Table 2.

Neutralization antibody titer in murine sera.

Vaccine	Dose (PFU)	Route^a	IC₅₀	IC₉₀
MVTT_ZCI	10⁶	i.m.	2^3.8	2^2.3
	10⁴	i.m.	<2	<2
	10⁶	i.n.	2^4.8	2¹
	10⁴	i.n.	<2	<2

VTT^b	10⁶	i.m.	2^6.1	2^2.7
	10⁴	i.m.	2^4.5	2^1.8

i.m., intramuscular inoculation; i.n., intranasal inoculation.

Since VTT kills mice via i.n., the i.n. Nab titer was not determined in this group. Neutralization antibody titer was calculated by determining the highest serum dilution (1:2 serial dilution) to achieve 50% or 90% viral inhibition.
