Well, we all in our family had flu shots, and pneumonia shots, but it sure didn't stop us from getting the flu. My Dr. said it may have cut it down. I ran high fever and all of that stuff and oldest son had flu shot and couldn't say a word. He was really sick too. There were 7 of us in our family. We're staying home, going no where. Cancelled all of my Dr. visits. That would be the worst place to go. Just waiting it out, to get totally well.
