In 2000, CDC awarded a contract to Acambis of Cambridge, Massachusetts to produce smallpox vaccine. Initially producing 40 million doses, Acambis anticipates delivery of the first full scale production lots in 2004Acambis can confirm that this programme has been accelerated but is unable to give more details at this stage.

The only known effective prevention against anthrax is the anthrax vaccine. The vaccine was developed from an attenuated strain of B. anthracis. The vaccine derives from the cell-free culture filtrate of this strain and, in its final formulation, is adsorbed onto an aluminum salt. No cases of inhalation anthrax occurred in anthrax vaccine recipients. Based upon a comparison between the anthrax vaccine and placebo recipients, the authors calculated a vaccine efficacy level of 92.5 percent.

The focus of the hearing was on a recent terrorism response exercise ominously named Dark Winter during which the unimaginable had to be imagined: a multi-site smallpox attack on an unvaccinated American populace. The scenario called upon those playing the president, the National Security Council and state officials to deal with the crippling consequences of what quickly became a massive public health and national security crisis.

Influenza, commonly called "the flu," is an infection of the respiratory tract caused by the influenza virus. Compared with most other viral respiratory infections, such as the common cold, influenza infection often causes a more severe illness. Typical influenza illness includes fever (usually 100ºF to 103ºF in adults and often even higher in children) and respiratory symptoms, such as cough, sore throat, runny or stuffy nose, as well as headache, muscle aches, and often extreme fatigue. Although nausea, vomiting, and diarrhea can sometimes accompany influenza infection, especially in children, these symptoms are rarely the primary symptoms.

Mosquitoes are a very important insect pest affecting the health of humans because of their ability to transmit diseases. Virginia has 55 different known species of mosquitoes. There are approximately 30 different kinds of mosquitoes in Fairfax County. Fairfax health officials are asking residents to be more conscious of the need to eliminate mosquito breeding places around their homes. Health officials encourage residents to be on the lookout for small pools of water in rain gutters, discarded tires, tarps covering firewood, toys,pet water bowls,flower pots,bird baths, etc., which could be breeding grounds for mosquitoes. Taking away or regular emptying of those potential mosquito breeding sites around the home will help limit the number of pesky mosquitoes and help reduce the mosquito population.

These results clearly indicate that the very conservative estimated risks from DU inhalation are less than the guidelines for members of the public. They also provide perspective on the requirements for respiratory protection around contaminated vehicles. A Gulf War-era technical bulletin recommended wearing MOPP 4 (Mission Oriented Protective Posture [MOPP] Level 4) because it was readily available to all soldiers. Most soldiers and civilians were not trained in DU�s characteristics and risks and were unaware of this protective guidance. taking 20 minutes to pass one burning Abrams Heavy Armor tank; entering 7 enemy vehicles hit by DU and spending 7 minutes in each vehicle without contaminating his hands; entering one enemy vehicle for one hour, contaminating his uncovered hands, which he then did not wash for two days; and taking 10 minutes to pass at a distance of 80 meters through the smoke of 3 burning enemy tanks struck by DU.
