Why is our vaccine made in the UK and not the US?

The major pharmaceutical companies in the US provided almost
90% of the nations flu vaccine at one time. They did this
despite a very low profit margin for the product. Basically,
they were doing us a favor. In the late 80's a man from
North Carolina who had received the vaccine got the flu. The
strain he caught was one of the strains in that years
vaccine made by a US company. What did he do? He sued and he
won. He was awarded almost $5 million! After that case was
appealed and lost, most US pharmaceutical companies stopped
making the vaccine. The liability out weighed the profit
margin. Since UK and Canadian laws prohibit such frivolous
law suits UK and Canadian companies began selling the
vaccine in the US.
