The presentation has also remained unchanged over this period, with around 60\% of cases presenting as meningitis{\textpm}sepsis, 20\% cases presenting as sepsis{\textpm}pneumonia and 20\% presenting as isolated pneumonia.Conclusions The seven valent pneumococcal vaccine (PCV7), which covers serotypes 4, 6B, 9V, 14, 18C, 19F and 23F, was introduced in September 2006. The authors{\textquoteright} findings suggest that despite good uptake of this vaccine, there has been no decrease in the number of cases of IPD admitted to UK PICUs. These findings are consistent with data from the Health Protection Agency,1 which demonstrate that although vaccine serotypes have been almost eradicated since vaccination, there has been no change in the total number of cases of IPD. This is due to serotype replacement with non-vaccine serotypes. IPD is still an important cause of critical illness in children despite the pneumococcal vaccination programme.}, issn = {0003-9888}, URL = {https://adc.bmj.com/content/95/Suppl_1/A1.3}, eprint = {https://adc.bmj.com/content/95/Suppl_1/A1.3.full.pdf}, journal = {Archives of Disease in Childhood} }
