The results showed that, 2 weeks after the primary vaccination (day 14), both of VLPs and inactivated H120 groups could not detected serum IgG titers, and the differences between these and PBS groups were not statistically significant (P > 0.05); but following the second immunization (day 28), the IgG titers of the VLPs and inactivated H120 groups increased (Fig. 6 ) and were significantly higher (P < 0.01) than the PBS group. The results showed that VLPs and inactivated H120 groups had statistically significantly higher neutralizing antibody titers (P < 0.01) than the PBS group (Fig. 7) . Virus like particles (VLPs) and inactivated H120 groups had significantly higher neutralizing antibody titers (P < 0.01) than the PBS group.	./cache/cord-262940-eyejnexx.txt	./txt/cord-262940-eyejnexx.txt
