Answer 1

ANSWER:

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

Option: (e)

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.
