We’re not all equal in the face of the coronavirus

HLA genes, responsible for the adaptive immune system, differ between individuals. Thousands of possible variants have been identified. Not all of them are equally effective in fighting new viruses. The frequency of these variants varies from one population to another. In a study to be published in the journal HLA, scientists have pinpointed those that are potentially the most effective against the SARS-CoV-2 coronavirus. They have also brought to light significant differences between populations.
