The risk of COVID19 reinfection, Breakthrough and Escape, how much will be saved from coronavirus infection after vaccination?

Abstract

symptomatic disease as vaccination, at least for the available follow up period. Despite the substantial advances in all aspects of COVID-19 analysis and data collection over the past year, calculation of the risk of reinfection has been difficult and there are two key reasons for this. The most obvious reason for difficulty is that most individuals around the world who became infected during the first wave of the pandemic did not access a PCR or antibody test and were not admitted to or treated in hospital, and so are not included in many COVID-19 datasets. The second reason is that scientific journals require specific evidence for formal reporting of reinfection, leading to probable under-reporting.
