CDC: “Before Delta became the predominant variant in June, case rates were higher among persons who survived a previous infection than persons who were vaccinated alone. By early October, persons who survived a previous infection had lower case rates than persons who were vaccinated alone.”
Surviving a previous Covid infection provided better protection than vaccination against Covid-19 during the Delta wave, US federal health authorities said, citing research showing that both the shots and recovery from the virus provided significant defense.
