It's combined with the regular flue shot. I had to get it, not by choice. I personally don't agree with getting it. I survived the having the flu, I survived having Swine Flu, I don't need it, but it wasn't my decision. Nightwork, I agree with you partly on that. Our immune systems are built to fight against such things, and with how "clean" or society is trying to become, it is weakening our immune systems, and making illnesses and allergies easier to get. However, younger children and elderly people I do feel should get the vaccines, as their immune systems are not as strong as teen to middle aged people. Also, people with health propblems, causing them to have weak immune systems would benefit from it. But other than that, there is a lot of nonsense about all these bugs and being clean or dirty that's really screwing up the human life style and body systems.
