Figure 7From: Evaluation of immunogenicity and cross-reactive responses of vaccines prepared from two chimeric serotype O foot-and-mouth disease viruses in pigs and cattleSerological cross-reactive responses against heterologous FMDVs. A two-dimensional (2D) virus neutralization test was performed using sera from six cows vaccinated with the rHN, rHN/NXVP1 or rHN/TURVP1 vaccine at 28 dpv. The dotted line indicates the cut-off value of 0.3. Three experiments were performed independently, and the mean r1 values were obtained from three replicates of six animals. Error bars indicate SDs from the mean.Back to article page
