Table 3. Antibody titer decline rates and half-life values in days with their corresponding 95% confidence intervals [95% CI].

Data are reported for each individual in the CLINICAL and SUBCLINICAL datasets as well as for the first and second phase of titer decline observed for the SUBCLINICAL animals. Rates for the CLINICAL animals are ordered from high to low with the median decline and half-life values in bold italics. The titer decline rate marked with an asterisk (*) was not significantly different from zero.
