Ok, that's normal in animal testing, Commander.
"Histopathological examination was performed on liver sections (fixed with 10% PBS-buffered formalin, embedded in wax, and stained with hematoxylin and eosin) from ferrets sacrificed between 27 and 29 days postchallenge."
Actually, the only human Phase I/II/III trials by FDA standards:
mRNA research is at least 10 years old (older if you include trials) and was directed initially as cancer-killing vehicles to utilize the immune system to attack cancer cells, which has been vastly hit-or-miss to date; however, at least that timeline has produced a pool of patients who have not produced a statistically-signifiant, unwanted 'expression' of adverse genetic fallout from mRNA treatment.
10 years is young in testing, no doubt, and of course this was an enhanced, "Operation Warp Speed" timeline to utilize this 'still-young' delivery package for a resilient, Chinese-engineered-to-cause-a-global-pandemic SARS virus.
