Wyoming bill revives false claims that COVID-19 vaccines contaminate blood

A Wyoming representative introduced a bill that would require blood donors to disclose whether or not they have received any mRNA COVID-19 vaccines. A popular social media post stated this bill would allow blood donation recipients to request “non-contaminated” blood.

Risk level: Medium

Recommendation: Social media posts referencing blood that has been “contaminated” by mRNA vaccines may discourage patients from receiving blood transfusions. Talking points may emphasize that receiving a blood transfusion from a donor who has received an mRNA COVID-19 vaccine is safe and does not transfer the vaccine to the recipient.
