COVID Vaccine Could Affect Sharks

The video discusses the environmental impact of using shark liver oil, known as squalene, in COVID vaccines. It highlights the potential threat to shark populations, as many vaccine candidates use this oil. Alternatives like olive oil and sugar cane are available but are more costly. Conservationists fear that up to half a million sharks could be killed due to this demand.

What are some vaccines that also use squalling derived from shark livers?

Why do conservationists admit that non-animal sources of squalling are more expensive?
