Posts Misrepresent Mouse Study of Pangolin Virus

A study showed a type of lab mouse is highly susceptible to a coronavirus derived from pangolins, a scaly, cat-sized mammal. This doesn’t mean the virus is dangerous to humans. The virus is related to the one that causes COVID-19 but did not descend from it, contrary to claims that it is a “mutant COVID-19 strain.” Nor did scientists “craft” the virus.

The mRNA COVID-19 vaccines — like many other vaccines — can contain small amounts of DNA left over from the manufacturing process. There’s no evidence this residual DNA causes “turbo cancer,” or very aggressive cancer. Nor did Moderna admit that “mRNA Jabs Cause Turbo-Cancer,” contrary to an online article that misconstrues a line from a patent application.
