Vaccination is split into a two-phase system. The first phase is split into two parts with the first part for the elderly, medical staff, and people working in social services. The second part of the first phase, from March until the end of June, saw people with chronic illnesses and elderly people register first for the vaccine, and younger people added as more vaccine is available. Priority vaccination of teachers and of some people with chronic diseases has already ended. The second phase started on June 1, 2021, and is categorized as “voluntary and general vaccination of citizens," and anyone with public health insurance, from one of the seven public insurers (see above), aged 16 and over, can be vaccinated. The vaccination age was later lowered to 12.
