No announcement of a genetically engineered human baby or credible plan for one will occur in 2017.

This is judged on the outcome, not on the 90% figure. TRUE if no public announcement was made between 1 Jan and 31 Dec 2017 of (a) a genetically engineered human baby (an engineered embryo carried to birth or to an ongoing pregnancy) or (b) a credible plan to produce one, meaning a named researcher, clinic or institution publicly stating a concrete intention to implant gene-edited embryos to establish a pregnancy. Laboratory editing of embryos that were never meant for implantation (for example research on non-viable or discarded embryos) does not count as a baby or as a plan. MOSTLY TRUE if the only candidate in 2017 is a borderline case: a vague or speculative statement of intent with no named team, method or timeline. MOSTLY FALSE if a statement of intent was made in 2017 that some credible observers treated as a real plan but most did not. FALSE if, during 2017, such a baby or a concrete, credible plan to implant gene-edited embryos was publicly announced. Announcements made after 31 Dec 2017 do not count either way.

Set before the research began.

   “Mitalipov and colleagues explicitly conducted the experiments to improve the safety and efficiency of gene editing for eventual clinical trials, which would involve implanting edited embryos into women’s uteruses to establish pregnancy.”

   ““This paper is not announcing the dawn of the designer baby era,” says R. Alta Charo, a lawyer and bioethicist at the University of Wisconsin Law School in Madison.”

   “The researchers had no intention of implanting the altered embryos in a uterus.”

   “But not soon, and probably not in the United States. Federal law prohibits regulators from even considering a request to launch a clinical trial in which embryos would be genetically altered and implanted in a uterus.”

The only 2017 candidate in the evidence is the Mitalipov embryo-editing study. It was done to improve safety for "eventual clinical trials" involving implantation (E1), but the researchers had no intention of implanting these embryos (E3). Observers said it did not announce designer babies (E2) and that implantation would come "not soon" because US federal law blocks such trials (E4). That makes it at most a vague, borderline statement of intent with no timeline. The evidence does not include a comprehensive review of the whole of 2017.
