Table 3.
The incidence of invasive pneumococcal disease (IPD) pre- and 10 years post-vaccination. The table presents the posterior predictive mean values with the 95% predictive intervals.
| Age group (years) | Pre-vaccination IPD incidence (/100,000/year) |
10 years post-vaccination IPD incidence (/100,000/year) |
