Immune Response to Pneumococcal Polysaccharide Vaccine (23-valent) Predicts Asthma Status and Outcomes in Late Adolescents With Asthma
- Conditions
- Asthma
- Interventions
- Biological: Pneumonococcal Polysaccharide Vaccine 23-valent (PPSV-23)
- Registration Number
- NCT02719379
- Lead Sponsor
- Rohit Divekar
- Brief Summary
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.

- Arm && Interventions
Group Intervention Description Asthmatics Pneumonococcal Polysaccharide Vaccine 23-valent (PPSV-23) 19-20 year old asthmatics who agree to participate in study will have serum collected for analysis. PPSV23 vaccine \[Pneumonococcal Polysaccharide Vaccine 23-valent (PPSV-23)\] will be offered per the ACIP/CDC guidelines. Those who agree to receive the vaccine will have a second draw for serum 4-6 weeks post vaccination for immunization response. They will also be follow up after 1 year to assess for asthma control and outcomes. This arm will additionally allow for comparison of asthma outcomes and vaccine response Non-asthmatics Pneumonococcal Polysaccharide Vaccine 23-valent (PPSV-23) 19-20 year old non-asthmatic smokers who agree to participate in study will have serum collected for analysis. PPSV23 vaccine \[Pneumonococcal Polysaccharide Vaccine 23-valent (PPSV-23)\] will be offered per the ACIP/CDC guidelines. Those who agree to receive the vaccine will have a second draw for serum 4-6 weeks post vaccination for immunization response. This arm will allow for comparison of vaccine response between asthmatics and non-asthmatics (smokers) Asthmatics - Serum Stored Pneumonococcal Polysaccharide Vaccine 23-valent (PPSV-23) Once the accrual for the experimental arm is met, 19-20 year old asthmatics who wish to participate in study will have serum collected for analysis. PPSV23 vaccine \[Pneumonococcal Polysaccharide Vaccine 23-valent (PPSV-23)\] will be offered per the ACIP/CDC guidelines. This arm will allow for study of baseline vaccine titers to pneumococcus in asthmatics at same time increase the vaccine uptake in the community.
- Primary Outcome Measures
Name Time Method Change in asthma Control Status approximately 1 year Change in asthma control status will be assessed at end of 1 year follow up. Included would be Asthma Control Test (ACT) Score
- Secondary Outcome Measures
Name Time Method Comparison of PPSV23 vaccine serotype specific antibody response between asthmatic and non-asthmatic smokers Vaccine response will be measured at 4 to 6 weeks after administration of vaccine Vaccine response in form of serotype titers to pneumococcal antigens will be measured 4-6 weeks after vaccination and post vaccine titers will be compared with pre-vaccine titers between asthmatics and non-asthmatics (smokers)
