Ahhh never mind. You didn’t actually read the data. You just scanned through it. If you look look more thoroughly it doesn’t address omicron at all. The last data I could see was from December 14. Omicron was not prevalent at that point, delta was. The vaccine offered some, but not much, protection against infection from delta.
If you look at vaccine doses per person over time, and graph of cases per person over time, in one of the most vaccinated countries in the world, you see not only no effect, but the worst effect happening at the most-vaxxed time. If they stop transmission the effect at this point is miniscule. If you didn't label the first graph, you might be tempted to blame it for the second graph.
(nota bene, vaccines show a clear effect in reduction in death.)

Actually Denmark has even more vaccines, and an even greater case uptick: https://ourworldindata.org/explorers/coronavirus-data-explor...
