Context: On 25 November 2018, Regalado posted on MIT Technology Review website that He Jiankui was making CRIPSR babies. As it was publicised, He was prompted to announce his experiment and posted the news of the birth of twins, nicknamed Lulu and Nana, on YouTube in five videos the same day. He formally presented the experiment at the Second International Summit on Human Genome Editing organized at the University of Hong Kong on 28 November 2018. He explained that the experiment was to make the babies resistant to HIV infection as they were (as embryos) obtained from an HIV-positive father. He specifically used a mutant gene named CCR5-Δ32 that is known to confer innate resistance to HIV. The twins were born in secrecy in October 2018, and a third baby (revealed in 2022 as Amy) was then almost born, as He reported.
