Subject has had medical, occupational, or family problems as a result of alcohol or illicit drug use during the past 12 months.
History of a severe allergic reaction or anaphylaxis.

INCLUSION AND EXCLUSION FOR LARGE VOLUME BLOOD DRAW:

- Individuals previously enrolled in Arms A2, B2, or C2 may be asked to return to the clinic for a single additional visit. This visit would be to collect a single large volume blood sample for additional serological analysis and characterization of B cell receptor usage.

INCLUSION CRITERIA (LARGE VOLUME BLOOD DRAW):

-The following criteria must be fulfilled for a volunteer to participate in the large volume blood draw addendum:

-- Previously enrolled in 15-I-0044 in Arms A2, B2, or C2

EXCLUSION CRITERIA (LARGE VOLUME BLOOD DRAW):

- A subject will be excluded from participating in the large volume blood draw addendum if any one of the following criteria is fulfilled:

Pregnancy as determined by self report (if female).
Within the past 30 days has received a research drug or vaccine or been enrolled in another research drug or vaccine trial.
