Abstract: Generally, the neutralizing antibodies may bind specifically to the invading virus particles, and prevent the virus from entering host cells and developing diseases. However, in some cases, these antibodies not only fail to function well, but also aggravate the clinical manifestations of the disease, known as antibody-dependent enhancement (ADE) that leads to vaccine-enhanced disease(VED). In this article, we investigated and analyzed cases of ADE that had occurred in previous clinical studies or during animal experiments related coronavirus vaccines, and the potential function mechanisms of ADE, and reflected on safety issues concerning the development of coronavirus vaccines, so as to provide reference for the early detection and recognition of ADE and risk control.

Key words: antibody-dependent enhancement, SARS-CoV-2, vaccine, safety, risk control
