As long as they are an otherwise healthy person, they last for life. However, cold and flu viruses do mutate readily. There are no vaccines for the common cold, and since they mutate so quickly and frequently, antibodies for the original cold would be obsolete very soon after you recover and other colds will be able to continue to infect you.
Similarly, a new modified version of the flu you had (or vaccination you had) may not be affected by the antibodies like the original version was. In that case without a vaccination for that new type (or without having the new or a very similar infection), then you would have to get an exposure or vaccination for the new version to be able to have antibodies that are effective to gain immunization to the new one. As long as the virus is the same virus (exactly) that you had or that you were vaccinated for, then the immunity is lifetime.
What else can I help you with?
Over the long term the body will produce antibodies immunoglobins if necessary to get rid of infection what kind of organic molecules are these antibodies?
Proteins.

Can you gain passive immunity against H1N1?
Theoretically it is possible to get antibodies from the serum of recovered patient of H1N1. But it will be available in very less quantity. Second question is to whom you will give these antibodies. Thirdly the protection will not be lasting. As this is passive immunity.
No HIV antibodies and no HIV means same in HIV screening immunology test?
No, your body takes a certain amount of time to produce antibodies to counter act a pathogen. Therefore you can have HIV but not have antibodies. This difference in time is called the 'Window Period' which averages 28 days, but can be as long as 3 months.
How can your body produce antibodies against dead viruses?
A virus doesn't have to be alive for the body to produce antibodies against it. Antibodies recognize the physical appearance of a virus. By using dead viruses the immune system is taught to look out for a live virus with the same characteristics of the dead one, but you don't risk being infected by the virus.
How does injecting someone with a killed bacteria vaccine protect someone from getting that disease?
There is nothing like killed disease. You have the killed microorganisms. These killed microorganisms are injected to the person. That gives rise to formation of the antibodies. These antibodies protect the person from the attack of the live microorganism.
Do T-cells make antibodies?
No they do not. B cells synthesize the antibodies.
