Now normally any COVID vaccine or any experience I have had with them doing it with me or watching them doing for my family, they turn straight into the side of the arm you know the side of the arm that comes down below the shoulder you know what I am saying okay, and they come just straight in. This one yesterday, she went towards back of the arm and she did it at an angle. "Consumer was informed about the role of Pfizer Drug Safety and Pfizer Medical Information Department for the concern.
