The immunological correlates of protection from SARS-CoV-2 infection and COVID-19 have yet to be elucidated. Pre-existing neutralising antibody seemed to have afforded protection against re-infection in people on board a fishing vessel where there was an outbreak of SARS-CoV-2 with a high infection attack rate. 20 Alongside the risks of severe morbidity and mortality and of disease transmission, this framework stipulates two additional criteria for equitable vaccine allocation-namely, risks of acquiring infection and of negative societal impact. If COVID-19 vaccines have acceptable effectiveness in reducing morbidity and mortality in high-risk groups, they would have an important role, irrespective of impact on transmission and population immunity.	./cache/cord-260559-n8i52e8q.txt	./txt/cord-260559-n8i52e8q.txt
