VMC-0092
QUESTION
The vaccine which has the risk of residual virulence is?
OPTIONS
(A) Live virus vaccine
(B) Peptide vaccine
(C) Recombinant vaccine
(D) Subunit vaccine
ANSWER
(A) Live virus vaccine
EXPLANATION
Live virus vaccines contain viable attenuated organisms and therefore carry a theoretical risk of residual or insufficiently attenuated virulence. Thus option A is correct; peptide, recombinant, and subunit vaccines are non-replicating vaccine platforms and do not carry the same residual-virulence risk.
