Very few vaccinated. These people were discharged from hospital in Madrid before 16 May 2020, so the last patient will have been infected only about three months after the high-volume vaccination campaign started. If you assume that analysis and writing the paper took a month or two, then the last patient was infected maybe a month after vaccination started. But considering how much the chance of hospitalisation is reduced, that'll probably still be the same today.
