I don't believe that's exactly correct. I could be wrong, but, my understanding is that many vaccines (many of which you are already inoculated with - MMR, Polio, etc.) were developed using cells from fetal tissue dating back to the 70's. Those cells were replicated over thousands of generations in a lab and are still being used to produce vaccines ranging from MMR (measles, mumps, rubella) to rabies, and even drugs to treat arthritis and cystic fibrosis. The vaccines themselves don't contain the actual cells - if that matters. The Covid vaccines are no different.
That's my understanding anyway. I'd bet @Ddaddy knows more since I believe he works in the Pharmaceutical industry.
