A new video overview of the COVID-19 vaccine label for AtraZeneca’s vaccine reveals that it’s made with MRC-5, a strain of aborted human fetal tissue.

The video was originally posted to Instagram. It walks the viewer through a closer look at the packaging labeling of the AtraZeneca COVID-19 vaccine, beginning with the ChAdOx1-S(recombinant) designation on the label. This ingredient leads the viewer down a rabbit hole of online research, eventually discovering that recombinant strains used in the vaccine are grown from the aborted fetal tissue of a 14-week-old aborted human baby.
