Vaccine court
The VICP covers all vaccines listed on the Vaccine Injury Table maintained by the Secretary of Health and Human Services; in 2007 the list included vaccines against diphtheria, tetanus, pertussis (whooping cough), measles, mumps, rubella (German measles), polio, hepatitis B, varicella (chicken pox), "Haemophilus influenzae" type b, rotavirus, and pneumonia. From 1988 until 8 January 2008, 5,263 claims relating to autism, and 2,865 non-autism claims, were made to the VICP. 925 of these claims, one autism-related (see previous rulings), were compensated, with 1,158 non-autism and 350 autism claims dismissed; awards (including attorney's fees) totaled $847 million. The VICP also applies to claims for injuries suffered before 1988; there were 4,264 of these claims of which 1,189 were compensated with awards totaling $903 million.
Thymidine kinase
After smallpox was declared eradicated by WHO in December 1979, vaccination programs were terminated. A re-emergence of the disease either by accident or as a result of biological warfare would meet an unprotected population and could result in an epidemic that could be difficult to control. Mass vaccination would be unethical, as the only efficient vaccines against smallpox include live vaccinia virus with severe adverse effects on rare occasions. As one protective measure, large amounts of vaccine are kept in stock, but an efficient drug against smallpox has high priority. One possible approach would be to use the specificity of the thymidine kinase of poxvirus for the purpose, in a similar way that it is used for drugs against herpesvirus. One difficulty is that the poxvirus thymidine kinase belongs to the same family of thymidine kinases as the human thymidine kinases and thereby is more similar chemically. The structure of poxvirus thymidine kinases has therefore been determined to find potential antiviral drugs. The search has, however, not yet resulted in a usable antiviral drug against poxviruses.
