Hospital staff must swear off Tylenol, Tums to get religious vaccine exemption

8. Your point is well taken. I had questions about the same issue until I ran across this piece

which points out how many medications have been retested since they were first introduced. The following was written by a Catholic priest opining on the hypocrisy of objecting to vaccines that had only been tested, not manufactured, using fetal cell lines. He prepared his thoughts with the help of Dr. Lisa Gilbert, MD.

Dr. Gilbert also shared some info on why HEK-293 testing is so ubiquitous.

This is often used in basic research, which helps to establish how diseases cause bad effects at the cellular level, such as on the cell receptors, ion channels or protein expression and folding. This knowledge allows researchers to look for or even create new medications to counteract these specific diseases more precisely, by targeting the cause and effects of diseases at the cellular and molecular level. More directly, HEK is used to test various medications and evaluate see their effects on the cells in-vitro.

This allows safety and efficacy testing to be done in the lab before medications are given to patients in clinical trials. Or HEK call lines may be used to study old medications that are already available and FDA approved. There may be new applications for these medications; knowledge of how these medications work at the cellular level will help in targeting diseases better. These medications may also have side effects or cause interactions on cells when combined with other medications. Studying this in the lab allows for side effects to be understood and mitigated. New medications in the same class can be developed that are safer or more effective. But all of these research possibilities require living cell lines and one of the most common ones chosen for such research is HEK.

Apparently, older medications are being retested in the lab all the time, either to improve them, or to develop replacements that are just as/more effective with fewer side effects. Hope this helps.
