Nothing ground breaking IMO. I think most people assumed natural immunity lasted longer than it was given credit for and obviously all studies have limitations but this was the result:
"Anti-RBD levels were observed after a positive COVID-19 test result up to 20 months, extending previous 6-month durability data.5"
