BACKGROUND: Invasive pneumococcal disease (IPD) is caused by Streptococcus pneumoniae and mostly presents as pneumonia, sepsis or meningitis. A notable portion of IPD cases is vaccine preventable and the pneumococcal conjugate vaccine (PCV) was introduced into the routine childhood immunization programs in many countries during the last decades. OBJECTIVES: Before PCV introduction in the Czech Republic in 2010, a national surveillance system for IPD was implemented in 2008 and further improved in 2011. In this study, we describe the new surveillance system for the first time and measure its sensitivity between 2010 and 2013 using the capture-recapture method. Furthermore, we describe the recent epidemiological trend of IPD, taking sensitivity estimates into account. RESULTS AND CONCLUSIONS: Between 2010 and 2013 the estimated sensitivity of the overall IPD surveillance increased from 81% to 99%. The sensitivity of individual reporting sources increased from 72% to 87% for the laboratory system and from 31% to 89% for the epidemiological notification system. Crucial for this improvement was the introduction of quarterly report reminders in 2011. Due to positive source dependency, the presented sensitivity estimates are most probably overestimated and reflect the upper limit of reporting completeness. Stratification showed variation in sensitivity of reporting particularly according to region. An effect of the PVC vaccination in the Czech Republic is visible in the incidence of IPD in target age groups (<5 y). This influence was not evident in the total IPD incidence and may interfere with increasing sensitivity of reporting. In 2013, an increase in the IPD incidence was observed. This finding requires further observation and a detailed vaccine impact analysis is needed to assess the current immunization strategy.

Hygienická stanice hlavního města Prahy zjišťovala při kontrole proočkovanosti v jarním období roku 2012 v ordinacích praktických lékařů pro děti a dorost též počty kalmetizovaných dětí, indikace ke kalmetizaci a důvody neprovedení kalmetizace u dětí narozených v období 1. 1. 2011 až 31. 12. 2011. Kontrola proočkovanosti byla též provedena ve všech pražských kalmetizačních centrech. Indikaci ke kalmetizaci mělo 7,6 % dětí, do 6. týdne věku však byly očkovány jen asi 2/3 indikovaných dětí. Častým důvodem neočkování byl výpadek očkovací látky, který nastal v ČR. Na žádost rodičů bylo očkováno 0,6 % dětí narozených v roce 2011. Neefektivní revakcinace byla v Praze i v roce 2011 běžně prováděna.

When checking the BCG vaccination coverage in GPP surgeries in spring 2012, the Public Health Authority of the City of Prague was also looking into the numbers of BCG vaccinated children, indications for BCG and the reasons for non-vaccination in children born in the time range of 1st January 2011 – 31st December 2011. BCG vaccination coverage was also being evaluated in all of Prague's BCG vaccination centres. 7.6 % of the examined children were indicated for BCG vaccination but only about 2/3 of the indicated children were vaccinated before the end of their 6th week. A common reason for non-vaccination was shortage of the vaccine, which occurred in Czech Republic at the time. 0.6 % of the children born in 2011 were vaccinated at the request of their parents. Inefficient revaccinations were still routinely conducted in Prague in 2011.
