The swine flu vaccine has been hit by new cancer fears after a German health expert gave a shock warning about its safety.
Lung specialist Wolfgang Wodarg has said that there are many risks associated with the vaccine for the H1N1 virus. The nutrient solution for the vaccine consists of cancerous cells from animals, and some fear that the risk of cancer could be increased by injecting the cells.
The vaccine can also cause worse side effects than the actual swine flu virus.
