Children receiving smallpox, measles, and yellow fever vaccines simultaneously at separate sites responded adequately to all three vaccines. In those children, 9 months of age and older, who received these three vaccines in addition to diphtheria-pertussis-tetanus vaccine, there was a decrease in
The threat of bioterrorism with use of viruses is increasing. Smallpox, encephalitis, and hemorrhagic fevers are the most likely diseases to result from viral deployment. It is critical that all healthcare professionals become familiar with the clinical presentation, diagnosis, management, and
BACKGROUND
Establishment of immunological memory is a hallmark of adaptive immune responses and the biological mechanism for the success of vaccines. However, in humans, much of our knowledge about adaptive immune responses derives from studies of chronic viral infections.
OBJECTIVE
Here, we
CDC designated category A infectious agents pose a major risk to national security and require special action for public health preparedness. They include viruses that cause viral hemorrhagic fever (VHF) syndrome as well as variola virus, the agent of smallpox. VHF is characterized by hemorrhage and
Brucella, Q fever, tularemia, and smallpox are all rare infections in the United States but are potential agents of biologic terrorism. The pulmonary manifestations of these infections range from uncommon (brucella and smallpox) to expected (Q fever and tularemia). and all have clinical and
BACKGROUND
the search for effective inhibitors to multiple infectious agents including influenza, smallpox and hemorrhagic fever viruses is an area of active research as many of these agents pose dramatic health and economic challenges to the human population. Many of these infectious agents are not
An earlier study established that Upper Volta children respond to vaccination with the Enders live attenuated measles strain in the same general fashion as do children in the USA. The present report describes a second pilot project carried out in Ouagadougou, Upper Volta. During this investigation
The US cases of anthrax in 2001 and the recent severe acute respiratory syndrome outbreak have heightened the need for preparedness and response to naturally emerging and re-emerging infections or deliberately released biological agents. This report describes the response model of the Istituto
The US cases of anthrax in 2001 and the recent severe acute respiratory syndrome outbreak have heightened the need for preparedness and response to naturally emerging and re-emerging infections or deliberately released biological agents. This report describes the response model of the Istituto
To explore the human T cell response to acute viral infection, we performed a longitudinal analysis of CD8(+) T cells responding to the live yellow fever virus and smallpox vaccines--two highly successful human vaccines. Our results show that both vaccines generated a brisk primary effector CD8(+) T
Live virus vaccines provide a unique opportunity to study human CD8(+) T-cell memory in the context of a controlled, primary acute viral infection. Yellow fever virus-17D and Dryvax are two such live-virus vaccines that are highly efficacious, used worldwide and provide long-term immunity against
