MONDAY, Sept. 27, 2021 (HealthDay News) — COVID-19 vaccines are highly effective under real-world conditions in preventing symptomatic disease in health care personnel, according to a study published online Sept. 22 in the New England Journal of Medicine<\/em>.<\/p>\n Tamara Pilishvili, Ph.D., from the U.S. Centers for Disease Control and Prevention in Atlanta, and colleagues assessed the effectiveness of COVID-19 vaccines in a real-world setting using data from 1,482 case participants and 3,449 controls. <\/p>\n The researchers found that for partial vaccination, vaccine effectiveness was 77.6 percent for Pfizer-BioNTech (BNT162b2) and 88.9 percent for Moderna (mRNA-1273), whereas for complete vaccination, vaccine effectiveness was 88.8 and 96.3 percent, respectively. Effectiveness was similar regardless of age (<50 years or \u00e2\u0089\u00a550 years), race and ethnic group, presence of underlying conditions, and level of patient contact.<\/p>\n “In this population of health care personnel, vaccine effectiveness was similar among persons with underlying medical conditions or other risk factors for severe COVID-19, including pregnancy; in different subgroups of health care personnel defined according to job category; and in racial and ethnic groups that have been disproportionately affected by the pandemic,” the authors write.<\/p>\n
