There are two versions of H1N1 or Swine Flu vaccine being prepared for this fall flu season. At least two of them are "Live Virus" Vaccines.

MedImmune, part of global drugmaker AstraZeneca, is one of five companies with a contract to sell a vaccine for the H1N1 virus, originally known as swine flu, to the federal government. MedImmune's flu vaccine differs from the others in two major ways: It is delivered via nasal spray instead of an injection and is made with a live but weakened virus instead of a dead one.

The U.S. government signed contracts with four companies worth a total of almost $1 billion to purchase ingredients used to make vaccines against the new H1N1 influenza virus. The funds will be used to place additional orders for bulk H1N1 antigen and adjuvant on existing contracts with U.S. units of Sanofi-Aventis SA and AstraZeneca PlC, along with GlaxoSmithKline PlC and Novartis AG.
