Abstract:
SARS-CoV-2 vaccines are effective in preventing COVID-19, but their efficacy in blocking virus transmission is controversial. Although SARS-CoV-2 vaccines can reduce the sources of infection and the possibility of secondary transmission from breakthrough infection cases, their effectiveness wanes over time. Moreover, the emergence of variants with stronger transmissibility and immune escape ability also poses huge challenges to the effectiveness of SARS-CoV-2 vaccines in blocking virus transmission. Therefore, ending the COVID-19 pandemic still requires the continuous research and development of new vaccines as well as the adoption of effective prevention and control measures.
