Below is a link to CDC-006-00019, Revision: 07 CDC/DDID/NCIRD/ Division of Viral Diseases Effective: 07/21/2021
On page 40 of this document you will find the following text

“Since no quantified virus isolates of the 2019-nCoV were available for CDC use at the time the test was developed and this study conducted, assays designed for detection of the 2019-nCoV RNA were tested with characterized stocks of in vitro transcribed full length RNA (N gene; GenBank accession: MN908947.2) of known titer (RNA copies/µL) spiked into a diluent consisting of a suspension of human A549 cells and viral transport medium (VTM) to mimic clinical specimen.”

My questions are as follows:
How is it that at the time of this publication (REV 7 21 July 2021 OVER 18 MONTHS INTO THIS) there were “no quantified virus isolates of the 2019-nCoV available for CDC use”?
How is it that CDC expects to develop and recommend proctoring methods of a test when said test did not have the very pathogen to test against that is the purported subject of the test?

At the risk of coming off repetitive. How the hell am I supposed to believe anything out of CDC regarding this matter when there are no quantified virus isolates of the 2019-nCoV available?

Why are there no quantified virus isolates of the 2019-nCoV available?

If there are no quantified virus isolates of the 2019-nCoV available. What the hell are we “vaccinating” against?

I would like some answers.
