Fig. 3From: Assessing the efficiency of catch-up campaigns for the introduction of pneumococcal conjugate vaccine: a modelling study based on data from PCV10 introduction in Kilifi, KenyaThe predicted number of IPD cases averted by PCV10 vaccination in Kilifi with respect to the number of doses administered. In the dose-efficacy plane (a) the aggregated dose efficiency of the alternative introduction strategies within 10 years after the start of vaccination is shown. Coloured dots and lines represent medians and 95% credible intervals (the number of doses administered is fixed as taken from the health register). b shows the (incremental) number of doses needed to prevent one (additional) case of IPD. Figures for cohort vaccination alone and cohort vaccination in year 10 are presented as absolute values; the catch-up scenarios are presented as incremental values over the next smaller campaignBack to article page
