Trials of a swine flu vaccine ordered by the federal government will begin today.
The Australian government's ordered 21 million doses of the vaccine being made by biotechnology company CSL.

The Royal Adelaide Hospital trials will take about seven months to complete but CSL says there'll be enough initial results for the government to plan distribution from October. 240 volunteers will take part in the trial with some to get a single dose and others a double dose.
