Question

Quizplus · Accepted Answer

Genetic manipulation to remove virulence factors results in an attenuated vaccine, which means that the microbe is weakened or less virulent but still able to elicit an immune response. Inactivated vaccines are produced by killing the microbe with chemicals or heat, while toxoid vaccines are made by modifying bacterial toxins to make them harmless. Combination vaccines contain multiple antigens from different microorganisms, and DNA vaccines use genetic material to stimulate an immune response.
