Almost 18,000 cases of swine flu and 45 confirmed deaths have been reported within the U.S. As the swine flu runs its course, Health and Human Services Secretary Kathleen Sebelius has reported that vaccines for swine flu are currently being tested in preparation for the possibility of an outbreak later this year. She stated that the government is making every effort to be prepared and is working with governors and health and school officials in case a major vaccination program is needed.
