Current vaccines have still been "highly effective" against Delta, so I think that's why this hasn't been done: there's no point in using the big guns now when the existing weapon works well, and you might really need the big gun soon (and you can't know when).
So it's better to keep it in reserve. The question now is, is Omicron "it" ?
- kolbe 5y agoBy their own data, it’s less effective against Delta than the targeted strain. And the massive spike in excess deaths within heavily vaccinated states/countries this past fall was a pretty good sign we would have benefitted from an updated vaccine.

- Auracle 5y ago(Fairly) effective at preventing serious disease/hospitalization. It seems to me the original plan on the vaccines was to reduce r0 below 1 in the population as a whole, but when Delta came along we changed the metrics the vaccines were to be judged by.
- pseudalopex 5y agoOver 90% is more than fairly effective. All vaccines are judged by preventing serious disease and death. Not meeting higher hopes doesn't change that.
- hammock 5y agoThe justification for a vaccine mandate is based on preventing infection and transmission (aka r0), not just disease or death. That is probably on a lot of people's minds.
