Data from an Italian study investigating risk factors for reinfections demonstrated that regardless of the prevalent virus variant, being unvaccinated was the most relevant risk factor for reinfection.

A study from Qatar showed that immunization after primary infection provided an 85% reduction in breakthrough reinfection.
