Risk of COVID very low in vaccinated medical workers: study

COVID-19 infection was very low in a cohort of vaccinated California healthcare workers (HCWs) amid a surge of new cases, according to a research letter yesterday in the New England Journal of Medicine. 'We were able to describe the infection rates in a real-world scenario, where vaccine roll-out coincided with a surge of infections,' coauthor Jocelyn Keehner, MD, of the University of California San Diego (UCSD), said in a UCSD news release. 'We observed a low overall positivity rate among fully immunized health care workers, supporting the high protection rates of these vaccines.'
