Immune Response to Pneumococcal Polysaccharide Vaccine (23-valent) Predicts Asthma Status and Outcomes in Late Adolescents With Asthma


About this study

Advisory Committee for Immunization Practices (ACIP) from the Centers for Disease Control (CDC) recommends that children (6-18 years) and adults (≥19 years old) with chronic lung condition such as asthma or cigarette smoking be vaccinated with Pneumococcal vaccine (PPSV23). The purpose of this study is to increase awareness of vaccination to late adolescents with asthma and smokers (social aspect of study), and to recommend vaccination (which is the clinical aspect). Individuals who agree to receiving vaccine will be enrolled in research to determine whether late adolescents with and without asthma (smokers) have distinctive pneumococcal vaccine response patterns and whether such patterns are associated with subsequent variance in asthma outcomes.
