VACCINE PRODUCTION Like traditional seasonal flu vaccines, the GSK swine flu vaccine is being made in eggsThe H1N1 strain is injected into eggs where it multiples before being harvested, purified and chemically inactivated so it cannot cause flu but can prompt an immune responseThe resulting viral particles are then tested and added to the vaccineIt can take up to two eggs to produce one dose of vaccineThe other method for making vaccines uses mammalian cell cultures to grow the vaccine - this is the approach being taken by BaxterVACCINE PRODUCTION Like traditional seasonal flu vaccines, the GSK swine flu vaccine is being made in eggsThe H1N1 strain is injected into eggs where it multiples before being harvested, purified and chemically inactivated so it cannot cause flu but can prompt an immune responseThe resulting viral particles are then tested and added to the vaccineIt can take up to two eggs to produce one dose of vaccineThe other method for making vaccines uses mammalian cell cultures to grow the vaccine - this is the approach being taken by Baxter

WHY TWO VACCINES? The UK has agreed contracts for swine flu vaccine with GSK and BaxterHaving two contracts increases the number of doses availableAlso because the Baxter vaccine is not made in eggs it can be used in people with an egg allergyThere are other differences between the vaccines -for example the GSK one contains an adjuvantIt minimises the risk of problems should one vaccine run into trouble during production or licensingWHY TWO VACCINES?
