Conclusions
SARS-CoV-2 infection
SEQUELAE, SARS-COV-2 INFECTION
In this population-based data, the effectiveness of the BNT162b2 against COVID-19 appears better than the ChAdOx1 vaccine for SARS-CoV-2 infection and hospitalisation for COVID-19. Although our findings suggested that the BNT162b2 vaccine may have a slightly better effect on lowering the SARS-CoV-2 infection rate and hospitalisation for COVID-19 than the ChAdOx1 nCoV-19 vaccine, both vaccines are effective against COVID-19 and its severe sequelae and should be encouraged to receive whichever vaccine is available.
