Ugur Sahin, a German-Turkish oncologist and immunologist and the CEO of the German biotechnology company BioNTech, told Spiegel that people will have to get a fourth dose in summer if Omicron stays the most prevalent variant until then.
Sahin said new highly-mutated variants of the coronavirus could “certainly” emerge.
He said studies show that people who have received three doses of anti-Covid vaccine, are significantly immunized against Omicron.
The new variant, Omicron, was an unexpected one, Sahin said, explaining that he did not anticipate such a mutation until another year.
The coronavirus first emerged in China’s Wuhan in November 2019, and, after it quickly spread to elsewhere in the world, a pandemic was declared on March 11, 2020. So far, at least 5,944,043 people have died of the disease caused by the virus around the world.
