New research from the University of North Carolina at Chapel Hill suggests that people who have had COVID-19 may need only one shot of vaccine.
The study led by the UNC School of Medicine and UNC Gillings School of Global Public Health showed one dose of either the Pfizer-BioNTech or Moderna vaccine — known as mRNA vaccines — boosted antibodies among those who previously had COVID-19.
“These results support a new and growing body of research suggesting that prior coronavirus infection may act as a primer for the immune response to the first dose of mRNA-based COVID-19 vaccine,” said first study author Emily Ciccone, a clinical instructor and fellow in the Division of Infectious Diseases at the School of Medicine.
