Figure 1From: Duration of protective immunity and antibody responses in cattle immunised against alcelaphine herpesvirus-1-induced malignant catarrhal feverELISA analysis of virus-specific antibody responses in vaccinated animals from groups 2–4 prior to challenge. Average virus-specific antibody titres in plasma (filled squares, solid line) and in nasal secretions (open squares, broken line) were plotted for all unchallenged animals available at each time point. Error bars correspond to the standard error of the means.Back to article page
