In a test-negative design case-control study, Dr. Thiago Cerqueira-Silva and colleagues, investigate the effectiveness of mRNA boosters after homologous primary series with BNT162b2 or ChAdOx1 against symptomatic infection and severe COVID-19 in Brazil and Scotland.
Older people, those with multimorbidity, and those with specific underlying health
conditions remain at increased risk of COVID-19 hospitalisation and death after the
initial vaccine booster and should, therefore, be prioritised for additional boosters,
including novel optimised versions, and the increasing array of COVID-19 therapeutics.
