Table 1. Forty volunteers were enrolled into the immunization groups (20 group CA and 20 group CAT).
16 in each group remained through CHMI. Infectivity controls (12) were enrolled later, in time for CHMI on week 28.
| Immunized Group CA n = 20 | Immunized Group CAT n = 20 | Infectivity Controls n = 12 | |
|---|---|---|---|
| Male | 11 (55%) | 14 (70%) | 8 (66.7%) |
| Female | 9 (45%) | 6 (30%) | 4 (33.3%) |
| Mean Age ± standard deviation | 33.1 ± 9.50 | 27.0 ± 6.47 | 26.0 ± 3.95 |
| White or Caucasian | 9 (45%) | 12 (60%) | 8 (66.7%) |
| Black or African American | 6 (30%) | 5 (25%) | 2 (16.7%) |
| Asian | 3 (15%) | 0 | 1 (8.3%) |
| Native Hawaiian or Other Pacific Islander | 1 (5%) | 0 | 0 |
| American Indian or Alaska Native | 0 | 0 | 1 (8.3%) |
| Unknown/Other | 1 (5%) | 3 (15%) | 0 |
There were no significant differences between groups, except the mean age of the CA group was significantly (ANOVA followed by Tukey testing) higher than the infectivity controls.
