Age-related prevalence of cross-reactive antibodies against influenza A(H3N2) variant virus, Germany, 2003 to 2010.

To estimate susceptibility to the swine-origin influenza A(H3N2) variant virus (A(H3N2)v) in the German population, we investigated cross-reactive antibodies against this virus and factors associated with seroprotective titre using sera from representative health examination surveys of children and adolescents (n = 815, 2003­06) and adults (n = 600, 2008­10). Antibodies were assessed by haemagglutination inhibition assay (HI); in our study an HI titre ≥ 40 was defined as seroprotective. We investigated associated factors by multivariable logistic regression. Overall, 41% (95% confidence interval (CI): 37­45) of children and adolescents and 39% (95% CI: 34­44) of adults had seroprotective titres. The proportion of people with seroprotective titre was lowest among children younger than 10 years (15%; 95% CI: 7­30) and highest among adults aged 18 to 29 years (59%; 95% CI: 49­67). Prior influenza vaccination was associated with higher odds of having seroprotective titre (odds ratio (OR) for children and adolescents: 3.4; 95% CI: 1.8­6.5; OR for adults: 2.4; 95% CI: 1.7­3.4). Young children showed the highest and young adults the lowest susceptibility to the A(H3N2)v virus. Our results suggest that initial exposure to circulating seasonal influenza viruses may predict long-term cross-reactivity that may be enhanced by seasonal influenza vaccination.

[HPV vaccination coverage in German girls: results of the KiGGS study: first follow-up (KiGGS Wave 1)]. / Impfstatus und Determinanten der Impfung gegen humane Papillomviren (HPV) bei Mädchen in Deutschland : Ergebnisse der KiGGS-Studie - Erste Folgebefragung (KiGGS Welle 1).

OBJECTIVES: In Germany, vaccination against HPV infection has been recommended for girls aged 12-17 years since 2007. The aim of this paper was to provide an overview of the current status and determinants of HPV vaccination uptake in Germany. METHODS: Analyses included data from 14- to 17-year-old girls (n =1,337) of the German Health Interview and Examination Survey for Children and Adolescents - First Follow-up Survey (KiGGS Wave 1). Standardized telephone interviews included questions for girls on the number of HPV vaccine doses and visits to a gynecologist. Parents were asked about their socioeconomic status (SES) and the girls' participation in the J1 adolescent health check-up. Descriptive analyses of the HPV vaccination status with respect to social, demographic, and health-care utilization factors were performed. Factors associated with vaccination were identified and odds ratios (OR) were estimated by means of logistic regression analysis. RESULTS: The prevalence of vaccination with at least one HPV vaccine dose was 52.6% (95% confidence interval 48.5-56.6). Three-dose HPV vaccination coverage was 39.5% (35.3-43.9). Vaccine uptake increased with age, was higher in girls with middle and low SES compared with high SES, with residence in eastern Germany, in those who had already seen a gynecologist, and who participated in the J1. Multivariable logistic regression revealed a twofold increased chance of being vaccinated for girls with middle SES (OR 1.9) compared with high-SES girls and for those who had yet seen a gynecologist (OR 2.1). CONCLUSIONS: School-based vaccination programs and multi-tier vaccination campaigns have led to high vaccination rates in some European and non-European countries. In Germany, however, such high vaccination rates have not been achieved. To fully realize the potential of HPV vaccinations to reduce HPV-related cancer incidence at the population level, vaccination coverage in Germany must be increased. In absence of school-based vaccination programs, medical doctors should use each visit to check and complete the girl's vaccination status.

[Chronic and vaccine-preventable diseases in children and adolescents in Germany: results of the KiGGS study: first follow up (KiGGS wave 1)]. / Chronische Erkrankungen und impfpräventable Infektionserkrankungen bei Kindern und Jugendlichen in Deutschland : Ergebnisse der KiGGS-Studie - Erste Folgebefragung (KiGGS Welle 1).

The German Health Interview and Examination Survey for Children and Adolescents (KiGGS) 2003-2006 is the first nationwide comprehensive study on the health of children and adolescents living in Germany. The KiGGS first interview follow-up is a telephone interview study that collected, among other things, data on a number of chronic and vaccine-preventable diseases in 2009-2012 and is a combined cross-sectional and longitudinal study based on a population registry sample from the 167 KiGGS study points. The analysis is based on 12,368 respondents (7913 KiGGS follow-up participants aged 7-17 years, response 72 % and 4455 newly recruited 0- to 6-year-olds, response 42 %). Based on parent reports the lifetime prevalence of both chickenpox and pertussis has decreased in the population targeted by recently changed vaccination recommendations. For measles the prevalence remained unsatisfactorily high in each investigated age group. Of the children and adolescents aged 0-17 years 16 % (95 % confidence interval CI 15.2-17.0 %) had a long-standing chronic health condition according to the parents. Of these, however, only one in five was affected in their routine daily activities. The lifetime prevalence in 7- to 17-year-olds was 1.2 % (0.9-1.6) for epilepsy (0.4 % for the past 12 months), 5.0 % (4.4-5.7) for migraine, 0.2 % (0.1-0.3) for diabetes and in 0 to 6-year-olds 2.0 % (1.5-2.6) for heart conditions and 3.1 % (2.5-3.8) for febrile seizures with a -prevalence in 0 to 2-year-olds which are most affected of 1.0 % (0.6-1.6) in the past 12 months. The vast majority of children and adolescents in Germany are in good or very good health as suggested by other results reported in this issue; however, chronic conditions are not rare and need continuous monitoring. These results confirm that implementation of the vaccination recommendations of the German Standing Committee on Vaccination (STIKO) can lead to effective prevention of infectious diseases in Germany.

[Unintentional injuries in childhood and adolescence: current prevalence, determinants, and trends: results of the KiGGS study: first follow-up (KiGGS Wave 1)]. / Das Unfallgeschehen im Kindes- und Jugendalter - Aktuelle Prävalenzen, Determinanten und Zeitvergleich : Ergebnisse der KiGGS-Studie - Erste Folgebefragung (KiGGS Welle 1).

BACKGROUND: In Germany and worldwide, unintentional injuries (UI) are a major health threat for children and adolescents. The first follow-up of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 1, 2009-2012) continued the national UI monitoring that started with the KiGGS baseline study (2003-2006). The present analysis provides updated information and for the first time gives indications on time trends. METHODS: KiGGS Wave 1 is a combined nationwide cross-sectional and longitudinal survey by the Robert Koch Institute (RKI) providing information about 12,368 participating children and adolescents (0-17 years old; response rates: 38.8% first time invited, 72.9% reinvited). Parents were asked about their children's UI and poisonings via telephone interviews. Information on UI is available for 11,665 children and adolescents (1-17 years old). The 12-month prevalence rate and 95% confidence interval were calculated, and KiGGS Wave 1 was compared with the KiGGS baseline study. The Rao-Scott chi-square test corrected over the F distribution was used to test for the statistical significance of subgroup differences and trend effects. RESULTS: Within the previous 12 months, 15.5% of all children and adolescents aged 1-17 years were medically treated for UI. UI were significantly more prevalent among boys (17.0%) than among girls (14.0%), and 3.4% of the subjects had more than one accident leading to UI. One in eight children and adolescents who suffered UI stayed in hospital (12.3%) for inpatient treatment for at least one night. The home, childcare and educational institutions, and sports facilities/playgrounds were the predominant accident locations. Compared to the baseline study, neither the overall prevalence of UI nor the gender- and age-specific patterns changed significantly. CONCLUSION: Since a large proportion of UI is avoidable, knowledge of high-risk subgroups and accident locations is of particular use for prevention. KiGGS Wave 1 makes an important contribution to the comprehension of these issues. The transfer of research into practice is of particular importance for the avoidance of UI.

[Factors influencing the prevalence and duration of breastfeeding in Germany: results of the KiGGS study: first follow up (KiGGS Wave 1)]. / Einflussfaktoren auf Verbreitung und Dauer des Stillens in Deutschland : Ergebnisse der KiGGS-Studie - Erste Folgebefragung (KiGGS Welle 1).

Breastfeeding is the natural way of feeding infants in the first months of their lives and has been proven to have health benefits for both infants and mothers. Breastfeeding initiation and duration are affected by social, demographic and health factors. The aim of this study was to describe the current rates of breastfeeding initiation and duration in Germany, and to identify potential factors that underline these rates. Additionally, results are compared with the KiGGS basic (2003-2006; birth cohorts 1996-2002) study in order to reveal the development in the trends of breastfeeding initiation and duration in Germany. The KiGGS wave 1 (2009-2012) includes data on the breastfeeding behavior of mothers of 4410 children aged between 0 and 6 years (birth cohorts 2002-2012). Altogether, 82% (95% confidence interval 79.8-84.2 %) of children were ever breastfed, and the average breastfeeding duration was 7.5 months (7.2-7.8). There was a slight increase in the breastfeeding initiation in Germany over the last several years. Breastfeeding initiation among children aged 0-6 years increased by 4% points compared to 0- to 6-year-olds (birth cohorts 1996-2002) from the KiGGS basic study. The breastfeeding duration stayed unchanged. The breastfeeding behavior was mainly related to the age of the mother at birth, the mother's education level, smoking during pregnancy, and multiple or premature birth. Despite the overall increasing trend in breastfeeding initiation, there is still a growing need for breastfeeding promotion and support for young and less educated mothers, mothers who smoke during pregnancy, and also for mothers with premature babies or multiple births.

[Physical activity and electronic media use in children and adolescents: results of the KiGGS study: first follow-up (KiGGS wave 1)]. / Körperlich-sportliche Aktivität und Nutzung elektronischer Medien im Kindes- und Jugendalter : Ergebnisse der KiGGS-Studie - Erste Folgebefragung (KiGGS Welle 1).

Physical activity during childhood and adolescence has numerous health benefits, while sedentary behavior, especially electronic media use, is associated with the development of overweight. Therefore, the promotion of physical activity during childhood and adolescence is an integral part of national public health efforts. The aim of this article is to describe the physical activity behavior of German children and adolescents based on the nationwide data of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS wave 1). Furthermore, the association between physical activity and sports participation and use of screen-based media in youth aged 11 to 17 years was analyzed. The analyses included data from 10,426 children and adolescents aged 3-17 years collected by telephone interviews. Children older than 11 years answered the questions by themselves, whereas a parent was interviewed for younger children. The descriptive analyses were performed under consideration of social and demographic factors. According to the results of KiGGS wave 1 a total of 77.5% (95% Cl 76.0-78.9 %) of the children and adolescents participated in sports activities, and 59.7% (58.1-61.3 %) were members of a sports club. The recommendation of the World Health Organization (WHO) to be physically active at least 60 min per day was achieved by 27.5% (26.0-28.9 %). Children and adolescents with a low socioeconomic status (SES) participated less in sports activities than children of higher SES groups. Excessive use of screen-based media was more likely to be associated with lack of sports participation than with a lack of physical activity. In the future, preventive measures should promote the daily physical activity of children and adolescents and additionally encourage children and adolescents with low SES to participate in sports activities.

[Vaccination coverage in German adults: results of the German Health Interview and Examination Survey for Adults (DEGS1)]. / Impfstatus von Erwachsenen in Deutschland: Ergebnisse der Studie zur Gesundheit Erwachsener in Deutschland (DEGS1).

In the absence of an immunisation register, vaccination coverage in Germany must be estimated. Ten years after the German National Health Interview and Examination Survey 1998 (GNHIES98), the population survey DEGS1 is one of the data sources to be used for monitoring vaccination coverage. In the survey, data on vaccination history were obtained from vaccination cards and self-reports. The prevalence of immunisation for tetanus and diphtheria was higher compared to the prevalence estimated ten years previously in GNHIES98. Nonetheless, 28.6 % of adults have not been vaccinated against tetanus and 42.9 % have not been vaccinated against diphtheria within the last ten years. Vaccination is especially low among the elderly, among adults with low socio-economic status and in western Germany. During the last ten years, only 11.8 % of women and 9.4 % of men were vaccinated against pertussis in western Germany; vaccination coverage was twice as high in eastern Germany. In 2009, recommendations were published to combine the next tetanus immunisation with a pertussis immunisation; therefore pertussis vaccination coverage might improve in the coming years. The lifetime prevalence of influenza vaccination obtained in DEGS1 is higher than the annual vaccination rate for influenza. However, the lifetime prevalence among adults aged 60 years or older is still below the annual rate of 75 % recommended by the WHO.

[Vaccination coverage against measles and sero-epidemiology of measles-specific IgG antibodies in German children and adolescents]. / Durchimpfung und Prävalenz von IgG-Antikörpern gegen Masern bei Kindern und Jugendlichen in Deutschland.

BACKGROUND: Measles is a vaccine-preventable disease that could be eliminated by global vaccination strategies with two-dose measles vaccination. The World Health Organization (WHO) European Region aims at achieving measles elimination by 2015. Target control is mainly based on verification of 95 % vaccination coverage. In Germany, target verification cannot be based on data from centrally collected registers on vaccination and seroprevalence of measles-specific antibodies. OBJECTIVE: This paper provides an overview of measles vaccination coverage and the timeliness of measles vaccination in birth cohorts 1989-2008. In addition, factors associated with vaccination gaps are described. METHODS: Primary data on vaccination coverage (annual school entrance health examination) and on vaccination coverage and immune status (population-based German Health Interview and Examination Survey for Children and Adolescents - KiGGS) and secondary data (insurance refund claim data) are described and discussed. RESULTS AND CONCLUSION: The measles immunization coverage (two doses) obtained in the 2010 school entrance examinations was 91.5 %. The range was 87.6-95.3 % between Federal States. Regional differences were even more pronounced between districts. The timeliness of the two-dose measles immunization increased from 41 % (birth cohorts 2001/2002) to 66 % (birth cohorts 2006/2008). Despite progress in recent years, measles vaccination coverage is still inadequate in adolescents, young adults, and young children. The German Standing Committee on Vaccination (STIKO) recommends a combined MMR vaccination of adults who were born after 1970 and who were not fully vaccinated against measles during childhood. Successful implementation of this recommendation is crucial just as it is important to step up efforts to improve the timeliness of measles vaccination in young children. Regional vaccination gaps and susceptible clusters defined by age or sociodemographic parameters are of particular importance to the epidemiology of measles disease. Knowledge of the factors associated with nonimmunization should be used to tailor vaccination strategies.

[Epidemiology of hepatitis A, B, and C among adults in Germany: results of the German Health Interview and Examination Survey for Adults (DEGS1)]. / Die Seroepidemiologie der Hepatitis A, B und C in Deutschland: Ergebnisse der Studie zur Gesundheit Erwachsener in Deutschland (DEGS1).

Ten years after seroepidemiological data were obtained in the German National Health Interview and Examination Survey 1998 (GNHIES98), German Health Interview and Examination Survey (DEGS1) data contribute to a population-based, representative surveillance of hepatitis A and B immunity and of the serological markers for hepatitis C in Germany. The prevalence of antibodies against the hepatitis A virus is 48.6 %. In comparison to the situation 10 years ago, seroprevalence is significantly higher among 18- to 39-year-old adults and is significantly lower in those aged 50-79 years. The association between age and seroprevalence has changed, indicating a decrease in naturally acquired hepatitis A immunity. Individual and population immunity has to be achieved through vaccination. Prevalence of hepatitis B antibodies indicates that 5.1 % of adults have been exposed to the virus, significantly fewer than 10 years ago (7.9 %). Prevalence of hepatitis B surface antibodies indicates that 22.9 % of adults have been vaccinated against hepatitis B. Vaccination coverage has increased in all age groups and is highest in the younger age groups. These positive trends can be attributed to the general recommendation since 1995 to vaccinate against hepatitis B. For hepatitis C, the prevalence of antibodies in the general population is 0.3 %. Germany thus remains a low-HCV-endemic country. An English full-text version of this article is available at SpringerLink as supplemental.

Estimating vaccination coverage in the absence of immunisation registers--the German experience.

Immunisation registers are regarded as an appropriate solution to measure vaccination coverage on a population level. In Germany, a decentralised healthcare system and data protection regulations constrain such an approach. Moreover, shared responsibilities in the process of immunisation and multiple providers form the framework for public health interventions on vaccination issues. On the national level, those interventions consist mainly of conceptualising immunisation strategies, establishing vaccination programmes, and issuing recommendations. This paper provides an overview on sources and methods for collecting appropriate coverage data at national level and their public health relevance in Germany. Methods of data collection and available information on immunisations are described for three approaches: school entrance health examination, population surveys and insurance refund claim data. School entrance health examinations allow regional comparisons and estimation of trends for a specific cohort of children and for all recommended childhood vaccinations. Surveys deliver population based data on completeness and timeliness of selected vaccinations in populations defined by age or socio-demographic parameters and on knowledge and attitudes towards vaccination. Insurance refund claim data inform continuously on immunisation status (e.g. of children aged two years) or on vaccination incidence promptly after new or modified recommendations. In a complex healthcare system, the German National Public Health Institute (Robert Koch Institute, RKI) successfully compiles coverage data from different sources, which complement and validate one another. With the German approach of combining different data sources in the absence of immunisation registers, it is possible to gain solid and reliable data on the acceptance of vaccination programmes and target groups for immunisation. This approach might be of value for other countries with decentralised healthcare systems.

[Relationship between physical activity and health in children and adolescents. Results of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) and the "Motorik-Modul" (MoMo)]. / Zum Zusammenhang zwischen körperlicher Aktivität und Gesundheit bei Kindern und Jugendlichen. Ergebnisse des Kinder- und Jugendgesundheitssurveys (KiGGS) und des Motorik-Moduls (MoMo).

The question of whether physical activity is associated with positive aspects of health becomes increasingly more important in the light of the health status in today's children and adolescents and due to the changing lifestyle with respect to everyday activity. The German Health Interview and Examination Survey for Children and Adolescents (KiGGS) collected the first set of nationwide representative cross-sectional data to examine the relationship between health and physical activity. Taking sociodemographic parameters into consideration, the results suggest a positive association between self-estimated general health and several types of physical activity. The results vary with respect to gender and type of physical activity. For methodological reasons, causal conclusions can only be drawn after longitudinal data of the second wave of KiGGS are available.

[Suspected adverse reactions after vaccination. Results from the German Health Interview and Examination Survey for Children and Adolescents. Part I: descriptive analyses]. / Impfnebenwirkungen bei Kindern und Jugendlichen. Ergebnisse des Kinder- und Jugendgesundheitssurveys. Teil 1: Deskriptive Analysen.

The decreasing incidence of vaccine-preventable infectious diseases and their complications redirects public attention to the safety risks of vaccinations. Collation of resilient vaccine adverse reaction data from passive and active surveillance systems as well as epidemiological studies is indispensable. From 2003-2006, the representative National Health Interview and Examination Survey for Children and Adolescents ("Kinder- und Jugendgesundheitssurvey," KiGGS) retrospectively collected information about vaccines, vaccination dates, and suspected vaccine-related adverse events. A total of 15,958 participants (<17 years of age) were included in the analyses. Parents of 332 (2.1%; 95% CI 1.8-2.5) children and adolescents reported that one or more vaccinations were poorly tolerated. The reported adverse reactions were largely in accordance with information given in the summaries of product characteristics of the respective vaccines. Calculated rates of adverse reactions were below the known rates. KiGGS allowed the retrospective collection of suspected adverse reactions from a large number of vaccinations, thereby providing data even on rare adverse events. No unusual pattern was observed. The information obtained on suspected adverse reactions does not change the positive benefit-risk ratio of vaccinations.

[Suspected adverse reactions after vaccination. Results from the German Health Interview and Examination Survey for Children and Adolescents. Part 2: predictors of parental reporting of suspected adverse reactions after vaccinations]. / Impfnebenwirkungen bei Kindern und Jugendlichen. Ergebnisse des Kinder- und Jugendgesundheitssurveys. Teil 2: Einflussfaktoren auf elterliche Berichte über Impfnebenwirkungen.

Each method to monitor vaccine safety has strengths and limitations. Therefore, vaccine safety monitoring should rely on different types of data sources. Methods commonly rely on patient-reported adverse reactions. Little is, however, known about factors that may affect the probability with which patients report adverse reactions to vaccines. From 2003-2006, the representative National Health Interview and Examination Survey for Children and Adolescents ("Kinder- und Jugendgesundheitssurvey", KiGGS) retrospectively collected information about vaccines, vaccination dates, and suspected vaccine related adverse reactions from a total of 17,641 participants (<17 years). Poorly tolerated vaccinations were more likely reported from parents living in former West Germany compared to former East Germany (OR 1.61; 95% CI 1.08-2.39), parents of children with special health care needs (OR 1.49; 95% CI 1.08-2.04), and from parents reporting reservations against vaccinations (OR 3.29; 95% CI 2.28-4.75). Parental reporting of adverse vaccine reactions appears to be associated with parental perception and assessment of possible adverse vaccine reactions, as well as with the parents' attitude towards immunization in general.

Low hepatitis B immunogenicity of a hexavalent vaccine widely used in Germany: results of the German Health Survey for Children and Adolescents, 2003-2006.

The success of childhood vaccination against hepatitis B relies on persistence of immunity into adolescence and adulthood. In 2000, two hexavalent vaccines with a hepatitis B component (Hexavac, Infanrix hexa) were introduced in Germany. Hexavac was withdrawn in 2005 amidst concerns about its long-term hepatitis B protection. We compared hepatitis B surface antibody (anti-HBs) levels in children fully vaccinated with Hexavac or Infanrix hexa (n=477) in a secondary data analysis of a large cross-sectional health survey in Germany. On average 2.4 years after vaccination, 25.3% of Hexavac vaccinees had anti-HBs levels <10 mIU/ml (95% CI 19.0-32.8) compared to 4.7% of Infanrix hexa vaccinees (95% CI 2.4-8.9). These findings suggest that short-term hepatitis B immunogenicity in Hexavac vaccinees may also be weaker. Further studies are warranted to assess whether Hexavac vaccinees should be re-vaccinated or receive a booster vaccination before these birth cohorts reach adolescence.

[Current vaccination coverage and immunization gaps of children and adolescents in Germany]. / Aktuelle Entwicklung von Impfquoten und Impflücken bei Kindern und Jugendlichen in Deutschland.

Available data show increasing vaccination coverage of children and adolescents in recent years in Germany. Vaccination coverage of children against diphtheria, tetanus, polio and haemophilus influenzae Type b is high. Vaccination gaps exist for pertussis, hepatitis B and for the second measles, mumps and rubella doses. Coverage is still insufficient to achieve effective herd immunity and measles elimination. Data from the representative German Health Interview and Examination Survey for Children and Adolescents reveal that vaccination of infants is markedly delayed compared to recommendations of the German Standing Committee on Vaccination (STIKO). Particularly older children and adolescents are often not fully vaccinated or are even unvaccinated. A high proportion is missing the recommended booster doses against diphtheria, tetanus, pertussis and polio. Vaccination compliance especially regarding completeness and timeliness is lower in western than eastern Germany, as well as in children of vaccine sceptics and foreign-born children. More comprehensive surveillance of vaccination coverage and adverse events following immunization as well as the implementation of a national immunization plan focussing on closure of immunization gaps could lead to improved vaccination coverage.

When are bioavailability studies required? A German proposal.

The Bundesinstitut für Arzneimittel und Medizinprodukte (BfArM), the German drug regulation authority, issued guidelines for determining whether bioavailability/bioequivalence studies are required for certain drugs. This decision tree is based on pharmacodynamic, pharmacokinetic, and physicochemical criteria. Details of this decision tree were worked out by an expert panel, the Bioavailability Commission at the BfArM. The decision tree has been in use by German regulatory authorities for more than 10 years. In the meantime, its essentials were adopted by the European Committee for Proprietary Medicinal Products (CPMP) and by the World Health Organization (WHO) for their "Guidelines on interchangeability of multisource pharmaceutical products." This article reviews the original decision tree of the BfArM and provides examples of drugs that have been assessed according to its rules. The current procedure of the German regulatory authorities for judging the necessity of bioavailability trials, which reflects the status quo of regulatory practice in Germany, is also discussed.

[Vaccination coverage and predictors for vaccination level. Results of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS)]. / Durchimpfung und Determinanten des Impfstatus in Deutschland. Ergebnisse des Kinder- und Jugendgesundheitssurveys (KiGGS).

The level of childhood immunisation is an acknowledged indicator for health prevention. In Germany, vaccination is not compulsive. Continuous representative data derive only from school health examinations. From May 2003 until May 2006 the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) was conducted and vaccination information on 16,460 participants was obtained. Using data on the vaccination cards, it was possible to make detailed analyses of vaccination coverage in children up to the age of 17. Different vaccine types were taken into consideration in defining the term 'immunisation coverage'. The average prevalence of full immunisation for tetanus, diphtheria und polio as well as the coverage for the first dose of measles, mumps and rubella (MMR) vaccination was above 90% in children aged 2-17 years. Vaccination coverage for pertussis, Hib and hepatitis B is higher in younger than in older age groups. Compliance with the recommendation to have a second MMR dose and to make up of hepatitis B and pertussis immunisation is still low, especially in adolescents. In 7- to 17-year-old children the additional booster (recommended for 5- to 6-year-old children) is frequently missing.
