NOTE: We have researched the pre-clinical development and testing of mrna-1010 and found, not surprisingly, that the Moderna mRNA flu shot was developed and tested with the use of aborted fetal cell lines. Specifically, mrna-1010 used HEK-293FT cells, a variation of HEK-293, to test antigen expression in a manner similar to how the COVID-19 vaccines were tested. The information on the development and pre-clinical testing is found in this paper, published in December of 2021 on the National Institute of Health website.
The ethical fault is clear. This drug would not exist but for its reliance on aborted fetal cell lines to test and validate the mechanism of action. A person of faith is called upon to avoid this influenza shot, instead choosing one of over a dozen currently approved flu shots that are not ethically compromised.
