I had a friend, that on her wedding day her husband to be came down with Bell's Palsy. The whole left side of his face was frozen and his left eye drooped down. It looked like he had a stroke. He could hardly talk and it was frightening to see that happen a young, 24 year old guy. Thankfully he recovered within a few days, but there is no way I am taking that vaccine if that may be one of the side effects.
