They will miss Lake Louise and Beaver Creek. It is also not possible to start in the US without the vaccines. So Lara Gut-Behrami will also maybe miss the Giant Slalom in Killington, if her second vaccination is not 14 days ago then.
If Kryenbuhl or Weber want to start at the Olympics, they have to miss Wengen and Kitzbühel, so only have the Events in Val Gardena and Bormio to qualify.
Men‘s Downhill Training starts already on 03. February, so they would have to go in quarantine on 12. January, if they want to participate.
