The US vaccination shortage has been caused by the discovery of bacterial contamination in supplies of vaccine produced by Chiron at their plant based
in Liverpool, UK. The San Francisco Chronicle is amongst sources that are reporting that the contaminating bacteria has been identified as Serratia
marcescens, an opportunistic pathogen.
Americans may never know how close a Bay Area company came to distributing a bacteria-tainted flu vaccine, or how much of that vaccine was
What is known is that the bacteria that ruined the stockpile of vaccine produced by Chiron Corp. was used in a secret germ-warfare experiment in the
Bay Area conducted by the Army and was tied to three deaths in Contra Costa County in 2001.

The bacteria was used extensively by the US Government as a Biological Warfare simulant. A BW simulant is a harmless substance which mimics the
actions of a pathogen, and is used in BW experiments where it would be impractical to use a pathogenic, or disease causing, organism.
The most well known seriexs of experiments which used Serratia marcescens as a simulant was the 1950 spraying of San Francisco by the US Army. The
clandestine tests were designed to see if a sabotage BW attack could be made on a city. The US Government were later unsuccessfully sued by a San
Francisico family who blamed the tests for the death of a family member, Edward Nevin.
Serratia marcescens remained in use as an aerobiologic tracer organism for many years and is still in use even after being recognised as an
Given Serratia marcescens history as an aerobiological tracer organism, it's not too big a leap of the imagination to question whether it had
recently been used to test the airflow of the vaccine production plant, thus inadvertently causing the contamination.
This organism was, and possibly still is, used in hospitals in order to trace sources and pathways of acquired infection.
