Neutralization of FMDV O1Campos by sera from vaccinated animals.

<p>(A) % of virus neutralized by serum from cattle immunized with B₂T, B₄T or a single dose of conventional vaccine, at 38 and 44dpv (upon 2 and 3 doses of peptide, respectively). A 1/8 serum dilution was incubated with different doses of FMDV O1 Campos, and the infective virus recovered was determined by a TCID50 assay. Titers are expressed as the % of the initial virus neutralized upon incubation. Significant differences from dose are indicate as ***(p<0.001).
