In a vaccine is a weakened cell of the virus it is protecting. We inject that weak cell into our bodies. Because it is a weak cell, it can't harm us. The good cells in our bodies destroy this bad cell and remember it as a bad cell. When the real virus gets in, the good cells instantly destroys it because it had past information of this bad cell. I have no idea why all this bad stuff is in vaccines, but that dosn't mean you shouldn't vaccinate. I suggest going to a top-rated doctor to vaccinate. They know what there doing.
