MYTH: The Oxford vaccine contains parts of aborted foetus
FACT: A Facebook user falsely claimed that the vaccine uses MRC-5 cell lines which were “originally developed from research deriving lung tissue of a 14-week-old aborted Caucasian male foetus”.
AstraZeneca has confirmed its vaccine was not developed using MRC-5 cell lines but does use a different cell strain taken from a female foetus aborted in the 1970s.
The cells are used to propagate the virus for the vaccine but these cells do not make it into the final jab.
MRC-5 cells are also not the same cells from an aborted foetus. They are cell lines that have been grown in a laboratory from a primary cell culture originally taken from a foetus.
