Cassandra Berry, a professor of immunology at Murdoch University, is waiting on her second dose of the AstraZeneca vaccine.

Queensland does not look likely to enter any sort of lockdown following a couple from Melbourne testing positive on the Sunshine Coast, with the state’s response becoming more “pragmatic”.
A needle-free COVID-19 vaccination could be possible, with University of Queensland scientists successfully protecting mice from the virus by administering a US-developed vaccine candidate with a ‘patch’.
A team of scientists from Australia and the US have announced they developed an “experimental” Covid-19 treatment. Russia embarked on the same path months earlier, with a drug now undergoing phase 2 trials, the developer told RT.
