Been hearing about more and more breakthrough cases that are undoubtedly Omicron. Locations have included Washington state, California, New England, the UK, Australia, New Zealand. Meaning first hand reports by people on ski forums who are regular posters and fully vaccinated. Includes some of the elderly parents of the poster. No one is talking about symptoms for more than a week or so in these cases.
Also saw a post from an ER doc in Washington who said that while many people are coming to the ER and testing positive in the last 10-14 days, few have needed to be admitted. Don't know if those are vaccinated or unvaccinated people though.
