AbstractCoronavirus disease-19 (COVID-19) mRNA vaccines are the mainstays of mass vaccination campaigns in most Western countries. However, the emergency conditions in which their development took place made it impossible to fully characterize their effects and mechanism of action.

Predicting the efficacy of variant-modified COVID-19 vaccine boosters
As a result of the emergence and circulation of antigenically distinct SARS-CoV-2 variants, a number of variant-modified COVID-19 vaccines have been developed. Here we perform a meta-analysis of the available data on neutralisation titres from clinical studies comparing booster vaccination with either the current ancestral-based vaccines or variant-modified vaccines. We then use this to predict …
