Squalene, an organic compound harvested from shark livers, is used in a variety of areas, including pharmacology. It is the main ingredient in adjuvants, which are used to improve immune system responses to vaccines. Squalene-based adjuvants are currently used in vaccines to prevent different strains of influenza and coronaviruses.
Up to 500,000 sharks could be killed in order to produce a coronavirus vaccine, warned Shark Allies, a nonprofit organisation dedicated to restoring and preserving the shark population. The group’s estimates suggest that in order to vaccinate the world’s population with one inoculation for COVID-19, around 250,000 sharks would need to be killed. Given that previous studies said people would need two doses of the COVID-19 vaccine to develop an immune response, means that half a million of sharks could be killed to rid humanity of COVID-19.
Greedy Pharma
Shark Allies notes that many shark species, such as the gulper shark and basking shark have been classified as vulnerable, meaning their populations are decreasing. The group notes that the use of squalene harvested from sharks, could result in a disaster, with some species becoming endangered or even going extinct.
“Harvesting something from a wild animal is never going to be sustainable, especially if it’s a top predator that doesn’t reproduce in huge numbers”, said Stefanie Brendl, founder and executive director of Shark Allies.
The conservationist group says that squalene could also be produced from plants, but that process is approximately 30 percent more expensive than harvesting squalene from sharks.
The group notes that it is in no way asking pharmaceutical companies to slow down the process of producing a COVID-19 vaccine, but merely asks them to use non-animal derived squalene.
