<P> Conspiracy theorist Alan Krumwiede (Jude Law) posts videos about the virus on his popular blog . In one video, he shows himself sick and later claims he recovered using a homeopathic cure derived from forsythia . In a panic, people seeking forsythia overwhelm pharmacies, spreading and accelerating the contagion as the infected come into contact with healthy people . </P> <P> Krumwiede's claims attract national attention . During a television interview he discloses that Dr. Cheever had secretly informed friends and family to leave Chicago just before the city was quarantined . Cheever is then informed the government will investigate and may charge him for leaking information . Later it is revealed Krumwiede had faked being infected by the virus in an attempt to increase profits for shareholders in companies producing and selling forsythia . Krumwiede is arrested for conspiracy and securities fraud, only to walk free when his many supporters successfully raise funds to provide for his bail . </P> <P> Using an attenuated virus Dr. Hextall identifies a possible vaccine . To cut out the lengthy time it would take to obtain informed consent from infected patients, Dr. Hextall inoculates herself with the experimental vaccine and immediately visits her gravely ill father (Dan Flannery), who has been infected with MEV - 1 . The doctor does not contract MEV - 1 and the vaccine is declared a success . </P> <P> The vaccine's production is rapidly increased, but due to limited production, the CDC awards vaccinations by lottery based on birth date . Inoculations take place for one full year until every survivor is vaccinated . First responders, doctors and others designated by the government are declared exempt from the lottery . Dr. Cheever gives his fast - tracked MEV - 1 vaccination to the son of Roger (John Hawkes), a CDC janitor who had overheard Dr. Cheever's phone call warning his girlfriend to leave Chicago . </P>
