It was my understanding that natural immunity to covid19 isn’t long-lasting but does work well as a replacement for one of the two doses.

I’d love to read up on the other side though, if you happen to have any articles to share.

- The immune systems of more than 95% of people who recovered from COVID-19 had durable memories of the virus up to eight months after infection.

- The results provide hope that people receiving SARS-CoV-2 vaccines will develop similar lasting immune memories after vaccination.
