a
Data are expressed as means ± SD. Values are CD45+ CD3+ CD8+ CD4− events as a percentage of CD45+ CD3+ events. NV, nonvaccinated; V, vaccinated.
b
Model included diet, day, and interaction: model P value (day P value). All diet and interaction P values > 0.05.
c
Model included diet, vaccination, and interaction: model P value (vaccination P value). All diet, vaccination, and interaction P values > 0.05.
