It's a hell of a leap to go from gain of function research has ever happened at all to gain of function specifically on Ebola is a near-term serious risk. Is there any evidence that gain of function has ever been conducted on Ebola? I've never heard of it, and don't know where to look other than a search engine, and conducting a search there returns exactly two sources making that claim, one called "scamdemic" and one called "goldismoney." Neither seems like a particularly reputable source.
