Funny, I swear I debunked this a day or so ago.
It is COMMON for scientists working in molecular biology to work with genetic sequences and NEVER have the original organism. I don’t need a mouse to make mouse proteins, I only need the sequence of the protein I want. For a virus, as long as researchers have a sequence, they can make any genetic material or viral protein they want. No virus needed.
Way to misrepresent the hell out of the subject.
Tell me the number of other vaccines which are based on a single protein from the microorganism being vaccinated against.
