[Is complete immunity against measles a realistic target for patients with rheumatic diseases and how can it possibly...

Measles outbreaks occur rather frequently in Germany. Patients with chronic inflammatory diseases are often treated with immunosuppressants. A recent study showed that about 7% of such patients are not protected against measles according to the lack of documentation in the vaccination card or the absence of protective antibodies. The Standing Committee on Immunization (STIKO) recommends a first vaccination against measles as a measles-mumps-rubella combined vaccination (MMR) in children aged 11-14 months and a second vaccination at 14-23 months. For adults born after 1970, vaccination against measles is recommended if they have not yet been vaccinated against measles or have only been vaccinated once against measles or if their vaccination status is unclear. In April 2019, STIKO published instructions for vaccinations recommended for immunodeficiency. Since March 1, 2020, measles vaccination have been compulsory in Germany.
