Inside the vaccines are either dead or weakened cells of the disease, so that your body can get used to the foreign cells.

What happens when a foreign microbe enters the body.
When foreign microbes invade, the body sends white blood cells to fight them off. You often get sick (sneezing, coughing, inflamation, fevers) and this is a way of the body ridding of any bacteria.

What's the second line of defense?
Its called 'adaptive immunity', and special cells called B cells and T cells are recruited to fight the microbes and also to record information about them.

How do antibiotics work?
Antibiotics can be bacteriostatic or bactericidal (static = to stop and cidal = to kill)

How do monoclonal antibodies work?
They're antibodies that are made by identical immune cells that are all clones of a unique parent cell. They bind to the epitome (the part of the antigen that is recognised by the antigen).

How do pregnancy tests work?
All pregnancy tests try and find one hormone called HCG. It's produced in the earliest stages of pregnancy, and it tells the uterus to not shed a lining that month.

What are white blood cells?
White blood cells (WBCs), also called leukocytes or leucocytes, are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders

How do antibodies work?
The antigens in the vaccine stimulate your WBC's into making antibodies. the antibodies then destroy the antigen without risk of disease.

What's herd immunity?
the resistance to the spread of a contagious disease within a population that results if a sufficiently high proportion of individuals are immune to the disease.

How do you make monoclonal anitbodies?
B ly,phocytes (make specific anitbodies but do not divide) and tumour cells that don't make antibodies but do divide are merged into a hybridoma cell and then the cells are cloned.
