Waffa El Sadr, MD, MPH, MA comments in DW AKADEMIE and explains how vaccines may be ineffective in creating an immune response after changes in COVID-19 variants.

The tip of the spike protein is also altered in the New York variant. Understandably, this has caused some worry, the epidemiologist Wafaa El-Sadr of Columbia University told the German public broadcaster, ARD. “These changes can result in the spike protein being able to attach itself better. Or that the virus can reproduce more quickly. Or that it cannot be fought by the antibodies through our vaccines,” she said.
