Active immunity can be natural or artificially developed.
Naturally acquired - a person is exposed to a live pathogen, develops an immune response - and then creates memory T and B cells.
Artifically acquired - a person is given a vaccine (which contains the antigen). This stimulates the same response, without the symptoms of the disease.
Once you have had the flu or the vaccination, you will have lifetime immunity to the EXACT same type of flu. But since the flu virus can mutate very quickly into a new form of virus, if the one you had or were vaccinated for mutates to enough of a different form, it will no longer be recognized by your immune system as the same one, and then you would need another immunization to be fully protected from it and any other new versions of the same flu. Often, however, the mutation is a small enough change that your body can recognize it and still offer you protection from the prior vaccine or bout of the flu.
varies with type of disease. if produced by vaccination also varies with quality of vaccine used.

An innate immune response is something that you are born with, while an acquired immune response is something that your body gains throughout life...
Looking for antigens is part of a specific immune response.

Chuck Norris evokes and maintains an immune response.
yes..because it surely makes the nerves innactive a bit resultining in long term immune effect
When mixed with an immunogen, it enhances the immune response against the immunogen
Secondary Immune Response is more rapid.
Specific response
when it an infection or something gets past the first immune response then your body uses a different response or after immunisation
Beneficial effects are usually seen within several days. Effects commonly last up to several months, although longer-lasting changes are possible, presumably by inducing shifts in immune response.
in order for antigens to incite the immune response the y must be ?
