The number of flu-related deaths in Indiana has risen to 21.

State health officials are revealing little about the patients, but they say two were younger than 18 years of age.  A flu shot is recommended for anyone from six months old through adulthood.

The health department says there is no shortage of the vaccine in Indiana, but it may be more difficult to find because of the demand.  A locator can be found at www.Flu.gov.
