Evidence for Residual Immunity to Smallpox After Vaccination and Implications for Re-emergence

Smallpox: residual antibody after vaccination.

Of all the microorganisms and toxins, poxviruses (Orthopoxvirus) have the greatest potential for use by terrorists. These viruses can spread rapidly through the environment following initial infection. In 1980, the World Health Organization Eradication Program discontinued vaccination for smallpox and declared that the disease had been eliminated. With the threat of smallpox virus as a bioterro...

Duration of immunity after smallpox vaccination: a study on vaccination policy against smallpox bioterrorism in Japan.

The success of global smallpox eradication in 1980 led all the nations of the world to discontinue smallpox vaccination. To date, however, the threat of deliberate release of smallpox virus has led health authorities to reconsider smallpox vaccination and at the same time, to urge to evaluate duration of the immunity of the population vaccinated before 1980. Although available data is scarce an...

Physiological and Pathological Roles for MicroRNAs: Implications for Immunity Complications

MicroRNAs (miRNAs) are small non-coding regulatory RNAs molecules with a size of approximately 22 nucleotides that are implicated in regulating gene expression at the post-transcriptional regulatory levels. Inflammatory disorders especially autoimmune diseases (ADs) occur from an abnormal immune response of body against cells of their own specific tissues or multiple organ systems leading to ch...
