Vaccine hesitancy is still high despite more than 14million Australians being in lockdown with an epidemiologist describing the campaign against AstraZeneca as a 'baffling public health disaster'. An Essential Media poll found 41 per cent of those delaying their first vaccine shot were waiting for more Pfizer doses to be more readily available from September, following four deaths from the AstraZeneca jab. While Australia has plentiful supplies of AstraZeneca, just 14.1 per cent of Australians over 16 were fully vaccinated against Covid, as of July 19, despite the Indian Delta strain being more contagious, Department of Health data showed. That is well below the herd immunity level of more than 80 per cent needed or the 70 per cent figure Prime Minister Scott Morrison is advocating to avoid more lockdowns.
