If someone has been diagnosed with the H1N1 flu virus, do they have immunity and will they still need a vaccine.
In most cases, when a person is infected with an influenza virus and recovers, they develop antibodies that provide them with immunity to that particular virus. Therefore, in the case of the H1N1 flu virus, the vaccine will be recommended to everyone, but is not necessary for people who have had a laboratory confirmed H1N1 flu virus infection.
