Vaccines and Medicines that Prevent Infection and Antivirals that reduce risks
Potential 'holy grail' nasal spray that may protect against COVID-19, flu and pneumonia aims for human trials
February 2026
"The study showed that mice given a drop of the vaccine up their noses were protected against COVID-19, the flu, pneumonia, some bacterial infections, and even dust mite allergens for at least 3 months. The vaccine's success was attributed to it mimicking the signals immune cells use during an infection, rather than trying to mimic pathogens."
Next step is human trials.
Intra-nasal Vaccine now entering clinical trials
"The vaccine offers potent protection against transmission, prevents reinfection and the spread of the virus, while also reducing the generation of new variants," Dr. Liu said.
"Unlike the mRNA vaccine which targets only the spike protein, CDO-7N-1 induces immunity to all major SARS-CoV-2 proteins and is highly effective against all major variants to date.
"Importantly, the vaccine remains stable at 4°C for seven months, making it ideal for low- and middle-income countries."
The vaccine has been licensed to Indian Immunologicals Ltd, a major vaccine manufacturer.
