Summary

The purpose of this study is to evaluate the safety and immune response of a conjugated pneumococcal vaccine compared to a licensed 23-valent polysaccharide pneumococcal vaccine in elderly adults. Study participants will include 180 adults, 65 years of age or greater. Participants will be randomly assigned to 1 of 3 possible groups. Subjects will maintain a study diary to record side effects and oral temperatures for 7 days following each vaccination. Blood samples will be collected before and 1 month following each dose of vaccine or placebo. Participants will be involved in study related procedures for up to 268 days.

Conditions

  • Pneumococcal Infection

Interventions

DRUG

Placebo

Saline placebo administered in a volume of 0.5 ml intramuscularly.

BIOLOGICAL

PNU-IMUNE®23

The 23-valent pneumococcal vaccine (PS) vaccine will contain a mixture of 25 micrograms purified, pneumococcal polysaccharide of each of 23 serotypes of Streptococcus pneumoniae per 0.5 ml dose in isotonic saline and 0.01% thimerosal. The vaccine will be administered in a volume of 0.5 ml intramuscularly.

BIOLOGICAL

Nine-valent pneumococcal conjugate (PNCRM9)

Cross-reactive material 197 (CRM 197) is a product of the Corynebacterium diphtheria C7. Vaccine is prepared from pneumococcal polysaccharides of types 1, 4, 5, 9V, 14, 18C, 19F, 23F (2 mcg each) and 6B (4 mcg) covalently linked to CRM197 by reductive amination. The protein-polysaccharide combination is prepared as a lyophilized powder with aluminum phosphage which is reconsitituted before use. The vaccine will be administered in a volume of 0.5 ml intramuscularly.
