Tetanus and diphtheria toxoids adsorbed(MassBiologics)

This is a double-blind randomized controlled trial to test whether the group B meningitis vaccine 4 component Neisseria meningitidis serogroup B vaccine (BEXSEROTM) (4C-MenB), trade name Bexsero™), currently approved for use by the United States Food and Drug Administration (FDA) and recommended by the Centers for Disease Control and Prevention (CDC) for protection from Neisseria meningitidis infections, also protects from Neisseria gonorrhoeae infection using controlled human experimental infection to test protection. The information the investigator learn by doing this study may also help to develop a vaccine that protects individuals from having gonorrhea infection.
The study population will consist of male participants > 18 and < 36 years old, living in central North Carolina, in general good health without a history of 4C-MenB vaccination. Approximately 120-140 participants will be enrolled.
Participants will receive 2 doses of vaccine (2 doses of 4C-MenB or 2 comparator vaccines- seasonal influenza and tetanus/diptheria booster) as intramuscular injections, and then one intraurethral challenge with Neisseria gonorrhoeae. Following the challenge, participants will cross-over and receive two doses of vaccines not received prior to challenge (2 doses of 4CMenB or the 2 comparator vaccines- seasonal influenza and tetanus/diptheria booster) All participants receive all vaccinations by the end of the study and all vaccines used in this study are licensed and FDA-approved.
