Doubts about vaccination strategy, soaring vacancies

Australian scientists are proposing a halt in the rollout of the AstraZeneca/Oxford vaccine, which forms the bulk of available vaccine doses in Australia, because its lower effectiveness compared to other vaccines may prevent the country from reaching herd immunity. The key point though is that the AstraZeneca vaccine is as effective in preventing hospitalisations and severe cases of COVID-19 as other available vaccines. The upshot is that the government will press ahead with the rollout and with reopening the economy by Q2 once vulnerable groups have been inoculated.
