Abstract: Since the emergence of the new Omicron B.1.1.529 variant of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in November 2021, the number of positive cases has continued to increase. Due to its rapid spread, this new variant has become dominant worldwide. This is also the case in Morocco, where 95% of SARS-CoV-2 infections are secondary to this variant. In addition, the high number of mutations in the viral S protein has raised concerns about the possibility of escape of the virus from antibodies induced by previous infection or by vaccination. However, very few studies have reported the notion of reinfection with this new variant. We report four cases of Covid-19 reinfection with the Omicron variant, diagnosed at the Ibn Rochd University Hospital in Casablanca, in four vaccinated healthcare professionals.
