They(Johnson & Johnson and Oxford) don't contain fetal stem cells in the doses themselves,..

That's not true.

When it comes to the COVID-19 vaccines, at least five candidates undergoing clinical trials use fetal-derived cell lines: from China's CanSino Biologics, the University of Oxford partnered with AstraZeneca, Janssen (a subsidiary of Johnson & Johnson), the University of Pittsburgh and California-based ImmunityBio.

Fact check: COVID-19 vaccine 'morally acceptable,' Vatican says, but some claims missing context

You're misunderstanding the word "use". They mean "use" in the context of the research and development of the vaccine; NOT the production. It even tells you how fetal stem cells were used right in your own article:

"The University of Pittsburgh uses the HEK-293 cell line to construct the SARS-CoV-2 spike protein to stimulate an immune response once injected."

And later:

"use aborted fetal cells during research and development"

No vaccine doses ever contain fetal stem cells. There would be no purpose to that.
