Alternatively, as University of Bern computational epidemiologistChristian Althausnotedon Twitter, the surge in cases might also be explained if the variant can evade immunity from prior infection or vaccination or it could be somecombinationof immune evasion and a bump up in contagiousness. The final vote was 57-43 but under Senate rules it needed 60 votes to pass.

Omicron has a few more mutations than beta at key places, so it could be that the 3, (unmatched) dose will do a bit worse than it did against Beta.
