Immunity is the body’s self-defense against foreign particles or pathogens that can make our body sick. As this harmful pathogen enters our body, the resistance that the body provides against them is an individual’s immunity. Immunity can be divided mainly into two main types; innate immunity and adaptive immunity. Innate immunity is the immunity that an individual has inherited from their parents, while adaptive immunity is the immunity that establishes itself as the person grows. Outside of it, adaptive immunity is of two types; active immunity and passive immunity Active immunity reacts or provides resistance directly against the antigen or pathogen,

Comparative chart

Active immunity is the type of adaptive immunity that comes into direct contact with pathogens, antigens or harmful foreign elements that can make our body sick. In addition, active immunity can be of two types, it can be acquired naturally or it can be acquired artificially. In naturally acquired active immunity, antibodies are produced by the body’s own body, and they also form memory cells, so it remembers which antibody has to make contact with that specific type of foreign particle or antigen attack. On the other hand, in artificially acquired active immunity, antigens are introduced through vaccines against harmful foreign particles and the body produces specialized antibodies and lymphocytes from the vaccinated antigen.

What is passive immunity?

Passive immunity is the type of adaptive immunity that does not need to be in direct contact with bacteria, pathogens, or any other harmful foreign elements to provide resistance. Furthermore, passive immunity can be classified as naturally acquired or artificially acquired. Passive naturally acquired immunity is quite similar to that of innate immunity, since in this the antibodies are transmitted directly or indirectly from the mother to the offspring. When a mother passes the antibody to the fetus through the placenta or passes the antibody through the milk to the baby, this is naturally acquired passive immunity. On the other hand, when the made antibodies are introduced into the body by injection, then it is artificially acquired passive immunity.

• Active immunity is the type of adaptive immunity that comes into direct contact with foreign pathogens, antigens or harmful elements, while passive immunity is the type of adaptive immunity that does not need to be in direct contact with bacteria, pathogens or any other . Harmful foreign elements.
• Active immunity takes more time to develop as the antibodies are produced by the body itself, while passive immunity has a rapid action when the antibodies made are injected into the body.
• Active immunity can be lost for a longer time throughout life, while passive immunity is short-lived, it can be from a few days to months.
• Active immunity has fewer side effects, while artificial passive immunity has more side effects for the body.
