Precautions are taken to avoid contact with the skin and any fluids exuded through natural body openings of a deceased body that is suspected of harboring<unk> . The body should be put in strict quarantine. A blood sample is collected and sealed in a container and analyzed in an approved laboratory to ascertain if<unk>  is the cause of death. The body should be sealed in an airtight body bag and incinerated to prevent the transmission of<unk>  spores. Microscopic visualization of the encapsulated bacilli, usually in very large numbers, in a blood smear stained with polychrome methylene blue (McFadyean stain) is fully diagnostic, though the culture of the organism is still the gold standard for diagnosis. Full isolation of the body is important to prevent possible contamination of others. Protective, impermeable clothing and equipment such as rubber gloves, rubber apron, and rubber boots with no perforations are used when handling the body. No skin, especially if it has any wounds or scratches, should be exposed. Disposable personal protective equipment is preferable, but if not available, decontamination can be achieved by autoclaving. Used disposable equipment is burned and/or buried after use. All contaminated bedding or clothing is isolated in double plastic bags and treated as biohazard waste. Respiratory equipment capable of filtering small particles, such the US National Institute for Occupational Safety and Health- and Mine Safety and Health Administration-approved high-efficiency respirator, is worn. Vaccines Vaccines against<unk>  for use in livestock and humans have had a prominent place in the history of medicine. The French scientist Louis Pasteur developed the first effective vaccine in 1881. Human<unk>  vaccines were developed by the Soviet Union in the late 1930s and in the US and UK in the 1950s. The current FDA-approved US vaccine was formulated in the 1960s. Currently administered human<unk>  vaccines include acellular (United States) and live vaccine (Russia) varieties. All currently used<unk>  vaccines show considerable local and general reactogenicity (erythema, induration, soreness, fever) and serious adverse reactions occur in about 1% of recipients. The American product, BioThrax, is licensed by the FDA and was formerly administered in a six-dose primary series at 0, 2, 4 weeks and 6, 12, 18 months, with annual boosters to maintain immunity. In 2008, the FDA approved omitting the week-2 dose, resulting in the currently recommended five-dose series. New second-generation vaccines currently being researched include recombinant live vaccines and recombinant subunit vaccines. In the 20th century the use of a modern product (BioThrax) to protect American troops against the use of<unk>  in biological warfare was controversial. Antibiotics Preventive antibiotics are recommended in those who have been exposed. Early detection of sources of<unk>  infection can allow preventive measures to be taken. In response to the<unk>  attacks of October 2001, the United States Postal Service (USPS) installed biodetection systems (BDSs) in their large-scale mail processing facilities. BDS response plans were formulated by the USPS in conjunction with local responders including fire, police, hospitals, and public health. Employees of these facilities have been educated about<unk> , response actions, and prophylactic medication. Because of the time delay inherent in getting final verification that<unk>  has been used, prophylactic antibiotic treatment of possibly exposed personnel must be started as soon as possible.
