What is the purpose of an inactivated polysaccharide vaccine?

• A. To stimulate an immune response without live pathogens
• B. To provide long-lasting immunity through live viruses
• C. To alter host DNA for immune protection
• D. To replicate from a weakened strain of a virus

Answer: (A)

An inactivated polysaccharide vaccine is designed to stimulate an immune response without using live pathogens. This approach allows the body to recognize and respond to the polysaccharide components of the bacteria or virus, triggering the immune system to create antibodies. By using inactivated components, the risk of causing disease in the vaccinated individual is eliminated, making it a safer option compared to live attenuated vaccines. Inactivated polysaccharide vaccines focus on generating an immune response through the polysaccharide capsule of bacteria, as these vaccines help the body to recognize and respond to future infections. They do not alter the host's DNA or rely on weakened strains to generate immunity, which is characteristic of other types of vaccines. Thus, the primary function is to provide effective immunity through the stimulation of an immune response without the risk associated with live pathogens.
