Injection During Fasting
Issue No. 1339- All sorts of injections and vaccines whether medicinal or nutrient would not invalidate fast if they are injected in muscle, as is the case with intramuscular vaccines. But intravenous injection will make the fast void whether by serum or needle. In addition, blood transfusion will invalidate fast; one should refrain from invalidators till the end of the day, and as an obligatory precaution, make up for the fast of that day as well.
