Cabinet minister Karen Andrews has warned a vaccine to conqueror COVID-19 could take longer to produce if it proves to be non-protein based.
The minister for Industry, Science and Technology said biotech company CSL already produced protein-based vaccines and would be in a position to start rolling out a COVID-19 vaccine straight away once it was approved.
However, she said there was still significant work to do if the vaccine needed to be non-protein based and it could take longer to roll-out.
"I would hope that we would be able to do it in about the nine-month to 12-month time frame, but I think we need to be really conscious that with a vaccine, there are a lot of variables in there," she told ABC television's Insiders program..
"So we don't have the vaccine proven at this point in time, we don't know what the base for that vaccine is going to be, so we are trying to prepare across a wide range."
Forecasts in this month's budget were based on a coronavirus vaccine being in wide use by the end of next year.
