הנדסת תינוקות – הכשלון והשבר

לפני למעלה משנה דיווחו העיתונים בארץ ובעולם^[2,1] שהֵה ג'יאן-קווֵי (He Jiankui), מדען סיני מהעיר שן-ז'ן שבסין הודיע שהצליח לשנות (לשכתב) את הגנום בביציות אנושיות מופרות. המדען השתיל את העוברים ברחם אמם ונולדו תאומות הנקראות לולו וננה. העילה המוצהרת לשינוי הגנטי שעברו הייתה ליצור אצל התינוקות חיסון מולד נגד איידס^[3] מאחר שאביהן של התאומות הוא נשא איידס.

הדיווחים בתקשורת הגיעו לאחר שהֵה סיפר על הניסוי הנועז שלו בכנס הבין-לאומי השני לעריכה גנטית שהתקיים בהונג קונג בנובמבר 2018. המדען הצהיר בהתלהבות שעשה פריצת דרך מדעית העשויה להוביל למיגור מגפת האיידס בעולם. עם זאת, אף מגזין מדעי לא הסכים לפרסם את המאמר המדעי של המדען. הוא נדחה על ידי עורכי העיתונים המדעיים החשובים כמו Nature והעיתון של החברה האמריקנית הרפואית The Journal of the American Medical Association.
