a vaccine puts a strand of the virus into your blood system so that your body can learn how to fight against it. It affects the immune system by making it weak for a few days but overall it becomes more immune to the disease.

# data[].attributes.body
The b makes antibodies while the t attacks the cells that already have the virus. (Make killer cells)

# data[].attributes.body
Skin swelling

# data[].attributes.body
they are required for almost all adaptive immune responses. They not only help activate B cells to secrete antibodies and macrophages to destroy ingested microbes, but they also help activate cytotoxic T cells to kill infected target cells.

# data[].attributes.body
The virus make copies of itself and multiplies throughout your body

# data[].attributes.body
Takes over a healthy cell in order to reproduce more virus cells.

# data[].attributes.body
the virus makes its way into your body and destroys a cell and moves onto another cell.

# data[].attributes.body
T cells can only recognize viral antigens outside the infected cells whereas B cells can recognize the surface antigens of bacteria and viruses.

# data[].attributes.body
The virus makes its way into the body where it then infects a cell and makes copies of itself so that it can spread to other cells throughout the body.

# data[].attributes.body
swelling/inflamation

# data[].attributes.body
The virus starts to take over the healthy cells and create more infected ones

# data[].attributes.body
They find antigens then send messages about the location of viruses throughout the body

# data[].attributes.body
inflammation, fever

# data[].attributes.body
Vaccines introduce a killed antigen into the body so the immune system can produce antibodies against it and create immunity to the disease.

# data[].attributes.body
B lymphocytes are found in the bone and produce antibodies and T lymphocytes are found in the Thymus glands and produce killer T cells

# data[].attributes.body
Helper t activate B cells that are displaying antigen, causing clonal expansion, they also activate cytotoxic cells.

# data[].attributes.body
the skin protecting the body from various viruses

# data[].attributes.body
Vaccines help create antibodies by making antigens. This allows the immune system to recognize the antigen when it comes around again. Then your body will produces a ton of antibodies ,so before you feel the effects of the virus, it has already been defeated.

# data[].attributes.body
Activate the killer t cells.

# data[].attributes.body
Vaccines help the immune system recognize a virus so that in the future, it can fight off that virus, vaccines help to strengthen the immune system.

# data[].attributes.body
swelling

# data[].attributes.body
gain entry to makes copies of itself that destroy the cell and spread off to infect other cells

# data[].attributes.body
b create antibodies- humuoral
t create killer cells- cell mediated

# data[].attributes.body
help create antibodies to fight off the virus

# data[].attributes.body
activate t cells to kill infected target cells

# data[].attributes.body
viruses can replicate and create other viruses. This is possible as they can adapt very easily to any environment and any host. They are made to survive very difficult conditions.

# data[].attributes.body
protein defenses, cellular defenses

# data[].attributes.body
B-cells can connect to antigens right on the surface of the invading virus or bacteria. T-cells can only connect to virus antigens on the outside of infected cells.

# data[].attributes.body
Vaccines introduce a killed/disabled antigen into the body so the immune system can produce antibodies against it and create immunity to the disease.

# data[].attributes.body
T cells stimulate B cells through the binding of CD40L with CD40 on B cells, through interaction of other TNF:TNF-R family ligands, as well as by the directed release of cytokines.
