The study " BA.2.12.1, BA.4 and BA.5 escape antibodies elicited by Omicron infection " was published today (June 17, 2022) in the journal Nature in the form of an Accelerated Article Preview. , the study pointed out that Omicron's BA.2.12.1, BA.4 and BA.5 are more infectious than the current mainstream BA.2, and can escape the antibodies produced by BA.1 infection, the possibility of re-infection in the future Sexuality has increased, and vaccines designed against BA.1 may not provide adequate protection.
Do BA.4 and BA.5 have stronger immune escape ability? Is there an increased risk of reinfection? Do drugs and vaccines still work? Specially industry email list invited experts from the Taiwan Science and Technology Media Center analyzed the key points of this research and expressed their opinions. It will help the public understand the virus characteristics and infectivity of BA.4 and BA.5. Citation: Cao, Y., Yisimayi, A., Jian, F. et al.

Qi Jiayu (Associate researcher-level attending physician, Institute of Infectious Diseases and Vaccines, National Institutes of Health) June 29, 2022 The number of infected cases is increasing rapidly after Omicron BA.1 variant virus subtypes BA.2.12.1, BA.4 and BA.5 have been identified in several countries. Taking the UK as an example, at the end of June this year, the number of cases infected with BA.4 and BA.5 already accounted for more than half of all ne
