HAVEN’T I VACCINE YOU BEFORE? According to The Australian ($), co-chair of the Australian Technical Advisory Group on Immunisation Professor Allan Cheng has left open the possibility of a second vaccine rollout to achieve herd immunity, while emphasising that even if it is not achieved through the first phase some restrictions will ease. With those changes unlikely to include Australia’s international border reopening for most of 2021, Cheng explains that the duration of immunity is still an open question, as is whether it’s even possible to achieve herd immunity with the range of vaccines on offer, and that while the AstraZeneca vaccine likely cannot be injected more than twice, the mRNA-based options should allow for multiple doses.
