VARIOLA VACCINIA Meaning and
Definition
-
Variola vaccinia, commonly referred to as vaccinia, is a virus belonging to the Poxviridae family and the Orthopoxvirus genus. It is an attenuated strain of the variola virus, which is responsible for causing smallpox. The term "vaccinia" is derived from the Latin word "vacca," meaning cow, as it was first isolated from cows.
Vaccinia is used as a live virus vaccine to protect individuals against smallpox. This vaccine, known as the smallpox vaccine, induces an immune response that provides immunity to the variola virus. The virus is usually administered by a technique known as scarification, wherein the vaccine is applied to the skin using a bifurcated needle. The site of vaccination forms a characteristic lesion known as a pock or a vesicle, which eventually scabs over and leads to the formation of a scar.
The variola vaccinia virus closely resembles the variola virus but is less virulent, meaning it produces a milder infection. However, certain individuals, especially those with compromised immune systems, may experience adverse side effects, including a potentially life-threatening condition known as eczema vaccinatum. Additionally, accidental transfer of the virus to the eyes or other parts of the body may develop into serious complications.
In conclusion, variola vaccinia is an attenuated strain of the variola virus used as a live virus vaccine against smallpox. Its administration induces an immune response that protects against the smallpox virus, although certain risks and complications may arise.
