The flu vaccine given to children during allergy seasons and before the winter season contains a small amount of pig gelatin, which is why many Muslims refuse to give it to their children. As for me, I give the vaccine to my daughter because she suffers from chest allergies that trouble her a lot, and her health improves when she receives the vaccine. My friend wants to give the vaccine to her daughter due to the spread of the coronavirus, but she is hesitant. What do you advise her?
