Berlin (dpa) - According to an analysis of the Barmer health insurance, there are larger implants in Germany. Among other things, the health insurance has checked billing data for around 45,700 school-freshmen who were insured with her in 2017.

Thereafter, no children were immunized enough for any important infectious disease such as measles, mumps or rubella, said the Barmer on Thursday at the presentation of their drug report. The vaccination rates were consistently below 90 percent, according to the box office. That was alarming, said Barmer CEO Christoph Straub. For a protective effect in society immunization rates of at least 95 percent are needed.

"Implants for toddlers in Germany are larger than previously known," summarized Daniel Grandt, co-author of the drug report and chief physician at the Hospital Saarbrücken. Thus, among the Barmer insured, more than every fifth child born in 2015 was not or only partially vaccinated against measles in the first two years of life. The vaccination rate - the proportion of children who had received the two measles vaccines - was only 78.9 percent. For six-year-old children born in 2011, measles vaccination coverage among Barmer insureds was 88.8 percent.

According to the official data of the school entrance examinations at the Robert Koch Institute (RKI), the vaccination rate for the first measles vaccine in 2017 was around 97 percent. The second measles vaccine was almost 93 percent. However, about nine percent of freshmen did not have a vaccination certificate.

The RKI had therefore already described in his methodology that the vaccination quotas given by him may be a bit too high, it was said on Thursday by the federal authority. If one were to regard all children without a vaccination certificate as unvaccinated, there would only be a vaccination rate of 81.4 percent with regard to measles protection at the beginning of school. The Barmer data with 88.8 percent would be between this worst assumption and the most favorable of almost 93 percent.

The RKI has also pointed to deficits in vaccination, it said. The evaluation of the Barmer was thorough. "With the data, however, only about eleven percent of the legally insured persons in Germany are depicted and it remains unclear how representative this insured clientele is for Germany," said the RKI.

The Barmer analysis shows the picture of the actual vaccination quotas, emphasize the authors of the study. In addition to measles, there are more Impflücken. Thus, among the Barmer insured in 2017, only 88.7 percent of six-year-olds were vaccinated against mumps and rubella. This is extremely worrying because children and adolescents would keep their implants in adulthood, said Straub.

The health insurance AOK or TK have such little surveys for their insured according to their own information not yet performed. However, there is the Impfsurveillance the Kassenärztlichen Association, which also works with billing data from legally insured. The latest data for 2014 indicate that the measles population in Germany has a vaccination rate of 73.9 percent for two-year-olds - albeit with large regional differences ranging from 68.9 percent in Baden-Württemberg to 80.5 percent in Hamburg.

The Barmer also looked at their insured, how many children in the first two years of life had received any of the 13 recommended vaccinations at all: That was 1855 children, who were born in 2015 - about three percent.

But the Barmer statistics also show a pleasing trend: in measles, the vaccination rates grew - from 73.8 in the year 2010 to 78.9 percent in the 2015 vintage. An increase was also observed by the Impfsurveillance of the Kassenärztliche Vereinigung. The latest data for 2014 show a nationwide rate of 73.9 percent, about three percentage points more than in 2010.

In mid-July, the federal cabinet initiated a measles vaccination law. As of March 2020, parents need to prove that they have been vaccinated before taking their children to a day care center or school. The Bundestag still has to agree.
