-- active cancers,
-- diseases treated with permanent and relevant immunosuppression (e.g., transplants, permanent cortisone therapy, HIV),

Vaccination schedule for at-risk individuals
For optimal protection against severe disease progression and Long COVID, at-risk individuals are advised to refresh their vaccination earlier.

COVID-19 medications as an additional safety net.
COVID-19 medications do not replace vaccination. They are an additional safety net especially for people at risk. This is especially true for older people and those with pre-existing conditions. If taken in time, COVID-19 medications can prevent serious illness and thus hospitalization.
It is important that COVID-19 medications are taken as soon as possible after a positive test result. Get advice: from your doctor or at your pharmacy.

Protection of the at-risk group in the workplace
A COVID-19 risk certificate confirms a possible increased risk of severe disease progression and is issued by the:respective treating physician:in. This results in a claim for additional protective measures in the workplace, such as workplace redesign or home office. If this is not possible, a temporary leave of absence can be taken. In addition, protection against dismissal for persons with COVID-19 risk attestation has been enshrined in law for the period of the current regulation. The current rule is effective for the time being until December 31, 2022.
