A new blood test that measures a specific immune response could show how much protection a person has against COVID.
That’s according to a new study that also reveals the test shows immunity to the virus no matter if it’s a natural response or from a vaccine. Next up are clinical trials so they can get approval for use by the FDA and the European Medicines Agency.
Each test would only need a small amount of blood and would cost about $50. Research is continuing.
