Woman, 31, catches Covid twice within three weeks in Spain

Scientists report shortest known gap between infections in fully vaccinated healthcare worker

A 31-year-old woman in Spain caught Covid twice within 20 days, the shortest known gap between infections, scientists have reported.

Researchers in Spain gave details of the healthcare worker, who tested positive a few days before Christmas in December 2021 and again in January 2022. The case is further evidence that the Omicron variant can evade immunity from even recent previous infections.
