HIA serum titers and percent virus neutralization in DRAGA mice sublethally (LD₅₀)-infected with A/H3N2 Hong Kong or A/H3N2 Victoria virions. (as per Figure 10).

HK-infected mice #	dpi	M1	M2	M3	M4	M5	F1	F2	F3			Humans era
HIA titers		1:40	1:40	1:40	1:100*	1:100*	1:20	1:20	1:40			1:320**
Percent of virus neutralization		40	40	40	100	100	20	20	40
Victoria-infected mice #	32	M1	M2	M3	M4	M5	F1	F2	F3	F4	F5
HIA titers		1:20	1:20	1:20	1:20	1:80	1:20	1:40	1:40	1:40	1:120*	1:560**

M1-M5 male mice and F1-F3 female mice infected with Hong Kong virus and assessed at 32 dpi; M1-M5 male mice and F1-F5 female mice infected with Victoria virus and assessed at 32 dpi. * Highest HIA titer to the virus. Percent viral neutralization among individual mice was calculated based on the highest HIA titer in each group. ** HIA titers of a vaccinated individual with 2014 AFLUVIA vaccine and assessed in 2015.
