Experts based in California group of shark protectors said that 500 thousand sharks can be killed to produce vaccines against coronavirus COVID-19, the newspaper Telegraph wrote.
It is reported that one part of some potential vaccines against COVID-19 is squalene, which is produced in the liver of sharks. British pharmaceutical company GlaxoSmithKline is currently using squalene from shark liver to create adjuvants for use in flu vaccines. In May, the company said it would produce a billion doses of this compound for potential use in coronavirus vaccines.
The Shark Allies Shark Advocacy Group estimates that about 250,000 sharks would need to be killed to vaccinate all people in the world with a single dose of COVID-19, a dose containing squalene, a number that would double if each person needed two vaccines.
However, a GlaxoSmithKline spokesman said the company is “committed to protecting the environment and exploring alternative sources of raw materials wherever possible.
Earlier in July, the British authorities signed an agreement with two pharmaceutical companies – French Sanofi and British GlaxoSmithKline (GSK) – for the supply of up to 60 million doses of COVID-19 vaccine developed by the companies. By the end of this year, the companies hope to begin the third phase of the coronavirus vaccine clinical trials.
In April this year, Sanofi and GlaxoSmithKline (GSK) announced that they would join forces to develop the coronavirus vaccine. Sanofi was expected to offer its COVID-19 antigen based on the S-100 protein, based on recombinant DNA technology. As an initial contribution, GSK provided adjuvant technology (a set of substances to enhance the immune response when administered at the same time as the immunogen) that was well proven in previous pandemics. It was noted that the combination of protein antigen and adjuvant is a widely accepted method used in many active vaccines.
