Prevnar protects against infection by which organism?

Prevnar protects against infection by which organism?

• A. Streptococcus pneumoniae
• B. Haemophilus influenzae type b
• C. Neisseria meningitidis
• D. Varicella zoster

Answer: (A)

Prevnar is a pneumococcal conjugate vaccine designed to protect against infections caused by Streptococcus pneumoniae. It contains capsular polysaccharide antigens from multiple pneumococcal serotypes linked to a protein carrier, which boosts the immune response in children. By targeting these serotypes, Prevnar reduces the risk of diseases caused by S. pneumoniae, such as pneumonia, meningitis, bacteremia, and otitis media. It does not protect against Haemophilus influenzae type b, Neisseria meningitidis, or Varicella zoster, which are addressed by their own vaccines.
