Oxford vaccine chief fires back: ‘It’s not about herd immunity’
The head of the Oxford Vaccine Group has defended its COVID-19 vaccine against Australian criticisms, saying discussions about herd immunity have distracted from the need to protect people from severe illness.
A debate has emerged over Australia’s plan to vaccine most people with the adenoviral vector COVID-19 vaccine developed by the University of Oxford and AstraZeneca, with some doctors expressing concern that the reported overall efficacy rate of 70% is not enough to reach herd immunity.
