Best Answer

The FLU constantly mutates into different strains. It is possible to get the flu more than once in any given year and even though the immune system has built immunity to one strain, it is possible to catch another.

well getting swine flu twice is about as likely as getting chicken pox twice. it is possible and does happen to people however it is not that common. So u can get swine flu twice however its harder to get it the second time and i do not think anyone has got swine flu for the third time as its basically impossible as the first and second time you have to take tami-flu which helps fight swine therefore making it impossible to get it a third time as the immune system is to strong. hope i helped. please leave feedback on my message board.

Can you catch the same virus twice?

Usually not the same exact one that you had previously, if you are an otherwise healthy person with a healthy immune system.An example is the flu. Influenza is caused by a virus. If you are exposed to an identical version of the flu that you had previously after you have recovered fully from it the first time, then your body should have developed immunity to all genetically identical kinds of flu and you would not get it a second time. However, the flu can change by mutations and if it does change enough that the immune system no longer sees it as identical, then you would not have immunity to the mutated strain. You can get the flu twice, but if the immune system is properly functioning, it would not be the same flu virus.
