Finland has expanded its national vaccination programme to provide free varicella (chickenpox) vaccines to adults aged 20 to 50 who lack prior immunity. The initiative follows guidelines from the Finnish Institute for Health and Welfare (THL) and targets the estimated 1–3% of the adult population that has never been infected or vaccinated.

The program prioritizes specific groups, including healthcare workers, individuals planning pregnancy, and those beginning immunosuppressive treatments. Implementation is being managed by regional wellbeing services, such as those in South Savonia, Satakunta, and North Savo. Residents can access the vaccine through primary healthcare centers, digital services, or phone consultations, utilizing the Varivax vaccine via a standard two-dose schedule.
