While the issue of aborted fetal cell line use in vaccine production is now widely discussed, there are few places that document each of these cell lines and the abortions performed to develop them from primary and official sources.
As of 16 May 2020, using mostly primary sources available on the internet, we find that at least 181 abortions have been performed to develop fetal cell lines for the manufacturing of vaccines, including the Covid-19 vaccines in development. Those cell lines are documented here.
