No. AIDS is not so much a disease as it is a condition. AIDS is a diagnosis received by a medical provider when a person is HIV positive and their immune system has reached a certain level of deficiency.
A person can become immune by being vaccinatedwhich helps the body to develop long-term immunity against a disease.

After a person has had a disease, the lymphocytes remain to produce more antibodies for that pathogen if the disease is encountered again. This is called IMMUNITY.
Immune is an adjective, i.e. your immune system. However, it can be used as a noun in the specific case of talking about a person who is not susceptible to a particular disease.
Vaccines prepare the body to fight off a certain illness or disease. There is a very small amount of the illness in the vaccination, causing the immune system to produce more antibodies to fight off those illnesses. Therefore, you're immune system develops an immunity to the illness or disease. So, if one person develops an immunity to a certain illness or disease, it is highly less likely for them to catch that disease. If they don't get the disease, chances are high that their parents and family won't get it either. Basically, if one child is immunized, he or she reduces the exposure to a certain disease for all around him/her. Hope this helps!
A vaccine.
Vaccines have a minuscule amount of the disease, so your immune system can easily destroy it and then retain in the immune systems memory the best way to destroy it. That is how vaccines work. However if you have an immune deficiency disorder, or a weak immune system, the disease inside the vaccine has a tiny chance of surviving and reproducing causing the disease to infect you.
Immunization is the process by which an individual's immune system becomes fortified against an agent. A person is made either immune or resistant to a disease.
Injecting someone with a killed bacteria protects that person because it causes the immune system to fight off that disease without being infected by it. The body thinks its being invaded by that disease and the immune system destroys it, and this will help prevent you from contracting it.
It Means You Cant Catch It. This Is Usually The Case If You've Already Had It As It Is Unlikely To Have It TwiceYou are immune to chicken pox means you will not catch the infection. So that means you had an attack of chicken pox or you have taken chickenpox vaccine atleast two weeks back.
