  1. aGroup mean antibody responses are given as log transformed antibody units. Values ≥ 1476 were considered positive. Student t-test was developed to different groups.
  2. bp < 0.05 and cp < 0.001 compared with < 20 in group 1.
  3. dp < 0.05 compared with < 25 in group 2.
  4. P< 0.05 was considered significant. SE standard error.
