The draft law stipulates that all children from the age of one must have the measles vaccinations recommended by the Standing Vaccination Commission when entering school or a daycare facility. Proof of measles vaccination must also generally be provided if the child is cared for by a childminder.

The same applies to people who work in community facilities (daycare centers) or medical facilities, such as educators, teachers, daycare workers and medical staff (if they were born after 1970).

Proof can be provided by the vaccination card, the yellow child examination booklet or - especially in the case of illness already suffered - a medical certificate. As a rule, proof must be provided to the management of the facility. Children who are already being cared for in kindergarten and school or in other community facilities must provide proof by December 31, 2021. It is also possible to provide confirmation from a previously attended facility that corresponding proof has already been provided there.

The same applies to staff in communal facilities (childcare facilities) and medical facilities, such as hospitals or doctors' surgeries. This is already common practice in medical facilities. Here, too, staff must prove that they have been vaccinated, have already had the disease and are therefore immune.

If the parents do not provide written proof of the child's sufficient vaccination protection when they are first admitted to a KiTa, the daycare center management must inform the responsible health authority in accordance with § 12 KiBiz.

On 07.07.2017, the Bundestag passed the "Act on the Modernization of Epidemiological Surveillance of Communicable Diseases", which came into force on 25.07.2017. The law contains an amendment to Section 34 (10a) of the Infection Protection Act (IfSG). This paragraph previously stipulated that health authorities could invite parents to a vaccination consultation if they could not provide proof of a vaccination consultation when they were first admitted to a childcare facility. In North Rhine-Westphalia, the obligation to provide proof of an age-appropriate preventive health check is set out in Section 12 KiBiz.

This regulation has been amended to the extent that daycare center managers must now inform the responsible health authority of any failure to provide proof of vaccination consultation and transmit the personal data to the health authority. The health authority then decides whether the parents or guardians should be invited to a vaccination consultation.

Legislative wording (Section 34 (10a) IfSG new version)

"Upon initial admission to a child daycare facility, the legal guardians must provide the facility with written proof that the child has received medical advice regarding complete, age-appropriate vaccination protection that is sufficient according to the recommendations of the Standing Vaccination Commission in a timely manner prior to admission. If proof is not provided, the management of the childcare facility will notify the public health department in whose district the facility is located and provide the public health department with personal details. The public health department may invite the legal guardians to a consultation. Further state regulations remain unaffected."
