This site provides links and brief descriptions of robust scientific/medical studies of natural immunity after recovery from a Covid-19 infection, which is more reliable than immunity after a positive Covid test result.
- The Immune Response page covers studies of the layers of protection the immune system develops in response to an infection.
- Pre-'21 Uptick covers measured effectiveness of the immunity prior to Summer 2021.
- '21 Uptick covers measurements of immunity during the summer 2021 worldwide uptick in new Covid infections.
- Experts Inform covers press articles and an interview in which medical experts inform the public about what's known from the data in the studies.
The articles covered are well written and relatively easy to understand, so you are encouraged to read them for further details.
The Brownstone Institute has also compiled many
further high-quality studies at
