Should you get swine flu are you in risk of getting it again?

No, if you have it you will be immune to it after that. However, viruses are able to mutate to slightly different strains rapidly. If that happens and you are exposed, you may still have some immunity, but you may not, in which case you could get the flu from a similar but different form of the virus.

Do you have to actually get sick with a particular flu to become immune to it OR is exposure to someone with flu without getting ill yourself enough to become immune?

Being around other people who have the flu will only make you immune if you come down with the flu yourself. There are no etherial substances (none discovered as yet, at any rate) that pass through the air to healthy people, thus immunizing them. To the contrary, influenza virus particles easily waft through the air, and, depending on the flu variant, arrive at their destination (your throat perhaps?) ready to infect someone else.If you're interested in becoming immune to a given flu, we recommend getting immunized with a vaccine approved by your government. For most people, that's far, far better than actually becoming infected.


Can you get the same flu again My whole family is sick and I want to know if we can pass it back and forth or will it be gone once we each have it once?

Getting the flu shot is crucial for individuals without a spleen because they are at a higher risk of infection due to a weakened immune system.

It is recommended to consult with a healthcare provider to determine the most appropriate vaccination schedule.
