Questions About the COVID-19 Vaccine

Yes. There are several vaccines being used in clinical trials and some of these vaccines may be approved for general use very soon.

Examples include Pfizer/BioNTech, Moderna, Janssen/Johnson&Johnson, AstraZeneca, Sanofi, Novavax. Donation is safe if you have been given any of these vaccines. If you are participating in a clinical trial, and the protocol asks you not to donate blood for a period of time, you should follow those instructions. 

No, our antibody test is not likely to be positive following the vaccine.

Our screening test is designed to detect a variety of antibody that forms when you have actually been ill with the coronavirus.

Frequently Asked Questions about the COVID-19 Antibody Testing 

The COVID-19 antibody test will show if your immune system has responded to the virus by producing antibodies. Most people who have antibodies will have had some symptoms of the disease, such as fever, cough, or trouble breathing, but some persons may have antibodies even though they never had symptoms. COVID-19 antibody testing will be performed in addition to the standard infectious disease testing all blood donations received. 

Gulf Coast Regional Blood Center is using the Roche Diagnostics Elecsys Anti-SARS-CoV-2 Test and the Ortho VITROS Immunodiagnostic Products Anti-SARS-CoV-2 IgG. These tests are authorized by the FDA under an Emergency Use Authorization, which means it can be used only during the time of the Coronavirus pandemic crisis. This test is authorized by the FDA only for detecting the presence of antibodies against SARS-CoV-2 and is not intended for diagnosis of COVID-19. 

No. The COVID-19 antibody test does not test for the presence of the virus that causes COVID-19. The antibody test looks to see if the blood contains antibodies to the virus. The test does not check for the presence of an active COVID-19 infection.

The treatment is known as COVID-19 convalescent plasma.
