Volunteer Blood Donors May be Eligible to Donate CCP, Saving Lives
A: The initial antibody screening test that Carter BloodCare uses is unlikely to be positive after a blood donor receives a COVID-19 vaccine.
The antibodies that are generated after a vaccine are not detected by the antibody screening test that Carter BloodCare uses for blood donations. Every test detects a certain part of the virus. Your lack of a positive antibody test result means our test doesn’t detect the response to the vaccine; but it does not reflect on the effectiveness of the vaccine.
