The chance of COVID-19 infection after vaccination
Abstract: The outbreak of COVID-19 that began in Wuhan, China, has constituted a new emerging epidemic that has spread around the world. There are some reports on illustrated the patients getting reinfected after recovering from COVID-19. Here we provide an overview of the biphasic cycle of COVID-19, genetic diversity, immune response and chance of reinfection after recovering from COVID-19. The new generation of COVID-19 is highly contagious and pathogenic infection can lead to acute respiratory distress syndrome. Whilst most patients suffer from a mild form of the disease, there is a rising concern that patients who recover from COVID-19 may be at risk of reinfection. The proportion of the infected population, is increasing worldwide; meanwhile, the rate and concern of reinfection by the recovered population are still high. Moreover, there are a few evidence on the chance of COVID-19 infection even after vaccination, which is around one per cent or less. Although the hypothesis of zero reinfections after vaccination has not been clinically proven, further studies should be performed on the recovered class in clusters to study the progression of the exposed with the re-exposed subpopulations to estimate the possibilities of reinfection and, thereby, advocate the use of these antibodies for vaccine creation.
