According to wildlife experts, half a million sharks could be killed in an attempt to produce the Covid vaccine



About half a million sharks could be slaughtered in an attempt to make a Covid-19 vaccine, wildlife experts said.

The best predators are harvested for squalene, a natural oil produced in the liver of sharks, which is used as a medicine, even in current flu shots.

The ingredient is used as an adjunct to increase the effectiveness of a vaccine by creating a stronger immune response.

It is used in some of the candidates for a Covid-19 vaccine.

If any of these vaccines are used around the world, the Shark Allies conservation group believes around 250,000 sharks will need to be slaughtered to provide a dose for each person.

However, some scientists believe two doses may be needed to immunize the population, meaning around 500,000 sharks would need to be slaughtered, according to the California-based group̵

Stefanie Brendl, founder and executive director of Shark Allies, said: “ Collecting something from a wild animal will never be sustainable, especially if it is an exceptional predator that does not breed in large quantities.

There are so many unknowns about how big and how long this pandemic could last, and then how many versions of it we have to go through, that if we continue to use sharks, the number of sharks taken for this product could be really high, year after year. after year.

In a post on Facebook, he added: ‘We are not trying to slow down or hinder the production of a vaccine.

“We are simply asking that tests on non-animal derived squalene be conducted alongside shark squalene so that it can be replaced as soon as possible.

“At the billions of doses needed per year, for decades to come, it is imperative not to rely on a wild animal resource. It can be harmful to shark species that are hunted for their oil and is not a reliable supply chain. “.

The group has launched an online petition called “Stop Using Sharks in COVID-19 Vaccine – Use EXISTING Sustainable Options”.

In the Change.or petition, which attracted nearly 9,500 signatures out of 10,000 targets, the group says there are “better alternatives” to using squalene in vaccines.

The group says shark liver oil-based squalene is used more commonly because it is “cheap to obtain” and “easy to find.”

But they say the chemical structure of the squalene compound is identical in sharks and non-animal alternatives, meaning its efficacy in vaccines should be identical regardless of its source.

All plants and animals produce squalene as a biochemical intermediate and it can be produced from non-animal sources including yeast, sugar cane and olive oil.

What is squalene and why is it used medicinally?

Squalene is a natural oil produced in shark liver, which is used as a medicine, even in current flu shots.

The name derives from “Squalas”, a genus of catfish shark.

The ingredient is used as an adjunct to increase the effectiveness of a vaccine by creating a stronger immune response.

It is used in some of the candidates for a Covid-19 vaccine.

According to environmentalists’ estimates, around three million sharks are killed each year for squalene, which is also used in cosmetics and machine oil.

However, all plants and animals produce squalene as a biochemical intermediate, including humans.

Conservationists have called on companies to use synthetic alternatives in the Covid-19 vaccine.

Shark Allies says a company, Amyris, one of the squalene producers, based in California’s Silicon Valley, uses a process that derives squalene from sugar cane.

In their most recent statement, the company claims it can produce squalene for a billion vaccines in a month or less.

The company’s synthetic squalene is not yet approved for use in vaccines.

However, its chief executive, John Melo, said he is in talks with regulators in the United States to allow its use as an alternative adjuvant in vaccines currently formulated to use shark-based squalene.

According to the World Health Organization (WHO), there are 40 candidate vaccines for Covid-19 in the clinical evaluation and 142 vaccines in the preclinical evaluation.

Shark Allies states that, of these vaccines, 17 use adjuvants and five of these adjuvants are squalene based.

The group also expressed concern about the areas where sharks are slaughtered and said they often come from countries that are “poorly regulated in terms of fishing and fish oil production.”

Squalene often comes from small private fishing operations in the Pacific Ocean from countries such as Indonesia and the Philippines and is processed in China.

They warn that increased demand could increase pressure on shark populations in those countries, as well as in Europe and the United States, while raising concerns about the already vulnerable gulper shark, which is rich in squalene.

According to environmentalists’ estimates, around three million sharks are killed each year for squalene, which is also used in cosmetics and machine oil.

About 3,000 sharks are needed to extract one ton of squalene.
