USA Today’s Kevin Maney thinks Google Health may launch next week based on a comment by Marissa Mayer, Google’s VP Product, during a meeting.

Vertical search makes a lot of sense for certain categories, and Health is one of them. Just compare the results for any health related search from Healthline, a well funded new health search site, to a standard search on Google.

The question I have is will Google do any content aggregation or even…gasp…original content…to turn their health search site into more of a Google Finance-like portal. Either way, Google Health will need to be very good to be better than Healthline.
