To come back to your question, a person who is a Strep carrier but does not develop symptoms (called a healthy carrier) is not necessarily 100% protected against infection, but the chances of getting Strep throat could be somewhat reduced. This person will not be treated with antibiotics anyway, as this could well eliminate the Streptococcus that was not causing the problem, as well as many other "good" bacteria and thus increase the chances of developing the infection later.
