Question
Read the passage and answer the questions.
What is the definition of vaccine?
HEPATITIS B PREVENTION MEASURES
Hepatitis B virus infection is a major hazard. The risk of being infected with
HBV depends on the frequency of exposure to blood or body fluids. Workers
who often work with blood or other body fluids are at most risk. But any
health care worker may be at risk for HBV infection depending on the tasks
that he or she performs.
Two types of products are available for prevention of hepatitis B infection.
The first is the hepatitis B vaccine. This vaccine provides long-term
immunization against infection. A second product, hepatitis B immune
globulin (HBIG), provides temporary protection and is recommended for use
only after exposure to infection.
OSHA (Occupational Safety and Health Administration) regulations require
that training and education programs be made available to all employees
who may be exposed to blood or other body fluids that might carry HBV.
These programs must be provided to employees when they are first hired
and then at least annually. These programs must be offered during working
hours at least once a year and at no cost to the employee. Also, OSHA
requires that the HBV vaccination be offered free of charge to all employees
who may come in contact with infected blood or other body fluids. If an
employee refuses vaccination, he must sign a medical waiver form when he
is first hired and then again annually
Period of rest
Substance used to prevent disease
Substance that causes disease
A method to cure disease
