A clarification to our contest announced yesterday, in which the first person to correctly predict the Senate vote on the nomination of Kansas Gov. Kathleen Sebelius to be the next secretary of health and human services wins his or her own personal ScuttleButton puzzle.

The vote we are looking for is NOT the final confirmation vote. It's the initial vote — it may even be a procedural vote — in which Democrats are hoping to get more than the 60 votes needed to shut off a Republican filibuster. That's the vote everyone is watching, and that's the vote that matters. Especially when it comes to a personal ScuttleButton puzzle.

As we discussed yesterday, filling that Cabinet post has undertaken a new urgency in the wake of the spreading swine flu virus.

To help people understand more about the potential crisis — 50 cases have now been reported in the U.S. — NPR has launched a new blog, Flu Shots. The blog will track news about the virus from all around the world.
