Get vaccinated for the flu, expert suggests

Get your flu shot now, especially if you're healthy. Dr. John Lynch, medical director of infection control at Harborview Medical Center, explains the idea of "herd immunity."

"The more people who get vaccinated, the more of a shield there is against the virus from getting into the community,' he says.

The severity and length of any flu season are unpredictable. However, the 2019 flu has already gone through Australia, and it saw the highest incidence of the virus ever.
