这句是在被问及 澳大利亚是否还需采用隔离防疫措施时, Swaminathan said说的,意思是,尽管有已接种了疫苗的人,仍需继续采用现有同样预防措施,直到 达到一定水平的群体免疫为止。
Asked by The Sydney Morning Herald and The Age what this would mean for Australia's quarantine program, Swaminathan said "I don't believe we have the evidence on any of the vaccines to be confident that it's going to prevent people from actually getting the infection and therefore being able to pass it on".
"We need to assume that people who have been vaccinated also need to take the same precautions till there's a certain level of herd immunity. This is a dynamic in an evolving field."
