Comparative effectiveness of the BNT162b2 and ChAdOx1 vaccines against Covid-19 in people over 50
Abstract
Several vaccines have been approved for Covid-19 and effectiveness data could guide public health decisions on vaccine usage. Here, the authors compare effectiveness of BNT162b2 and ChAdOx1 vaccines in people over 50 in the UK and find that BNT162b2 confers lower risk of infection and hospitalization.
