In reply: We agree with Collignon that pneumococcal conjugate vaccines (PCVs) are superior to polysaccharide pneumococcal vaccines (PPVs), and that the herd immunity impact of the PCV on older people is impressive. However, we do not agree that our study shows that the PPV is ineffective in older people, or that its use has resulted in an increase in disease.
