Aussie scientists cast doubt on low-efficacy AstraZeneca coronavirus vaccine

A group of Australian scientists called on the country’s federal government to review its use of AstraZeneca’s coronavirus (COVID-19) vaccine. They argued that the jab is ineffective at generating herd immunity and has a low efficacy rate. However, the central government has rejected the proposal to pause the rollout scheduled next month. The opposition Labor Party and some immunologists have called on the Australian government to procure additional doses of the Pfizer/BioNTech and Moderna vaccines. Clinical trials for these two vaccines have shown that they have higher efficacy rates than the one produced by AstraZeneca.
