Nemo,
I just lost a post - probably because ALL of those freakin asterisks you added to the title.
Look. The coronavirus causing covid-19 - also known
as the wuhan-flu has been isolated and its genome mapped. By many different folks.
Try following and reading the two links.

SARS-CoV-2 (COVID-19) Genome
Complete genome of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) isolate Wuhan-Hu-1, also known as COVID-19.

Two genome sequences of coronavirus (COVID-19) show possible internal transmission
(from deep in this article)
Different genomes
The team has found that the genome sequence of the coronavirus sampled from the first confirmed case in Brazil is different from the one acquired from the second confirmed case in the country. Further, the two complete genome sequences were different from the patients in China.
The scientific discovery has been added to an international database where about 22 countries have sequenced the virus genomes,

Given the state of the art in DNA analysis I'd be shocked if they had not isolated and mapped the genome of the wuhan flu.
But, given the different mutations already discovered . . . I have doubts as to the efficiency of the existing vaccines.
