Intervention type: OTHER
Group type: EXPERIMENTAL
Intervention: VRC-GENADJ0110-AP-NV
Description: Adjuplex is an adjuvant, a sterile, pyrogen-free adjuvant solution produced by VRC Pilot Plant. Adjuplex comprises highly purified de-oiled soy lecithin and benzene-free carbomer homopolymer formulated in phosphate buffered saline at a pH of 6.5 plus or minus 0.3. Adjuplex adjuvant will be mixed with FluMos-v1 at 20% by volume in the pharmacy during product preparation for the vaccinations of Groups 5A-5B, 6A-6B, and 8A-8B.
