I came back from the NOA tournament in Las Vegas with a full car due to Tony Padron's accident where his car was no longer drivable, but he and his passengers were all ok, so they drove down and back with me.  Winter accidents due to snow and ice are frequent but normally less sever than dry road accidents.  Anyway, everyone in my car got Covid except me.  I tested negative and have had the Molina booster.  Tony was never vaccinated, since he moved here recently from Saint George where folks have never taken it very seriously.  We stopped at a restaurant there where I noticed that none of the workers wore masks.

Results We included 3,442 Omicron-positive cases, 9,201 Delta-positive cases, and 471,545 test-negative controls. After 2 doses of COVID-19 vaccine, vaccine effectiveness against Delta infection declined steadily over time but recovered to 93% (95%CI, 92-94%) ≥7 days after receiving an mRNA vaccine for the third dose. In contrast, receipt of 2 doses of COVID-19 vaccines was not protective against Omicron. Vaccine effectiveness against Omicron was 37% (95%CI, 19-50%) ≥7 days after receiving an mRNA vaccine for the third dose

Conclusions Two doses of COVID-19 vaccines are unlikely to protect against infection by Omicron. A third dose provides some protection in the immediate term, but substantially less than against Delta.
