A vaccine is available for horses. [1] This vaccine is an inactivated vaccine that uses the TC-83 strain of EEEV. [ 13 ] It is usually given in combination with vaccines for Western equine encephalitis (WEE), Venezuelan equine encephalitis (VEE), and tetanus , [ 4 ] and is also used by laboratory workers to protect from accidental exposure.
Vaccination [ edit ] In the journal Parasite Immunology , Kamal et al. explains that parasitic worms often weaken the immune system's ability to effectively respond to a vaccine because such worms induce a Th2-based immune response that is less responsive than normal to antigens. [ 20 ]
Equine encephalosis virus is an Orbivirus, and as such encodes 4 non-structural and 7 structural proteins derived from 10 linear dsRNA genome segments. [6] The smallest of those genome segments, segment-10, encodes the NS3 protein, which allows the release of the viral particles from the infected cell. [4]
Unlike Eastern equine encephalitis, the overall mortality of WEE is low (approximately 4%) and is associated mostly with infection in the elderly. Approximately 15–20% of horses that acquire the virus will die or be put down. [3] There is no human vaccine for WEE and there are no licensed therapeutic drugs in the U.S. for this infection.
Venezuelan equine encephalitis virus is a mosquito-borne viral pathogen that causes Venezuelan equine encephalitis or encephalomyelitis (VEE). VEE can affect all equine species, such as horses, donkeys, and zebras. After infection, equines may suddenly die or show progressive central nervous system disorders. Humans also can contract this disease.
The current vaccine includes a flu B strain, which can surge later in the season, so it can offer continued protection. You can take other simple actions to help prevent flu. "Flex those pandemic ...
