They do not contain aborted fetus cells. This is noise, and I wouldn't be surprised if it was planted by shills to discredit us.
What happens is : The pharmaceutical companies (Pfizer and Moderna in the US, AstraZeneca in UK,don't know about the others) employed cells cloned from tissue originated from freezed embryos and aborted fetuses to do the research that produced the vaccine compounds. And the vaccines are far from being the only product that employed this kind of technique in their R&D phase. This is what makes them immoral, so you can provide the conscience objection argument (doubly valid for catholics).
These are the facts, so you don't get "debooonked" by some moron who believes Snopes.
It doesn't change the fact that this is injectable poison they're trying to force upon us, and that dead babies were used to make it. It was just a rhetoric obscurity I saw fit to clarify, for the sake of spreading the truth to people. See my response to Yohan_Galt as to why
