Abstract
We compared the effect of intramuscular vs. inhaled 23-valent pneumococcal capsular polysaccharide vaccine (23-PPV) oil pulmonary mucosal immunoglobulin levels. Bronchoalveolar lavage (BAL) and serum were collected from 33 adults before and I month after injected (n = 16) or inhaled (it = 17) 23-PPV. Levels of pneumococcal capsule-specific IgG and IgA to types 1, 9V and 14 were measured in each sample. Injected 23-PPV produced a significant increase in types 1, 9V and 14 capsule-specific IgG and type I IgA in both serum and BAL (type I geometric mean BAL IgG 9.8 ng/ml post-vaccine vs. 5 ng/ml pre-vaccine, p = 0.01; type 9V geo mean 5.6 ng/ml vs. 2.7 ng/ml, p = 0.001; type 14 geo mean 23.6 ng/ml vs. 6.2 ng/ml, p = 0.02). Inhaled vaccine produced no response in either BAL or serum. (C) 2008 Elsevier Ltd. All rights reserved.
