Bovine ephemeral fever ( BEF) also known as Three Day Sickness is an arthropod vector-borne disease of cattle and is caused by bovine ephemeral fever virus (BEFV), a member of the genus Ephemerovirus in the family Rhabdoviridae .
Vaccinia. Vaccinia virus ( VACV or VV) is a large, complex, enveloped virus belonging to the poxvirus family. [2] It has a linear, double-stranded DNA genome approximately 190 kbp in length, which encodes approximately 250 genes. The dimensions of the virion are roughly 360 × 270 × 250 nm, with a mass of approximately 5–10 fg. [3]
Attenuated vaccine. An attenuated vaccine (or a live attenuated vaccine, LAV) is a vaccine created by reducing the virulence of a pathogen, but still keeping it viable (or "live"). [1] Attenuation takes an infectious agent and alters it so that it becomes harmless or less virulent. [2] These vaccines contrast to those produced by "killing" the ...
A viral vector vaccine is a vaccine that uses a viral vector to deliver genetic material ( DNA) that can be transcribed by the recipient's host cells as mRNA coding for a desired protein, or antigen, to elicit an immune response. [1] As of April 2021, six viral vector vaccines, four COVID-19 vaccines and two Ebola vaccines, have been authorized ...
1926 – First vaccine for pertussis (whooping cough) by Leila Denmark. 1932 – First vaccine for yellow fever by Max Theiler and Jean Laigret. 1937 – First vaccine for typhus by Rudolf Weigl, Ludwik Fleck and Hans Zinsser. 1937 – First vaccine for influenza by Anatol Smorodintsev [11] 1940 – First vaccine for anthrax.
A conjugate vaccine is a type of subunit vaccine which combines a weak antigen with a strong antigen as a carrier so that the immune system has a stronger response to the weak antigen. Vaccines are used to prevent diseases by invoking an immune response to an antigen, part of a bacterium or virus that the immune system recognizes. [2]
t. e. A H5N1 vaccine is an influenza vaccine intended to provide immunization to influenza A virus subtype H5N1 . Vaccines have been formulated against several of the avian H5N1 influenza varieties. Vaccination of poultry against the H5N1 epizootic is widespread in certain countries. Some vaccines also exist for use in humans, and others are in ...
