Evaluation of COVID-19 Booster Vaccine Effects

Dear Colleagues,

Three years have passed since the COVID-19 outbreak, which has claimed millions of lives. Vaccination is considered as the most effective approach for the prevention and control of COVID-19. However, the protective efficacy of the COVID-19 vaccines weakens over time after vaccination. Additionally, the effectiveness of the vaccines dramatically declines for different variants. Booster vaccination has shown a higher level of antibody production. Therefore, booster vaccines have been administered in order to improve the immunization level of various populations. The effects and durability of booster vaccination need to be evaluated and monitored frequently. This Special Issue provides a platform for communication and discussion on this important issue. This Special Issue will feature original research articles and reviews related to, but not limited to, epidemiology studies, vaccine efficacy (effectiveness) evaluation, new delivering systems for vaccines, development of new vaccines, prediction models to evaluate vaccine effects, pathogens, interactions between viruses and hosts, molecular mechanisms, molecular evolution, and so on.
