COVID-19 testing has spawned a veritable cottage industry, with medically minded entrepreneurs stepping up to meet increased demand — often charging top dollar to expedite PCR test results.

The CDC's emergency use authorization for its PCR test will be withdrawn in January because the demand for diagnostic tests has been met.

The PCR test currently used to test for COVID-19 was, indeed, created for that use. It's not a vaccine in disguise.
