LINCOLN -- If you haven't gotten your flu shot yet - the Lincoln-Lancaster County Health Department recommends that you do. The LLCHD says the vaccine is important for anyone six months or older but especially for those at high risk of developing serious complications if they get the flu, such as pregnant women and who are 65 and older. It is recommended to get the vaccine yearly because it is the best protection against influenza since the flu viruses are constantly changing. Flu season typically runs from October through April - and peaks in January and February. There were two flu-related deaths in Lancaster County last year.
