@Blondy My family and I have been having the flu shots for years and I have had one this year on my onc's strong advice. None of us have ever been sick following it. The vaccine is not a live one so, unless you are one of those people who have an allergic reaction, it is not going to give you the flu. However, people may already have come into contact with colds, etc before they have the shot and link it to the vaccine. I had the flu many years ago and came close to being hospitalised - it's nothing like a cold and I would never wish it on anyone. I would suggest that you speak to your onc about it.
