Cattle Response

• Vaccination Protocol: Thirty-two cattle of 6–7 months of age were housed separately in six groups of five (vaccinated animals) and one group of two (un-vaccinated controls) within the isolation units at the Institute for Animal Health, Pirbright. The six groups of vaccinates were immunised as follows: Group 1 with 2 mg PLG-pcDNA3.1/P12A3C3D + 0.4 mg pcDNA3.1/bGM-CSF (DNA + PLG + GMCSF), Group 2 with 2 mg PLG-pcDNA3.1/P12A3C3D + 0.4 mg pcDNA3.1/bGM-CSF + electroporation (DNA + PLG + GMCSF + elec), Group 3 with 2 mg pcDNA3.1/P12A3C3D + 0.4 mg pcDNA3.1/bGM-CSF (DNA + GMCSF), Group 4 with 2 mg pcDNA3.1/P12A3C3D + 0.4 mg pcDNA3.1/bGM-CSF + electroporation (DNA + GMCSF + elec), Group 5 with 2 mg pcDNA3.1/P12A3C3D + electroporation (DNA + elec), and Group 6 with conventional vaccine (Fowler et al., 2012).
• Vaccine Immune Response Type: VO_0003057
• Immune Response: All DNA vaccinated cattle generated a detectable neutralising antibody response at 21 days post 1st vaccination (Fowler et al., 2012).
• Challenge Protocol: On day 133 post primary vaccination, four cattle in each of vaccination groups 3–6 only were randomly selected, together with two un-vaccinated controls and intradermolingually challenged in two sites with 105 TCID50, 0.1 ml per site, of cattle adapted O1 Lausanne FMDV (Fowler et al., 2012).
• Efficacy: Conventionally vaccinated cattle were fully protected from experimental challenge, as determined by absence of generalised disease (Table 2). In addition 6 of the 8 DNA vaccinated cattle in groups 4 and 5 (DNA + GMCSF + elec and DNA + elec) were fully protected despite these DNA vaccinated animals being challenged 91 days after the protein boost (Fowler et al., 2012).
