This article says it is because Chinese citizens were given the SARS vaccine.
And that nCoV was a botched attempt of genetic engineering to make a weapon that affected everyone else except Han Chinese who had the SARS vaccine. Its a bit technical in parts but stick with it to the end conclusions.
Obviously they failed at that and the new engineered virus somehow escaped the bioengineering facility. And it had exactly the opposite effect.

“This article says it is because Chinese citizens were given the SARS vaccine.”
Very easy to determine if individuals were given a particular vaccine due to the antigens that would be present.
As far as I've seen, an effective SARS vaccine has not yet been developed, nor has any SARS vaccine been administered to large populations. There is a 99% chance the source you are quoting is a kook. This whole thing is serious enough without all the crazy conspiracy theories.

Is this possible?
