How the Swine Flu vaccines are made

The amount of viral particles obtained from incubated eggs is crucial. If pharmaceutical companies like Glaxo-Smithkline who manufacture the vaccines find that they get less than expected from each egg, this could drastically effect the amount available to the public. So far no one is sure how much swine flu vaccine can be grown in each egg.

After the viruses are extracted from the eggs they are broken up into pieces. Splitting them ensures that the protein coat of the viruses is on display so that it can induce an immune response in humans. Antibodies are normally formed in the blood as a direct response to foreign protein particles. These protein particles will be similar to those present on a real live swine flu virus. Therefore a vaccine prepares the immune system for a possible invasion. Enabling the immune system to prepare is what makes a vaccine so powerful.
