COVID-19 Vaccine Reduces Severity, Length, Viral Load for Those Who Still Get Infected

Real-world data from the AZ HEROES study show COVID-19 vaccines are highly effective in preventing SARS-CoV-2 infections, and when breakthrough infections do occur, the level of infection and impact of the disease are significantly reduced. Dr. Jeff Burgess, associate dean for research, professor at the Mel and Enid Zuckerman College of Public Health, and PI on the study says that in addition to continuing research into COVID-19 immunity and vaccine efficacy, AZ HEROES researchers are beginning to examine the frequency of SARS-CoV-2 variants.
