Natural active immunity typically results in longer lasting immunity compared to artificial active immunity. This is because natural exposure to a pathogen triggers a stronger and more diverse immune response, leading to the development of memory cells that can provide long-term protection against future infections.
Active immunity is of two kinds: Natural active immunity: This is acquired when a pathogen enters the body and immune response occurs. This is stored by the memory cells and eliminates the pathogen for the second time as soon as it enters the body. Acquired active immunity: This artificial and it is induced through a artificial source like vaccines.
how using a vaccine may give long term immunity to malaria
Active immunity is generated by your body. So you get active immunity as a result of infections or due to vaccines. Passive immunity is not generated by your body. Here the antibodies are to be supplied. Child gets the antibodies from mother. Alternately you get the antibodies via injections. The effect of active immunity is long lasting. The effect of passive immunity is short lived. So the active immunity is considered as better. The passive immunity has one advantage. It is available with immediate effect, while it takes about two to three weeks, before the effects of active immunity is available.
D. Active natural immunity. Breastfeeding provides infants with natural antibodies from the mother's milk, which helps to protect the baby through active immunity.
Type your answer here... the active immunity antibodies is created by what?
active immunity is the immunity that is stimulated internally as a a result of antibodies entering the body. Passive is stimulated by substances from an external source
exposure to antigen
Active immunity through the humoral response occurs when B cells encounter antigens and differentiate into plasma cells that produce specific antibodies. These antibodies then circulate in the bloodstream and target the antigen for destruction. Memory B cells are also formed in this process, providing long-term immunity upon subsequent exposure to the same antigen.
because it is.
active acquired immunity and passive acquired immunity
Toxoids are involved in active immunity. They are chemically modified toxins that are used as vaccines to stimulate the immune system to produce antibodies against the toxin. This provides long-term protection against the toxin-producing bacteria.
