle of onward transmission and viral evolution in immunocompromised people. As the recent COVID19 pandemic illustrated, the development of off-the-shelf treatments that counteract respiratory viruses is a largely unsolved problem with a huge impact on human lives. “The ability to activate the innate immune system presents an attractive route to armoring humans against multiple respiratory viruses, viral variants and also minimizing transmission to vulnerable people,” said Leekha.
