Can a person build up an immunity to strep throat?

Yes, it is possible for a person to build up an immunity to strep throat over time. When the body is exposed to a harmful agent like the bacteria that causes strep throat, its immune system mounts an immune response to fight off the invaders. As a result, the organism may develop memory cells capable of quickly detecting and neutralizing the strep throat-causing bacteria if exposed to it again in the future.

This acquired immunity helps the individual become resistant to subsequent strep throat infections. However, it's important to note that immunity is not always absolute, and certain strains of the streptococcus bacteria or changes in a person's overall immunity might mean there is still a risk of developing strep throat in the future
