 +===How Do Vaccines Work===
 +
 +When inactivated or weakened disease-causing microorganisms enter the body, they initiate an immune response.  This response mimics the body’s natural response to infection. But unlike disease-causing organisms, vaccines  are made of components that have limited ability or are completely unable,to cause disease (See Figure 4).

 +
 +The 21-page implementation plan, released Apr 20 on the HHS Web site and in the Federal Register, details how the agency will **acquire countermeasures against 14 threats on its priority list**, which include nine category A biological agents, two category B biological agents, typhus, certain volatile nerve agents, and radiological and nuclear agents.

 ==== Vaccine Technological Development ==== ==== Vaccine Technological Development ====
 Vaccine development is generally a long process, taking years to design, hone, and test, in addition to feedback loops in that development process. Vaccine development is generally a long process, taking years to design, hone, and test, in addition to feedback loops in that development process.

 +===Vaccine Preservatives and Adjuvants===
 +
 +Vaccines may contain either or both preservatives and adjuvants these lists are incomplete.
 +
 +[[Preservatives]] may be used to prevent contamination of multi-dose containers: when a first dose of vaccine is extracted from a multi-dose container, a preservative will protect the remaining product from any bacteria  that may be introduced into the container. In some cases,preservatives may be added during manufacture to prevent microbial contamination. 
 +
 +Phenol Typhoid, pneumococcal polysaccharide
 +Benzethonium chloride [[Anthrax]]
 +2-phenoxyethanol [[Inactivated polio]]
 +[[Thimerosal]] Multi-dose influenza
 +
 +
 +[[Adjuvants]] enhance the immune effect of the vaccine [[antigen]], but do not themselves act as antigens.  [[Aluminum  salts]] are the mos  commonly used  adjuvant for vaccines. 
 +
 +**Aluminum Salts** [[Adjuvanted Vaccines]] - Hepatitis A, Hepatitis B, Diphtheria, Tetanus, acellular Pertussis combinations (DTaP orTdap), Pneumococcal conjugate,Japanese encephalitis
 +
 +**Aluminum salt or AS04 (aluminum salt and monophospholipid A)** [[Human Papilloma Virus]] 
 +(HPV)
 +**MF59 (oil in water emulsion) [one vaccine]**  H1N1 influenza
