>>13024984ADE hasn't been demonstrated in the particular betacoronavirus yet. It is possible though.
In any event it's more likely in people with partially neutralizing antibodies developed to bind to other antigens present in/on the virus encountered in the wild than in people with fully neutralizing antibodies with high binding affinities to the spike protein (which is what you get with the vaccine), so getting the vaccine still wins over encountering the virus in the wild. So far it appears that the spike protein's binding regions are pretty highly conserved in the variants that have cropped up so that's an encouraging sign...
