Except of course, the company states that no fetal tissues were used in the development or production of their covid monoclonal antibodies.
Since they admit to using fetal tissue in other projects and are completely open about using HEK293 for testing, why would they lie about it for this project?
Especially when they are proud of what they do and how they do it and are well aware of the public relations cost of dissembling.
Maybe they believe that testing on is less controversial than being derived from.
I don’t know. I have become a cynic about things companies say these days.
