The original paper [0] the article you quoted is based on doesn't say that the vaccine is better than natural immunity, just that it is different: > Therefore, antibody immunity acquired by natural infection or different modes of vaccination may have a differing susceptibility to erosion by SARS-CoV-2 evolution. They seem to be saying their tests showed that the vaccine antibodies better handled the receptor mutations they created (how much better? 100%? or 1%?), but that antibodies from a natural infection target other parts of the virus besides just the receptor (possibly offering broader protection). > The neutralizing activity of vaccine-elicited antibodies was more targeted to the receptor-binding domain (RBD) of the SARS-CoV-2 spike protein compared to antibodies elicited by natural infection. However, within the RBD, binding of vaccine-elicited antibodies was more broadly distributed across epitopes compared to infection-elicited antibodies.
