    African swine fever: one hundred years later by V. V. Makarov

    Published 2022-06-01
    “…In addition to the gaps mentioned in these conclusions and recommendations there are serious gaps in African swine fever immunology, namely in protective immunity mechanisms, virus-macrophage interaction, in vitro virus phenotypic  signs correlating with its virulence, etc. Evidently, it is hardly possible to expect development of anti-ASF vaccines and particularly the vaccines capable of preventing and effectively protecting against ASF epizooty according to the general understanding without addressing these issues.…”
