Pneumococcal Conjugate Vaccines (PCV)

PCV prevents pneumococcal disease caused by Streptococcus pneumoniae, which can lead to severe infections like pneumonia, meningitis, and sepsis (Statement 1 is correct). By preventing infections, vaccines reduce the need for antibiotics, thereby combatting the rise of Anti-Microbial Resistance (AMR) (Statement 2 is correct). Statement 3 represents an extreme generalization; no vaccine is entirely devoid of side effects (like mild fever or injection site pain) or the potential for rare allergic reactions (Statement 3 is incorrect). > One-line conceptual takeaway: Vaccines provide the dual benefit of preventing deadly diseases and curbing the reliance on antibiotics, fighting AMR. Answer: (a).
