The use of fetal tissue in vaccine development is the practice of researching, developing, and producing vaccines through growing viruses in cultured (laboratory-grown) cells that were originally derived from human fetal tissue.[1] Since the cell strains in use originate from abortions,[2] there has been opposition to the practice and the resulting vaccines on religious and moral grounds.[1][3][4]
The vaccines do not contain any of the original fetal tissue or cells or cells derived from fetal materials.[5] Although the vaccine materials are purified from cell debris, traces of human DNA fragments remain.[6][7][8] The cell lines continue to replicate on their own and no further sources of fetal cells are needed.[5]
The Catholic Church has encouraged its members to use alternative vaccines, produced without human cell lines, if possible. However, the Vatican has clarified that "all vaccinations recognized as clinically safe and effective can be used in good conscience, with the certain knowledge that the use of such vaccines does not constitute formal cooperation with the abortion".[9]
