modification to this day, whereas there are still a number of limitations that keep the technique from being labelled as safe and efficient. During the First International Summit on Human Gene Editing in 2015 the participants agreed that a halt must be set on germline genetic alterations in clinical settings unless and until: "(1) the relevant safety and efficacy issues have been resolved, based on appropriate understanding and balancing of risks, potential benefits, and alternatives, and (2) there is broad societal consensus about the appropriateness of the proposed application". However, during the second International Summit in 2018 the topic was once again brought up by stating: "Progress over the last three years and the discussions at the current summit, however, suggest that it is time to define a rigorous, responsible translational pathway toward such trials". Inciting that the ethical and legal aspects should indeed be revisited G. Daley, representative of the summit's management and Dean of Harvard Medical School depicted Dr. He's experiment as "a wrong turn on the right path". The experiment was met with widespread criticism and was very controversial, globally as well as in China. Several bioethicists, researchers and medical professionals have released statements condemning the research, including Nobel laureate David Baltimore who deemed the work "irresponsible" and one pioneer of the CRISPR/Cas9 technology, biochemist Jennifer Doudna at University of California, Berkeley. The director of the NIH, Francis S. Collins stated that the "medical necessity for inactivation of CCR5 in these infants is utterly unconvincing" and condemned He Jiankui and his research team for 'irresponsible work'. Other scientists, including geneticist George Church of Harvard University suggested gene editing for disease resistance was "justifiable" but expressed reservations regarding the conduct of He's work. The Safe Genes program by DARPA has the goal to protect soldiers against gene editing war tactics. They receive information from ethical experts to better predict and understand future and current potential gene editing issues. The World Health Organization has launched a global registry to track research on human genome editing, after a call to halt all work on genome editing. The Chinese Academy of Medical Sciences responded to the controversy in the journal Lancet, condemning He for violating ethical guidelines documented by the government and emphasising that germline engineering should not be performed for reproductive purposes. The academy ensured they would "issue further operational, technical and ethical guidelines as soon as possible" to impose
