Pneumococcal Vaccines in Patients With Asthma

Clinical Trial ID: NCT03260790


Investigators are assessing if patients with asthma respond better to the Pneumovax vaccine if they are given Prevnar initially.

Patients will be randomized into either PCV13 and PPSV23 (Experimental) or PPSV23 alone (Active comparator). At the Week 0 time point, the patients will receive either PCV13 (Experimental) or PPSV23 (Active comparator) and undergo a blood draw of 5ml for assessment of pre-vacation serotype titers. The Active Comparator group will undergo a 5ml draw of blood for assessment of titers at week 8, 16, and 24 following vaccination. The Experimental group will undergo vaccination with PPSV23 at week 8 with 5 ml blood draw for pneumococcal serotype titers as well as a blood draw at week 16 and week 24.
