Donated blood-mRNA disclosure.

HB 152 requires blood donors in Wyoming to disclose if they've received a COVID-19 or mRNA vaccine. Blood from vaccinated donors must be clearly labeled on packaging and related paperwork. Patients receiving blood transfusions (in non-emergency situations) can request blood from unvaccinated donors if available at their facility. The bill defines key terms like "mRNA vaccine" and directs the state health department to create implementing rules. It does not change blood safety standards but adds disclosure and labeling requirements for donor vaccination status.
