What is the primary advantage of using a subunit vaccine?
Very safe, even in people with compromised immune systems
How are recombinant subunit/fragment vaccines produced?
Using the isolated DNA fragment coding for relevant proteins from the microorganism
What is the primary function of a vaccine?
To stimulate the body's immune system
Which type of vaccine is capable of inducing a protective immune response by providing continuous antigenic stimulation over time?
Live attenuated vaccines
What distinguishes prophylactic vaccines from therapeutic vaccines?
Prophylactic vaccines prevent future infections, while therapeutic vaccines treat existing conditions
How are live attenuated vaccines typically prepared?
By growing the virus/bacteria in tissue cultures to select for less virulent strains

Subunit/fragment vaccines
What distinguishes subunit/fragment vaccines from live attenuated and inactivated killed vaccines?
Subunit/fragment vaccines contain only a part of the microorganism or its product
What is a characteristic of recombinant DNA (rDNA) vaccines?
They use genetic material from a pathogen to stimulate an immune response
What is an advantage of subunit/fragment vaccines over live attenuated and inactivated killed vaccines?
Reduced risk of causing the disease they protect against
