NCT02707692

Brief Summary

The purpose of this study is to determine the impact of Pneumococcus and Influenza vaccines on the HIV transcriptional activity in individuals who are virologically suppressed for at least 48 weeks on similar ART. The proposed study is a randomized double-blinded control trial conducted over 28 weeks. Randomized interventions will be injections of Influenza vaccine, Pneumococcal vaccine, and Placebo. Each participant will receive each injection but in a randomized order.

Outcome Measures

Primary Outcomes (1)

  • Change From Vaccination (Day 0) in Mean CD4+ T Cell-associated HIV RNA Transcription at Day 7

    CD4+ T cell-associated HIV RNA was measured before vaccination on Day 0 and again on Day 7. The Day-0 measure of CD4+ T cell-associated HIV RNA transcription was subtracted from the Day-7 measure.

    Day 0 and Day 7

Study Arms (6)

Pneumococcal, then Influenza, then Placebo vaccination

OTHER

Participants first received a 0.5 mL injection of Pneumococcal vaccine (Pneumovax-23®). After a washout period of at least 6 weeks, they then received a 0.5 mL injection of Influenza vaccine (Fluarix®, GSK). After another washout period of at least 6 weeks, the participant received a 0.5 mL injection of saline (placebo).
