The Relation Antibody and Protection after Foot-and-mouth Disease Vaccination Cannot Be Standardised
Many studies have been performed into the relation antibody response and protection after footand-mouth disease (FMD) vaccination (Black et al. 1984; Pay et al. 1987; Pay et al. 1992). In every study a correlation was observed with the antibodies induced by the vaccine used in the study and protection observed after challenge. In the studies the methodology was never the same, e.g. the type of ...
Foot-and-mouth disease (FMD) is a highly contagious and economically devastating disease of cloven-hoofed animals in the world. The disease can be effectively controlled by vaccination of susceptible animals with the conventional inactivated vaccine. However, one major concern of the inactivated FMD virus (FMDV) vaccine is that it does not allow serological discrimination between infected and v...
UNLABELLED Foot-and-mouth disease (FMD) is a highly contagious viral disease affecting biungulate species. Commercial vaccines, formulated with inactivated FMD virus (FMDV), are regularly used worldwide to control the disease. Here, we studied the generation of antibody responses in local lymphoid tissues along the respiratory system in vaccinated and further aerosol-infected cattle. Animals im...
Foot-and-mouth disease (FMD) is endemic in Pakistan and Afghanistan. The FMD virus serotypes O, A and Asia-1 are responsible for the outbreaks in these countries. Diverse strains of FMDV, even within the same serotype, co-circulate. Characterization of the viruses in circulation can facilitate appropriate vaccine selection and tracing of outbreaks. The present study characterized foot-and-mouth...
Countries that are free of foot and mouth disease (FMD) are reluctant to use vaccine in the event of an outbreak because of the difficulties this can cause in re-establishing freedom from FMD status to the satisfaction of trading partners. The problem does not lie in distinguishing between vaccinated and recovered animals as vaccinated animals can be tagged or otherwise marked to show that they...
Foot-and-mouth disease (FMD) endemic regions contain three-quarters of the world's FMD susceptible livestock and most of the world's poor livestock keepers. Yet FMD impact on smallholders in these regions is poorly understood. Diseases of low mortality can exert a large impact if incidence is high. Modelling and field studies commonly find high FMD incidence in endemic countries. Sero-surveys t...
The aim of this study was to investigate whether intradermal (ID) vaccination against foot-andmouth disease (FMD) is suitable as an alternative for the usually used intramuscular (IM) route. We used vaccines containing a normal or 10-fold dose antigen and compared groups of pigs that were vaccinated ID with either 0.2ml or 4x0.2ml with groups of pigs that were vaccinated IM with a standard 2ml,...
Changes to foot-and-mouth disease (FMD) control policies since 2001 mean that emergency vaccination must be considered more readily as a control measure in the future. Since field application of vaccine for emergency use has only rarely been applied, the effectiveness of single dose administration, as a control measure in an outbreak situation, is poorly understood. In this review we consider a...
