The study was approved by an independent ethics committee. The nasal spray will be available in a year or two.
As noted by the representative of the Nucleus Network (Brisbane), Dr. Paul Griffin, the new vaccine may be more effective than AstraZeneca and Pfizer. In addition, many people who are afraid of injections will be able to decide on vaccination.
“The main benefit is, when we give the vaccine via the same route that the pathogen or the virus gets in through, then hopefully the response will be more adept at actually stopping the virus getting in,” he said. “So, we will get a response that is particularly active at that site, which will hopefully mean that people are much less likely to get infected, which is something that we really want to see with vaccines for this virus.”
By this time, vaccinations in Australia are taking place at a slower pace than in other countries. Among the reasons are problems with the supply of drugs, lack of planning on the part of government agencies and the indecision of Australians themselves, reassured by the relatively low level of coronavirus infection in the country. Two Covid vaccines, AstraZeneca and Pfizer, are currently approved for use in Australia.
