Protection against transplacental transmission of moderately virulent classical swine fever virus using live marker vaccine "CP7_E2alf".

Classical swine fever (CSF) remains as one of the most important infectious diseases of swine. While prophylactic vaccination is usually prohibited in free countries with industrialized pig production, emergency vaccination is still foreseen. In this context, marker vaccines are preferred as they can reduce the impact on trade.

Deletion at the 5'-end of Estonian ASFV strains associated with an attenuated phenotype.

African swine fever (ASF) was introduced into the Eastern European Union in 2014 and led to considerable mortality among wild boar. In contrast, unexpected high antibody prevalence was reported in hunted wild boar in north-eastern Estonia. One of the causative virus strains was recently characterized.

Kinetics of maternally derived antibodies upon intramuscular vaccination against classical swine fever with Suvaxyn CSF Marker (CP7_E2alf).

Classical swine fever (CSF) remains one of the most important viral diseases that impact on sustainable pig production world wide. To control the disease in either endemic situations or in case of large, high-impact contingencies, safe and highly efficacious live attenuated vaccines exist since decades. However, until recently, the available live vaccines did not allow a serological marker concept that would be important to circumvent long-term trade restrictions.
