Data from the UK suggests that Australians will need two Covid-19 vaccine doses for them to be adequately protected against the Delta variant, and only around five per cent of Australians have had two doses. Public Health England estimates the Pfizer vaccine offers only about 36 per cent protection against the Delta variant after one dose, while the AstraZeneca vaccine offers only around 30 per cent protection after one dose. Protection from the Delta variant rises to 88 per cent for Pfizer and 67 per cent for Astra-Zeneca after two doses. The Delta variant is estimated to be about 50 per cent more infectious than the original Wuhan strain, and Australian health authorities have warned it can be transmitted as the result of "inadvertent" contact between people, sometimes lasting just a matter of seconds.
