A new research has found that COVID-19 vaccination offers long-lasting protection from the worst outcomes of COVID-19.
Chapel Hill [US]: A new research has found that COVID-19 vaccination offers long-lasting protection from the worst outcomes of COVID-19.
The research has been published in the 'New England Journal of Medicine'.
The emergence of the delta and omicron variants had raised questions about whether breakthrough infections are caused by waning immunity or by the more transmissible variants.

The study, which is a collaboration between the UNC-Chapel Hill and the North Carolina Department of Health and Human Services, examined data on COVID-19 vaccination history and health outcomes for 10.6 million North Carolina residents between December 2020 and September 2021.
