A Coronavirus Vaccine Could Kill Half A Million Sharks, Conservationists Warn

NATIONAL PUBLIC RADIO • October 10, 2020

Squalene, a compound that is harvested from the livers of sharks, is a common moisturizing ingredient in cosmetics. It's also used in malaria and flu vaccines as an agent that boosts the immune system's response. Shark Allies, a nonprofit that advocates for the protection of sharks, projects that some 500,000 sharks could be killed if a coronavirus vaccine with shark squalene proves to be effective. Already, an estimated 2.7 million sharks are killed annually for their squalene to make cosmetics, according to the group.
