    Cowpox is an infectious disease caused by the cowpox virus (CPXV). [2] It presents with large blisters in the skin, a fever and swollen glands, historically typically following contact with an infected cow, though in the last several decades more often (though overall rarely) from infected cats. [3] The hands and face are most frequently ...

  2. Vaccinium myrtilloides is a shrub with common names including common blueberry, velvetleaf huckleberry, velvetleaf blueberry, Canadian blueberry, and sourtop blueberry. [2] It is common in much of North America, reported from all 10 Canadian provinces plus Nunavut and Northwest Territories, as well as from the northeastern and Great Lakes states in the United States.

    The traditional smallpox vaccine, which was used in the smallpox eradication campaign 1958–1977, consists of a live vaccinia virus which can replicate in humans but usually does not cause disease. It can however sometimes lead to serious side effects. Modified vaccinia Ankara virus is a highly attenuated strain of vaccinia virus that was developed ...

    Vaccinia viruses re-engineered to express foreign genes are vectors for production of recombinant proteins, the most common being a vaccine delivery system for antigens. A recombinant MVA-based vector for vaccination with different fluorescent reporter genes was developed, which indicate the progress of genetic recombination with the transgene of a...

    In animal models, MVA vaccines have been found to be immunogenic and protective against various infectious agents including immunodeficiency viruses, influenza, parainfluenza, measles virus, flaviviruses, tuberculosis, Plasmodium parasites as well as certain cancers. MVA-B is an experimental vaccine to protect against HIV infection, produced by ins...

    In addition to the morbidity of uncomplicated primary vaccination, transfer of infection to other sites by scratching, and post-vaccinial encephalitis, other complications of vaccinia infections may be divided into the following types:: 391 1. Generalized vaccinia 2. Eczema vaccinatum 3. Progressive vaccinia(vaccinia gangrenosum, vaccinia necrosum)...

    Vaccinia virus is closely related to the virus that causes cowpox; historically the two were often considered to be one and the same. The precise origin of vaccinia virus is unknown due to the lack of record-keeping, as the virus was repeatedly cultivated and passaged in research laboratories for many decades. The most common notion is that vaccini...

    Poxviruses are unique among DNA viruses because they replicate only in the cytoplasm of the host cell, outside of the nucleus. Therefore, the large genome is required for encoding various enzymes and proteins involved in viral DNA replication and gene transcription. During its replication cycle, VV produces four infectious forms which differ in the...

    Vaccinia virus is able to undergo multiplicity reactivation (MR). MR is the process by which two, or more, virus genomes containing otherwise lethal damage interact within an infected cell to form a viable virus genome. Abel found that vaccinia viruses exposed to doses of UV light sufficient to prevent progeny formation when single virus particles ...

    Vaccinia contains within its genome genes for several proteins that give the virus resistance to interferons: 1. K3L (P18378) is a protein with homology to the protein eukaryotic initiation factor 2 (eIF-2alpha). K3L protein inhibits the action of PKR, an activator of interferons. 2. E3L (P21605) is another protein encoded by Vaccinia. E3L also inh...

    Vaccinia virus infection is typically very mild and often does not cause symptoms in healthy individuals, although it may cause rash and fever. Immune responses generated from a vaccinia virus infection protects the person against a lethal smallpox infection. For this reason, vaccinia virus was, and still is, being used as a live-virus vaccine agai...

    The original vaccine for smallpox, and the origin of the idea of vaccination, was Cowpox, described by Edward Jenner in 1798. The Latin term used for Cowpox was Variolae vaccinae, Jenner's own translation of "smallpox of the cow". That term lent its name to the whole idea of vaccination. When it was realized that the virus used in smallpox vaccinat...

    In March 2007, a 2-year-old Indiana boy and his mother contracted a life-threatening vaccinia infection from the boy's father. The boy developed the telltale rash over 80 percent of his body after coming into close contact with his father, who was vaccinated for smallpox before being deployed overseas by the United States Army. The United States mi...

    Vaccaria segetalis (Neck.) Garcke ex Asch. Vaccaria is a monotypic genus of flowering plants in the family Caryophyllaceae containing the single species Vaccaria hispanica. It is known by several common names including cowherb, cowcockle, cow basil, cow soapwort, and prairie carnation. Its subspecies were previously treated as separate species.

  5. Vaccinium arboreum is a shrub (rarely a small tree) growing to 3–5 m (7.5-12.5 feet) rarely 9 m) (22.5 feet) tall, with a diameter at breast height of up to 35 cm (14 inches). The leaves are evergreen in the south of the range, but deciduous further north where winters are colder; they are oval-elliptic with an acute apex, 3–7 cm long and 2 ...

  6. Lifelong. Frequency. every 1 or 2 in a million during routine vaccination during 1963-1968 for smallpox. Deaths. fatality rate: 15%. Progressive vaccinia is a rare cutaneous condition caused by the vaccinia virus, characterized by painless, but progressive, necrosis and ulceration. [4]
