Question 16
How does the flu vaccine, an injection usually composed of a small amount of live but not harmlul
viral cells, prevent a person from getting sick with the flu virus?
It stimulates the host cell to produce antiviral toxins, which are released
continually into the respiratory tract, to destroy the viral cells even before they
are recognized by white blood cells.
А
B
It prevents the flu virus from converting host cells into pathogenic bacterial cells,
which are the source of a person's symptoms, as it is the bacterial cells that
damage the respiratory tract.
Ос
It initiates the production of memory cells specific for that year's predicted flu
virus. When the flu virus is inhaled, it is recognized quickly by memory cells and
destroyed.
D
It gives a person a mild case of the flu all year long. Since the person already
has an active form of the flu virus, it is impossible to infect that person again
with another flu virus.
