CD8A and parasitic infectious disease: These were v03, v12 and v15 from DNA/Ad (non-protected high responders); non-protected v156 from AdCA (who showed a magnitude of CD8+ T cell activities to Ap8 that was higher than protected v10 and v18); and partially-protected v194 from AdCA (who showed a focused response to Ap8 as well as a significant delay to parasitemia).
