BACKGROUND Control of classical swine fever (CSF) by vaccination ideally requires that field strain infection can be detected irrespective of the vaccination status of the herd. To inform on the usefulness of molecular tests compatible with genetic Differentiation of Infected from Vaccinated Animals (DIVA) principles when using live-attenuated vaccines, tonsil homogenates from a vaccination-cha...

Vaccination has been used for the prevention and eradication of communicable diseases such as smallpox, polio, measles. Herd immunity threshold have already conceptualized outbreaks pandemicity these diseases. Coronavirus infectious disease-19 (COVID-19) is second pandemic coronavirus disease 21st century. conducted since December 2020 in an attempt to control pandemic. The morbidity incidence ...

Genetic resistance to avian tumor virus-induced tumorigenesis and vaccine protective efficacy preventing such tumorigenicity are determined by multiple factors including host genetics, viral virulence, dose of challenge viruses, type of vaccine, vaccine dosage, and interval between vaccination and viral exposure time. Studies on human immune response to vaccination suggest host genetic variabil...

considering the circulation of bordetella pertussis clinical strains among populations with high vaccination coverage, it is necessary to have a proper understanding of this bacterium causing whooping cough. various techniques, which are available for studying b. pertussis, can facilitate a proper comparison between different populations. we genotypically analyzed a collection of two vaccine st...

OBJECTIVES To analyse serogroup (Sg)- and finetype-specific invasive meningococcal disease burden (IMD) in Germany, 2002-2010, with emphasis on effects of vaccination with conjugate SgC vaccines targeting one-year old children since 2006, including individual-based catch-up to 17 years of age. METHODS Serogroup- and age-specific IMD incidence and trends were calculated using statutory surveil...

Vaccinations have been used as an essential tool in the fight against infectious diseases, and succeeded in improving public health. However, adverse effects, including autoimmune conditions may occur following vaccinations (autoimmune/inflammatory syndrome induced by adjuvants--ASIA syndrome). It has been postulated that autoimmunity could be triggered or enhanced by the vaccine immunogen cont...

Virion host shutoff (vhs)-deficient herpes simplex virus (HSV) was tested as a therapeutic vaccine in a mouse model of UV light-induced recurrent herpetic stromal keratitis. Four weeks after primary corneal infection, mice were vaccinated intraperitoneally with vhs(-) vaccine or control. Four weeks after vaccination, the eyes of latently infected mice were UV-B irradiated to induce recurrent vi...

BACKGROUND Immunization of mice with the Trypanosoma cruzi trans-sialidase (TS) gene using plasmid DNA, adenoviral vector, and CpG-adjuvanted protein delivery has proven highly immunogenic and provides protection against acute lethal challenge. However, long-term protection induced by TS DNA vaccines has not been reported. The goal of the present work was to test whether the co-administration o...
