Researchers say in a newly released study that prior infection with COVID-19 offers long-lasting and comprehensive immunity against severe and fatal cases of the virus.
The study, published online at medRxiv and not yet subject to peer review, was conducted by a team of researchers largely based out of Qatar. The scientists in the preprint stated “the future of the SARS-CoV-2 pandemic hinges on virus evolution and duration of immune protection of natural infection against reinfection.”
They also said that while immunity derived from “natural infection” offers a relatively quickly-waning protection against re-infection, the durability of natural immunity against severe reinfections was robust and long-lasting. Source: Just the News
