Resolved Question: How do you think a pig virus got into the recalled rotavirus pediatric vaccine?

Here is the news on this:  http://news.yahoo.com/s/ap/20100322/ap_on_he_me/us_med_vaccine_warning http://www.fda.gov/NewsEvents/PublicHealthFocus/ucm205585.htm  From what I understand, this vaccine was cultured in monkey cells, not pig cells, so it is a big mystery to me as to how a pig virus could have contaminated the vaccines.  You would expect a contaminant to be a monkey virus like the SV40 that contaminated polio vaccines years ago.  http://www.youtube.com/watch?v=oQ1akBtmo7A http://www.sv40foundation.org/  The sources below could offer an explanation, though, since they describe rampant contamination and mislabeling of cell cultures used in research and vaccine development.  But I would expect a vaccine manufacturer to verify cell cultures before using them, so this still seems very unusual.  http://cellbank.nibio.go.jp/cellbank/qualitycontrol/OL7-11-07.pdf http://digitalmedia.cua.edu//events/video/asx_dsp.cfm?event=4062&stream=4364
