  1. Impact of alternative parameter values on the total number of cases of invasive pneumococcal disease (all ages) caused by vaccine and non-vaccine serotypes (VT and NVT respectively) and predicted by the model in the 20 years following PCV7 introduction under Strategy 1 in England and Wales. Base case parameter values are reported in bold.
