The need for more holistic immune profiling in next-generation SARS-CoV-2 vaccine trials

open access: yesFrontiers in Immunology, 2022
First-generation anit-SARS-CoV-2 vaccines were highly successful. They rapidly met an unforeseen emergency need, saved millions of lives, and simultaneously eased the burden on healthcare systems worldwide. The first-generation vaccines, however, focused

Genetically distinct pestiviruses pave the way to improved classical swine fever marker vaccine candidates based on the chimeric pestivirus concept

open access: yesEmerging Microbes and Infections, 2020
Classical swine fever (CSF) is one of the most important viral diseases of pigs. In many countries, the use of vaccines is restricted due to limitations of subunit vaccines with regard to efficacy and onset of protection as well as failure of live ...

Multiserotype protection elicited by a combinatorial prime-boost vaccination strategy against bluetongue virus. [PDF]

open access: yesPLoS ONE, 2012
Bluetongue virus (BTV) belongs to the genus Orbivirus within the family Reoviridae. The development of vector-based vaccines expressing conserved protective antigens results in increased immune activation and could reduce the number of multiserotype ...

Fluorescent-Antibody Marker for Vaccine-Induced Rubella Antibodies [PDF]

open access: yesInfection and Immunity, 1970
Tests with LLC-MK2 and BHK-21 cells showed that the fluorescent-antibody (FA) procedure can be used to differentiate antibodies resulting from natural infection and antibodies stimulated by rubella vaccine virus. Negative or weak FA reactions in LLC-MK2 cells and strong reactions in BHK-21 cells indicated antibody stimulated by the vaccine virus ...
