Survival curves for all-cause mortality outcome in study of effectiveness of vaccines and antiviral drugs in preventing severe and fatal COVID-19, Hong Kong. Survival curves were generated to compare patients who did not receive antiviral drugs with those prescribed molnupiravir (A) or nirmatrelvir/ritonavir (B) within 5 days after confirmation of COVID-19 diagnosis and to compare unvaccinated patients with those vaccinated with CoronaVac (C) or Comirnaty (D) vaccines.
