All control mice were dead by day 7 of infection, by which time all three surviving vaccinated groups showed a further increase over background in levels of IFNγ (3000–6800-fold), TNFα (55–105-fold), IL-1α (65–72-fold), IL-1β (10–14-fold), IL-3 (4–9-fold), IL-6 (1200–1900-fold), KC (91–156-fold), MCP-1 (71–296-fold), RANTES (20-fold), and GM-CSF (9–23-fold). This evidence concerns the gene IL6 and infection.
