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.
