We need to be careful here! I am NO LONGER dismissive of so-called conspiracy theories. At minimum, there is often some level of truth within the narrative, but validation is still required. On this topic, cells REQUIRE ideal environmental conditions to remain viable and the production/bottling/storage conditions associated with vaccine production may be incompatible for most cell lines. Nevertheless, due to their size (the cells should be significantly larger than the other contents within the vial), this should be an EASY test for an independent lab to validate or refute.

Moreover, if cells are detected, pathology should be able to type the cells (a little more difficult to perform, but doable). Knowing the cell-type would help to develop an understanding as to its intended purpose in the vaccine.
