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.

Which part of a specifics immune response?
Looking for antigens is part of a specific immune response.
Specific immune response?
The specific immune response is a targeted immune response mounted by the body against a particular pathogen. It involves the activation of lymphocytes (T cells and B cells) and the production of specific antibodies to recognize and neutralize the invading pathogen. This response provides long-lasting immunity against future exposures to the same pathogen.
Does aspirin depress the immune response?
yes..because it surely makes the nerves innactive a bit resultining in long term immune effect
What is the function of adjuvant in immune response?
When mixed with an immunogen, it enhances the immune response against the immunogen
Which is more rapid primary or secondary immune response?
Secondary Immune Response is more rapid.
Explain the difference between innate response and an acquired response?
The innate immune response is the body's immediate, non-specific defense mechanism against infections. It is always ready to respond to invaders. The acquired immune response is specific to a particular pathogen and involves the production of antibodies and memory cells for long-term protection. It takes time to develop but provides a targeted defense against specific pathogens.
Which immune response involves antibodies?
Specific response
What is meant by secondary immune response?
when it an infection or something gets past the first immune response then your body uses a different response or after immunisation
What is a characteristic part of the secondary immune response?
Memory B cells are a characteristic part of the secondary immune response. They are formed during the primary immune response and can quickly recognize and respond to a previously encountered antigen by producing antibodies. This results in a faster and more robust immune response upon subsequent exposure to the same antigen.
How long do the effects of plasmapheresis last?
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 they must be?
in order for antigens to incite the immune response the y must be ?
What directs the immune response by signaling between the immune systems?
lymphokines
