To eliminate incursions of foot-and-mouth disease (FMD) quickly, a combination of measures, including emergency vaccination, can help block the spread of infection. For the earliest recovery of the FMD-free status for trade, without the slaughter of uninfected vaccinated animals, a serosurvey for antibodies to FMD virus non-structural proteins (NSP) must be used to substantiate absence of occult virus...
The development of safe, effective, and affordable vaccines has become a global effort due to its vast impact on overall world health conditions. A brief overview of vaccine characterization techniques, especially in the area of high-resolution mass spectrometry, is presented. It is highly conceivable that the proper use of advanced technologies such as high-resolution mass spectrometry, along with...
The level of protection conferred by foot-and-mouth disease (FMD) vaccines in primovaccinated animals primarily depends on the potency of the vaccine and the relatedness of the vaccine strain and circulating field isolate. The “Gold Standard” FMD vaccine potency test is the in vivo test performed in the target species. The objective of the study was to determine the precision of the in vivo “Protection...
The diagnostic performance of six foot-and-mouth disease (FMD) assays for detection of antibodies to the non-structural proteins (NSP) of the FMD virus (FMDV) was estimated using a Bayesian analysis on field sera from cattle of unknown infection status originating from post-FMDV outbreak situations in Israel and Zimbabwe. Estimations of the disease prevalence in both populations were also obtained...
In the event of a foot-and-mouth (FMD) outbreak in a densely populated livestock area within the European Community, emergency vaccination will most likely be employed. The objective of the present study was to support the European FMD control policy by evaluating the between test variability of the European accepted method for assessing the potency, a major determinant in vaccine choice, of an FMD...
To validate the use of serology in substantiating freedom from infection after foot-and-mouth disease (FMD) outbreaks have been controlled by measures that include vaccination, 3551 sera were tested with six assays that detect antibodies to the non-structural proteins of FMD virus. The sera came from naïve, vaccinated, infected and vaccinated-and-infected animals; two-thirds from cattle, the remainder...
We aimed to describe the impact of vaccination on the epidemiology of measles infection in Flanders (Belgium), to document probable vaccination coverage based on this evidence, compare these epidemiological data with those generated by a mathematical model and estimate the costs of morbidity from measles. In contrast to previous analyses, we included the costs of long-term care for sequelae due to...
