Recommendations for specialists for diagnosis and therapy
plus patient information sheets

It is generally recommended that all persons aged ≥ 18 years should have basic immunity against Severe Acute Respiratory Syndrome Coronavirus Type 2 (SARSCoV-2). Basic immunity is achieved through at least 3 SARS-CoV-2 antigen contacts due to vaccination or infection. At least 2 of the 3 antigen contacts should have been vaccinated. There are specific recommendations for people with underlying conditions that are associated with an increased risk of severe COVID-19. These underlying diseases also include diseases of the central nervous system such as multiple sclerosis (MS).
Persons aged 6 months or older with an underlying disease with an increased risk of severe COVID-19 should receive further booster vaccinations in the future – usually at least 12 months after the last known antigen contact caused by vaccination or infection. If the last known antigen contact was at least 12 months ago, the booster vaccination should preferably be administered in the fall.
