Viral haemorrhagic disease of rabbits: vaccination and immune response.

Vaccination against and immune response to viral haemorrhagic disease of rabbits: a review of research in the People's Republic of China.

Viral haemorrhagic disease (VHD) of rabbits is an acute entity with high mortality which affects adult rabbits. Several vaccines have been developed in China and extensive use of these vaccines in the field has controlled the spread of the disease. Formalin inactivated tissue vaccine induces solid immunity on the third to fourth day post vaccination and immunity lasts for at least six months. T...

Effects of vaccination against viral haemorrhagic disease and myxomatosis on long-term mortality rates of European wild rabbits.

The effects of vaccination against myxomatosis and viral haemorrhagic disease (VHD) on long-term mortality rates in European rabbits (Oryctolagus cuniculus) were studied from 1993 to 1996 by radiotracking a free-living population of wild rabbits. During the three months after immunisation, unvaccinated young rabbits weighing between 180 and 600 g were 13.6 times more likely to die than vaccinat...

Interpretation of Serologic Test Results and Evaluation of Humoral Immune Response After Vaccination Following Infection with COVID-19 Disease

SARS-CoV-2 virus infection induces a cellular and humoral mediated immune response and produces antibodies against viral antigens such as nucleocapsid (N) protein and spike (S) protein. Anti-protein S antibodies also target the spike protein subunit S1 and the receptor binding domain (RBD). Serologic tests can detect the presence of these antibodies in blood serum within a few days to a few wee...

Incidence, epizootiology and control of viral haemorrhagic disease of rabbits and the European brown hare syndrome in Germany.

Viral haemorrhagic disease (VHD) among domestic and wild rabbits and European brown hares have been observed in most of the Federal states of Germany. Acute outbreaks of viral haemorrhagic disease are most prevalent in small, fancy domestic rabbitries, with mortality varying between 5 and 90%, while mostly sporadic losses due to VHD are seen among wild rabbits. In hares, accumulated losses from...
