The University of Oxford is developing a nasal Covid vaccine which could be more effective than the traditional jabs.
The new method administers a dose of the AstraZeneca vaccine using an intranasal spray device, similar to over-the-counter hay fever sprays.
Scientists say this method may improve protection against infection and transmission.
Nasal vaccines could be the solution to ending the pandemic, according to some experts.
