Should I get a COVID-19 screening test if I already had the COVID-19 infection within the last three months or if I am fully vaccinated?

The CDC currently recommends that those who tested positive for COVID-19 should not re-test routinely for 90 days due to persistence of positive tests despite lack of infectivity. Fully vaccinated individuals should arrange for a COVID-19 test 3-5 days after a close contact with a COVID-positive individual or if symptoms arise.
