We speculate that the overall course of anti-SP IgA (with no further decline despite IgG declining, Figure 1c ) as well as the sex specific differences with an early, pronounced peak in men and a subpopulation of men with significantly higher IgA titers than the remainder (figure 2c) may be the result of an ongoing infection, which needs further attention and clarification (previous work has shown that IgA has a protective role against influenza A 9 ).	cache/cord-280544-1rhu478r.txt	txt/cord-280544-1rhu478r.txt
