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.
He has grave reservations about the firm Novartis who are developing the vaccine and testing it in Germany. The vaccination is injected “with a very hot needle”, Wodarg said.
The nutrient solution for the vaccine consists of cancerous cells from animals and "we do not know if there could be an allergic reaction".
But more importantly, some people fear that the risk of cancer could be increased by injecting the cells.
