Viruses are not alive. They are just a complex chemical substances that trick living cells to copy them. That's all.
You infect cellular cultures, or eggs with it (different viruses grow better in different mediums) and then boom you get as many viruses you want.
Yes. Then you separate viruses from medium and get industrial amouns of viruses as intermediate ingridient of vaccine. It is described in every medicine schoolbook and for each and every virus vaccine was made for, there is a peer-reviewed scientific paper describing whole process of taking a virus, preparing medium, replicating virus, separating it from medium and measuring the purity of result.
But nobody, nowere got any amount of pure, clean SARS-CoV-2 viruses. Not even a dozen of them. SARS-CoV-2 was never isolated. You can't have industrial amounts of virus if nobody nowhere get even few of them.
If you have no industrial amount of viruses you can't do the following:
You then just need to inactivate the virus particles and the vaccine is done.
Simple like that. You can't make a traditional vaccine if virus was not isolated.
