Pneumococcal Conjugate Vaccine With Pneumococcal Polysaccharide Vaccine and Tetanus/Diphtheria Vaccine
Pneumococcal Conjugate Vaccine (Prevnar; Wyeth) With Pneumococcal Polysaccharide Vaccine (23-valent) and Tetanus/Diphtheria Vaccine
Study Overview

Conditions
Detailed Description
The only vaccine licensed in the United States for protecting adults against pneumococcal disease (PPV23) protects against invasive disease in observational studies but has generally been poorly effective against pneumonia or all-cause mortality in randomized clinical trials. Another vaccine containing seven polysaccharide antigens conjugated to diphtheria toxoid (PCV7) is licensed for children and under investigation in adults.
In this pilot study, we are comparing the safety and immunogenicity of three immunization schedules in adults:
- Td vaccine, 2-week interval, PCV7, 4-month interval, PPV23
- PCV7, 4-month interval, PPV23
- PPV23
We aim to:
- compare the safety profiles of pneumococcal vaccines given on each of the three schedules
- compare serotype-specific ELISA antibody response to pneumococcal antigens given on each of the three schedules
- compare functional serotype-specific antibody responses to pneumococcal antigens given on each of the three schedules
- study the influence of diphtheria antibody levels at the time of pneumococcal conjugate vaccine administration on the magnitude of the immune response to pneumococcal antigens
