Are there any age related issues with getting the flu shot? I have heard that in some people it can actually make you sicker. My parents are in their late seventies.
Yes it is worth getting the flu shots as it protects you from the expected influenza viruses. The elderly are especially vulnerable to potentially life threatening infections and should get this every year. Some people have an exagerated response the the flu vaccines, but this is the immune system gearing up to protect the recipient from the flu viruses. It can save lives.
