LISBON, Portugal — A fully vaccinated and boosted health care worker tested positive for the omicron variant of SARS-CoV-2 just 20 days after testing positive for the delta variant, researchers reported here.
The case demonstrates omicron’s ability to evade previous immunity, they said.
Gemma Recio, MD, of the Institut Català de Salut in Tarragona, Spain, and colleagues presented the case at the European Congress of Clinical Microbiology and Infectious Diseases.
The conference said in a press release publicizing the report that it was the shortest known gap between SARS-CoV-2
