establish provisions related to the disclosure of COVID-19 and mRNA vaccination status and blood donations.

HB 1171 requires blood donation centers in South Dakota to ask donors if they've received a COVID-19 or mRNA vaccination and to label blood bags if they have. It prohibits disclosing the donor's personal information on the label. Patients needing non-emergency blood transfusions can request blood from donors with or without these vaccinations, and healthcare providers must provide that blood if available. The law directly affects blood donors, donation centers, and patients receiving transfusions, creating new disclosure and request mechanisms while banning discrimination based on vaccination status.
