Exposure to Streptococcus pyogenes (Strep A) that causes mild or no symptoms can trigger the body’s immune response and naturally build protection, potentially solving a nearly 100-year-old mystery of immunity.
New Griffith University research, with the help of clinical scientists from the Murdoch Children’s Research Institute (MCRI), investigated how immunity developed over time as infection rates declined with age, suggesting progressive immune protection. The paper “Subclinical exposure to Streptococcus pyogenes drives the development of long-lived homologous immunity” has been published in Nature Communications.
Strep A is a common bacterium that can cause painful tonsillitis and impetigo in young children and teenagers...
