Increased carriage of non-vaccine serotypes with low invasive disease potential four years after switching to the 10-valent pneumococcal conjugate vaccine in The Netherlands - Fig 4

<p><b>Serotype distribution of IPD in children (<5 years) (A) and older adults (>65 years) (B).</b> Incidence of IPD was calculated per two epidemiological years. The first bar (June 2004- June 2006) depicts the IPD incidence in the years before implementation of PCV. The following five bars depict IPD incidence as observed after introduction of pneumococcal vaccination; respectively 1 year after PCV7 implementation (June 2006 –June 2008), 3 years after PCV7 implementation (June 2008 –June 2010), 5 years after PCV7 implementation (June 2010 –June 2012), 2 years after PHiD-CV10 implementation (June 2012 –June 2014) and 4 years after PHiD-CV10 implementation (June 2014 –June 2016).
