Drug companies stand to profit from H1N1 scare

The H1N1 flu virus can be deadly for sufferers but it is giving some giant drug companies a healthy cash injection.

In the United States 250 million doses of the newly developed vaccines will be distributed, and that means there is a lot of money to be made by drug companies.

Al Jazeera's Dan Nolan reports on the host of companies and groups making a profit from tackling the virus.
