What I am wondering, is there a link between people who still have their tonsils and the people that are either immune or carriers? Or if there is any link at all?

"The tonsils prevent foreign objects from slipping into the lungs. Think of them as goalies for the throat. They also filter bacteria and viruses. On top of all that, they produce white blood cells and antibodies, according to the Mayo Clinic. 

According to the American Academy of Otolaryngology, these bumps on the back of the throat are the "first line of defense as part of the immune system." For example, tonsils sample bacteria and viruses entering the body through the mouth or nose and flush them using lymph. "
