Question

Live, attenuated vaccines Select one:

a. include the Sabin polio vaccine.
b. include the measles, mumps, rubella vaccine (MMR).
c. contain viable microbes that can multiply in the person.
d. require smaller doses and fewer boosters compared to inactivated vaccines.
e. All of the choices are correct.

Answer 1

Live, attenuated vaccines include the Sabin polio vaccine and the measles, mumps, rubella vaccine (MMR). They contain viable microbes that can multiply in the person and require smaller doses and fewer boosters compared to inactivated vaccines.

Step-by-step explanation:

Live, attenuated vaccines are vaccines that contain weakened or attenuated forms of pathogens. These vaccines include the Sabin polio vaccine and the measles, mumps, rubella vaccine (MMR). They contain viable microbes that can multiply in the person, stimulating a comprehensive immune response. Live, attenuated vaccines generally require smaller doses and fewer boosters compared to inactivated vaccines.

Answer 2

All of the choices are correct in case of live, attenuated vaccines.

Option: (e)

Step-by-step explanation:

• Attenuated vaccine is created by live pathogens whose virulence is reduced or even removed.

• Pathogens are attenuated by passing them through a foreign host such as tissue culture, embryonated eggs, live animals etc.

• Immuno compromised individuals cannot use this type of vaccine. If secondary mutation happens reversion to virulence can occur.

• In comparison to inactivated vaccine, the cost is low and provides quick immunity against various diseases.
