Pprecaution measures and Vaccination from the Perspective of Islam

According to the religion of Islam, man is obliged to take care of his health and never neglect his means of health and well-being; but to use them reasonably and correctly as much as possible. Prevention in Islam is more important than treatment and in terms of result is considered a kind of treatment. In this article, which briefly discusses the Sharia ruling on vaccination and prevention, we can generally say that in Sharia law the vaccine is permissible against any disease that is feared to be spread, and there is no difference between it and treatment. Of course, according to the nature of the materials used in vaccine ampoules and its drops, its ruling can be summarized in the following three ways.The first form is that the substances that are injected into the human body as a vaccine are permissible and Halal, in which case there is no problem in permitting it.The second case is that the substances from which the vaccine is made are Haram and harmful, however, because of mixing other materials into it and as a result of the transformation, the origin of the vaccine will be changed, and consequently, Sharia’s position will be also altered. And in some cases, on medical necessities, its use is unrestricted. The third case is that the materials used to make the vaccine are Haram and impure, and its probability of Harm is greater than its benefit, and doctors are skeptical about its usefulness and harmfulness, in which case it is clear that it is not impermissible to believe in its usefulness and to be sure of its sanctity.
