I can’t find this paper but this appears to be only antibody-based neutralization. There are other types of immune response the body relies on (e.g., humoral immunity).

Most people — even “experts” — seem to concentrate on antibodies, but long-term that is not even the most important or durable type of immunity. I think this is just to spur action/create panic, though perhaps not in this particular case. Also, the much-derided J&J vaccine might end up being better long term as it’s very possible it might be more durable.

My guess about Omicron and looking at its sequence/configuration is that the vaccines will still work fine against it, with some mild reductions in efficacy.
