If the WHO guesses wrong, and we are invaded by flus for which we have not received artificially induced immunities, a lot of people will come down with the flu. One of the most intractable of immunology's problems today is a disease that attacks the immune system itself, AIDS, or Acquired Immunodeficiency Syndrome, caused by the Human Immunodeficiency Virus (HIV). Everyone, particularly those with weakened immune systems, is encouraged to get their flu shot, which causes the body to produce its own antibodies to repel those particular flus. Most of the disorders addressed by immunology are those in which the body's own immune system isn't sufficient to ward off disease, and the immune system must be supplemented with external assistance.

Arthritis and asthma are diseases of the immune system caused by the body's hypersensitivity to certain substances.
Flu shots are an example of immunology in action.
Immunology is both the study of the human immune system and the field of medicine that treats diseases of the immune system. A variety of drug therapies today can strengthen the immune system and prolong the life of the AIDS patient, but there is currently no cure. The treatment of disorders as simple as common allergies and as complex as AIDS all fall under the immunology category.
