Two Australian university lecturers have revealed why a nasal spray could be the future of Covid-19 vaccinations.
Dr Mike Todorovic and Dr Matt Barton, senior lecturers and medical researchers at Griffith University in Queensland, used their YouTube channel to show where the technology to fight the coronavirus is headed.
'The doorway (to getting the virus) is your nose and mouth, this is why we wear a mask,' said Dr Barton.
'But if it was to get in, we would need to have a method of vaccine that would work at the respiratory level, so this would be a vaccine through a nasal spray, or something like that, which scientists are currently working on.'
A nasal spray could be used before, or shortly after, exposure to a virus, prompting the body to respond faster to protect patients and reduce community spread.
Almost 52 per cent of eligible Australians are fully vaccinated
In the "video, Dr Todorovic, in character acting as a member of the public, asks his colleague how come he can get Covid-19 and pass it on even if he is vaccinated.
He is answered by Dr Omar Khorshid, President of the Australian Medical Association.
'The vaccines that we have available to us against Covid-10 are really effective, but like all medical treatments, they're not perfect,' said Dr Khorshid.
'There is that small chance that you could still contract the virus and have no symptoms at all, and you may even be able to transmit the virus.
