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, associate professors and medical researchers at Griffith University in Queensland, used their YouTube channel to show where technology to fight the coronavirus is headed.
“The passageway (to get the virus) is your nose and mouth, which is why we wear a mask,” said Dr. Barton.
“But if it got in, we’d need a vaccine method 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 can be used before or shortly after exposure to a virus, causing the body to react more quickly to protect patients and reduce its spread to the population.
Nearly 52 percent of eligible Australians are fully vaccinated
In the video, asks Dr. Todorovic, acting in character as a member of the public, his colleague how it is that he can get and pass on Covid-19 even if he is vaccinated.
He is answered by Dr. Omar Khorshid, president of the Australian Medical Association.
“The vaccines we have at our disposal against Covid-10 are really effective, but like all medical treatments they are not perfect,” said Dr Khorshid.
‘There is a small chance that you will still contract the virus and have no symptoms at all, and you may even be able to transmit the virus. But in the end, these vaccines are really for preventing those really serious illnesses, including hospitalization and, of course, death.

‘The easiest thing you can do is get vaccinated. If everyone is vaccinated, the effectiveness of reducing transmission will be less of an issue because of course everyone else is immune too,” he adds.
dr. Barton further explains that Covid-19 vaccines work at the level of the blood system.
“What these vaccines do is they prepare the immune system – the B and the T cells – to recognize the virus, so when the real virus comes and infects you, we have the means to kill it.” (The vaccine) significantly reduces the risk of infection.’
Your next Covid injection could go in your nose instead of your arm
dr. Todorovic, again in civilian character, tells his colleague that vaccinated people can still get sick and die.
dr. Barton says these are so-called breakthrough cases.
‘Breakthrough cases there are (there is) a population of vaccinated people and a small percentage can still (get) sick from the virus.’

How a Covid-19 Nasal Vaccine Would Work?
A nasal spray can be used before or shortly after exposure to a virus
It would allow the body to react faster to protect the patient
This would also reduce the chances of spreading in the community
Seven of approximately 100 Covid-19 vaccines in clinical trials are nasal sprays

dr. Khorsid adds: ‘We are really lucky to have access to two super-effective vaccines. They reduce your chance of serious illness with Covid-19 by about 90 to 95 percent, and for medical treatment, that’s really good.
“However, there are some people who can still get sick despite vaccination, most likely people with cancer who had to undergo treatments that reduced their immune response, or people living with a different type of immune deficiency.”
dr. Barton explains that it is very rare for someone who is fully vaccinated to die from Covid. “Looking at UK data, 51,000 people have died from Covid-19 in the last six months of 2021. Of these, 640 were fully vaccinated, so you can see that it is only a very small percentage.’
In America, the CDC (Centers for Disease Control) has shown that you are 11 times more likely to die from Covid if you are not vaccinated.
“(Getting vaccinated) will free up beds in hospitals for people who are sick or otherwise injured.”
