Swine flu vaccine made by killing sharks

Reports indicate that vaccines being made to protect people from swine flu are developed by killing sharks, thus endangering the animals further.

According to a report in National Geographic News, millions of doses of the pandemic H1N1/09 vaccine contain a substance called squalene, which is extracted from shark livers.

More commonly found in beauty products such as skin creams, squalene can be used to make an adjuvant, a compound that boosts the body’s immune response.

The World Health Organization (WHO) recommends adjuvant-based vaccines, because they allow drug makers to create doses that use less of the active component, increasing available supplies.

Olive oil, wheat germ oil, and rice bran oil also naturally contain squalene, albeit in smaller amounts.

But for now, squalene is primarily harvested from sharks caught by commercial fishers, especially deepwater species.

There are several very disturbing issues associated with use of shark-liver-oil squalene,” said Mary O’Malley, co-founder of the volunteer-run advocacy group Shark Safe Network.

“The deepwater sharks targeted have extremely low reproductive rates, and many are threatened species,” she added.

For example, one supplier has dubbed the gulper shark the Rolls-Royce of squalene-producing sharks, but the gulper is listed as vulnerable on the International Union for Conservation of Nature’s (IUCN’s) Red List of Threatened Species, meaning the species faces a high risk of extinction.
