No, the vaccine will not cause a positive COVID-19 PCR or antigen laboratory test result. This is because the tests check for active disease and not whether an individual is immune or not. However, because the COVID-19 vaccine prompts an immune response, it may be possible to test positive in an antibody (serology) test that measures COVID-19 immunity. [7]
