Soo-Haeng works in a number of areas of operations management, including the use of OM methods in medical decisions.  He has a <a href=\"http:\/\/personal.anderson.ucla.edu\/soo-haeng.cho\/Assets\/S.%20Cho%20Paper%203.%20Vaccine%20Composition.pdf\">very nice paper<\/a> on choosing the correct flu  vaccine each year.   This issue has been in the news recently (including <a href=\"http:\/\/www.cnn.com\/2008\/HEALTH\/conditions\/02\/15\/flu.season.ap\/index.html\">CNN<\/a> ) because the current vaccine is missing quite a few of the flu bugs.  Cho&#8217;s paper talks about many of the issues that go into the choice of vaccine, not all of which are reasonably covered by the popular press.  In particular, I hadn&#8217;t realized the strong advantage of doing the same as last year in terms of getting reliable vaccines out to people.\u00a0 From his paper:<\/p>\n<blockquote><p>The production yields of strains are variable and unknown owing to its biological characteristic (Matthews 2006). Moreover, yield uncertainty is increased significantly when a vaccine strain is changed. The magnitude of this challenge is illustrated in the following quote from an industry representative (Committee<br \/>\n2003):<br \/>\n\u201ccertainly the best way to ensure this predictability of supply is not to recommend any [strain] changes, &#8230; a second best way is to minimize the number of strain changes. Each new strain can yield anywhere from 50 to 120 percent of the average strain.\u201d<br \/>\nThus, even if a new virus strain is predominant, a change is made only when the benefit from improved efficacy outweighs the risk associated with making the change in production. For instance, although new A\/Fujian-like virus strains were widely spreading during the 2002-3 season, the Committee did not select<br \/>\nthat strain because it was not suitable for large-scale manufacturing.<\/p><\/blockquote>\n<p>It is clear that understanding the medical decision making requires the understanding of manufacturing operations, which I think is a great theme in the upcoming years for our field.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I&#8217;ve been back in the US for about six weeks now, and am getting used to being back in my academic life.
