Do you have antibodies against Swine Flu?

Answer 1

If you have been exposed to the virus that causes H1N1 Pandemic Swine Flu, either from having had the flu or from getting a vaccination for it, then your body will have made antibodies to the virus, as long as you have a healthy immune system. Once your body has made antibodies to that virus, you are immune to the disease if exposed in the future, as long as it is the exact same virus and not a mutated form of it. This immunity is provided by the previously made antibodies.

Answer 2

No, Tamiflu does not cause you to have an immune response and build antibodies like a vaccination does. Tamiflu is an antiviral medicine that just prevents the cells that have produced replications of the virus from opening to release the new viruses. That means they can't get out to invade other cells. The result is that you have a shortened duration of illness with less severe symptoms.

Answer 3

Yes. Exposure to flu build up life long antibodies for that particular strain. Flu virus changes outer coat almost yearly. So the individual can get the flu almost yearly. So if you are exposed to the flu virus yearly, then the severity of the infection is relatively less. ( Unless there is mutation of virus causing drastic change in it's antigenicity.)

Answer 4

Yes, unless the person has a weakened or compromised immune system. See the related questions below for more information about flu and antibodies.
