Each column shows the relative percentage of the PCV of the seven sheep within each group per study week. Black arrows highlight the 1st (week 1), 2nd (week 4) and 3r (week 7) vaccination with either vaccine. The red arrow indicates the timepoint of challenge with 5000 L3 H. contortus (week 10). Each column shows the relative percentage of the results of the PCV of the seven sheep within the group in study week 1 to study week 16. The black arrows highlight the 1st (week 1), 2nd (week 4) and 3rd (week 7) vaccination with either BVAX, GEA or NEA. The red arrows highlight week 10, when the sheep were challenged with 5000 L3 H. contortus.
