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.
First of all it was only 1 of the 4 that has aborted fetal cells and at the time they said that the ingredients were listed on the CDC and yes they included aborted fetal cells.
