You're right. I linked the wrong article. Sorry about that. Use this one.
Q. Is [human] fetal cell DNA contained in vaccines?
A. Because vaccine viruses go through several steps of purification
and because DNA does not withstand these processes very well,
any components of DNA that remain are highly fragmented and
minimal. When DNA from the production process has been
measured in vaccines, it was only present in picogram quantities.
A picogram is one-trillionth of a gram (0.000000000001). As such,
this small amount of fragmented material is not able to cause
damage or interact with our own DNA.
