Can any body help me for checking my paper and try to rewrite my sources and make sure that is MLA?

I already did my papers but I want someone to help me checking my papers. Also I want to mention that I have 6 and half papers, I want to reach to 7 papers. I want to make sure my sources are MLA style, and make sure to edit them. My paper is about vaccine safety and effeteness, please understand the paper before writing. However, if you have more idea you can bring it, and again please try to understand it.
