Besides dosing factors, epidemiological factors (such as number of competing strains and bacterial excretion) influenced resistance development and need to be considered further in relation to optimal treatment strategies.

Here we describe a new LAV candidate with unique cross-protective abilities: BA71ΔCD2. Thus, inoculation of BA71ΔCD2 protected pigs not only against the experimental challenge with BA71, the virulent parental strain, but also against heterologous viruses, including Georgia 2007/1, the genotype II strain of ASFV currently circulating in East Europe.
