The flu vaccine is in

Here comes the flu vaccine.

For the first time, the seasonal flu vaccine is recommended for all men, women -- including pregnant women -- and children over age 6 months. Exceptions include only those allergic to eggs or those with other health issues that make vaccination unwise, WebMD reports.

There will be plenty of vaccine. Manufacturers tell the CDC they'll have 170 million doses on hand. They've already begun shipping the vaccine across the nation.

This isn't about the H1N1 swine flu. That U.S. emergency ended in June, and the World Health Organization this week called off its pandemic alert. This time it's about seasonal flu, joined but no longer dominated by the 2009 H1N1 swine flu. The CDC warned that the H3N2 flu bug has begun popping up in states across the U.S.

Yikes!
