Human saliva and newborn? Please read.

I woke up from a nap and had my own slobber on my hands. Baby was crying so I just reached for his pacifier and popped it in his mouth without thinking. Then made him a bottle with minimum hand sanitizer. I get cold sores but currently don't have one. I'm worried that it'll hurt him, can I get some reassurance :( I feel like I'm constantly paranoid something is going to happen to him.
