Vaccines work by exposing the body to a weakened strain of a virus that it is able to fight off easily. This allows the body to produce antibodies and memory cells specific to that virus. When the body is exposed to the virus again, it will be able to fight it off even easier and faster with the help of the antibodies and memory cells.

# data[].attributes.body
A category of white blood cells used in the third line of defense.

# data[].attributes.body
Specific lymphocytes that live longer and can remember antigens, giving the body further long-term protection.

# data[].attributes.body
Produce antibodies after then detection of a specific antigen.

# data[].attributes.body
A category of white blood cells used in the third line of defense.

# data[].attributes.body
Type of lymphocytes that bind to the surface of other cells that display the antigen and trigger a response by releases cytokines (interleukins). Can be helper T cells, which display the antigen, or killer T cells, which assist in attacking the pathogen. (Can only recognize foreign antigens)

# data[].attributes.body
Produced in response to specific antigens, provide future protection from that antigen.

# data[].attributes.body
Tiny hairs throughout the body move harmful particles up to the throat, where they are usualy ejected from the body through coughing or sneezing, or swallowed and removed as waste.

# data[].attributes.body
Work to catch pathogens in the nose before they completely enter the body.

# data[].attributes.body
A type of cytokines. They are produced at the site of the infection and are responsible for activating other immune system cells such as mast cells for inflammation.

# data[].attributes.body
Phagocytes engulf or eats the pathogen or flue virus and stimulate other immune system cells. This is also not specific because it doesn't matter what the pathogen is.

# data[].attributes.body
Activate the inflammatory response to try and kill the pathogen.

# data[].attributes.body
Macrophages are a type of phagocytes that can surround and kill pathogens.

# data[].attributes.body
The mucous membrane and throat get inflamed. It may cause a sore throat and excess mucus.

# data[].attributes.body
Natural killer cells kill the cells that are infected by the virus. This action is not specific.

# data[].attributes.body
Another type of physical barrier between pathogens and the body. Can also trap pathogens.

# data[].attributes.body
Establishes a physical barrier between pathogens and the inside of the body.

# data[].attributes.body
Acquired and built up throughout life.

# data[].attributes.body
Available at birth, not acquired throughout life.

# data[].attributes.body
If the first and second lines of defense are unsuccessful, the body will initiate a specific line of defense.

# data[].attributes.body
If the first line of defense fails, the body initiates another nonspecific response. It will kill things it deems to be infected cells, regardless of the specific infection.

# data[].attributes.body
The pathogen is initially blocked by physical barriers, such as skin and mucous membranes.

# data[].attributes.body
Influenza B pathogen attempts to enter the body.
