In recent Analysis article,1 the second figure illustrating the cases of invasive pneunomoccocal infection among adults 65 years and older was incorrect. The correct figure, Fig. 1, is included here.

Cases of invasive pneumococcal infection per 100 000 among adults 65 years and older according to year and serotype group. Data from CASPER Surveillance, 1998–2004 (c2 or Fisher exact test for comparisons). When compared with the combined rate between 1998 and 2001, the rate in 2004 decreased by 62.7% to 8.5 (95% CI 3.7–16.7) for PCV7 serotypes (p = 0.007); the change of 23.9% to 28.6 (95% CI 18.9–41.7) for all serotypes was not significant (p = 0.24), nor was the change of 24.1% to 8.5 (95% CI 3.7–16.7) for PPV23 serotypes that are not in PCV7 (p = 0.59). The increase of 163.9% to 9.5 (95% CI 4.4–18.1) for nonPPV23 serotypes was significant (p = 0.03).
