I received the first shot around late March and my second shot late April. I felt the most side effects after my first shot. I had a severe headache and stomach aches. It made me want to sleep all throughout the next day. Additionally, my shoulder hurt when I would move it, not even in the exact area that the needle went through. It made my entire arm sore when I lifted it. This went on for about a week until I recovered. I did not receive as harsh symptoms for my second shot.
