Question 5

For years, the residents of a small Mexican town complained about the filth from a nearby hog farm, where millions of pigs are raised each year. In 2009, the majority of residents in this town became sick with ʺswine flu,ʺ caused by the H1N1 influenza virus. This virus infects people but is apparently genetically similar to a virus that infects hogs. The virus has since gone on to infect (and, in some cases, kill) people in Mexico City, and has quickly spread around the entire planet. The ʺswine fluʺ has been declared a global pandemic. Based on this scenario and your knowledge of genetics, what is a potential technique that could be used to prevent this disease?
