Dont they have yet to actually isolate a single complete sequence of any variant including the original.

Sooo how are they determining variants? how are they determining symptoms? How are they determining how contagious it is? How are they determining how deadly it is? How do they know how resistant they are to vaccines?

Just using that single argument based on their own information that they have nowhere near isolated any of these to study them it kind of makes all of these articles look like a poorly written fan fiction.
