This question has nothing to do with being for or against vaccines from a health standpoint. This is an exercise in applying Theology to modern issues. In other words its a moral question. Here it goes.... I researched ingredients to common vaccines like the Measles. An ingredient called WI-38 is an example ingredient of several found in some vaccines like measles. Its basically cells from an aborted featus' lungs from an abortion dated in 1960.. So its not a recent abortion but it was developed during the original creation of the vaccine three generations removed. In other words scientists used aborted fetus cells and currently grow those cells in a lab over the course of many years. They are reaching their maxium life in which China created WALVAX-2 in 2015 by using recently aborted fetus’. I suspect its going to replace WI-38 when its no longer viable since they have a limited lifespan. Google the names and you will find plenty of info. Is it sinful/moral to knowingly use a vaccine with WI-38 (1960 aborted fetus cells)? Is it sinful/moral to knowingly use a vaccine with WALVAX-2 (2015 aborted fetus cells)? This is not a debate over if somebody should vaccinate. Its a debate over the moral question from a theological vantage point. Through this moral question one may decide they should not vaccinate.
