Hundreds of flu cases have already been confirmed in the Tr-Cities this season, and health experts say there could be a rise in cases soon. Have you ever heard that if you get a flu shot, sometimes it gives you the flu? It's simply not true. If you get the flu after you get a flu shot, it's because the virus was already in your system. So get a flu shot and rest easy. Yes, some places have had a shortage of flu shots, but it looks like every location that provides them has been fully re-stocked.
