Delayed Acquisition of Rectovaginal GBS Colonization: A Hidden Benefit of GBS Conjugate Vaccines10/10/2018
Presented by Lawrence C. Paoletti, PhDEditor's Note: At 12:03 when red and blue boxes are mentioned, the correct reference is to the red and yellow boxes showing GBS types Measurable Learning Objectives: At the conclusion of this presentation, participants should be able to… 1. Relate a history of GBS conjugate vaccine development. 2. Discuss results from a clinical study to determine if an immunogenic GBS vaccine can reduce the time to first vaginal colonization by GBS.

I'll be happy to try to answer any questions on GBS vaccine development. I'm also happy to share the link (https://doi.org/10.1093/cid/ciy838) to our recently accepted paper on the SPIN trial mentioned in my presentation.

Good question. What we state in the paper is: “Non-white women and those 30 through 40 years of age had higher CPS III-specific serum antibody levels 1-month post-immunization compared to white women (log rank test, 5.97; P = 0.01) (Supplementary Figure 1) and those 18-21 years of age (log rank test; 14.48; P < 0.0001) (Supplementary Figure 2), respectively.” Since transudate serum IgG is thought to prevent colonization then, yes both age and race could impact colonization rates due to the antibody responses.
