Hyperbolic falsehoods? Prove me wrong.
“Made from humanized mice installed with dead baby body parts. No thanks.”
This sounds like the BS scare story that the kooks were pushing about the HEK-293 cell line that was used for testing Covid vaccines. It’s an immortal cell line that originated from an embryo kidney cell in the 1970s and it’s been used for testing drugs ever since. The kooks love to claim that it’s in the drugs themselves when it never has been, it’s a test bed for drugs.
“Humanized mice” is probably supposed to be “humanized antibody” since tocilizumab is a “humanized antihuman IL-6 receptor antibody”. There’s also monoclonals known as “chimeric antibodies” that have an animal origin but tocilizumab isn’t one of those.
Humanized mice do exist but like the immortal embryo cell line they are for testing.
