rganized in collaboration with Weill Cornell Medicine-Qatar and the World Innovative Summit for Health (WISH), this edition of the Summer School focused on some of the ethical questions raised by vaccination, namely the administration of a vaccine to help one’s immune system develop protection from serious infections like smallpox, polio, measles, and most recently COVID-19. The religio-ethical discourse in the Islamic tradition explored topics like the possible tension between vaccination and trust in God and His predestination or the religiously controversial character of some ingredients of the vaccine, such as the cell lines derived from (aborted) human fetal tissues or the materials which are considered “impure” from a religious perspective, like the porcine tissues or porcine gelatin.
