What we know: Different types of COVID-19 immunity

As health leaders discuss how vaccination and the recent large numbers of COVID-19 infections might be coming together to usher the current pandemic into an endemic phase, there is more insight forming about how the different types of COVID-19 immunity might factor into that move.

A new report from the Centers for Disease Control and Prevention suggests that, separately, COVID-19 immunity from prior infection and from vaccination are both better than no immunity at all. However, the two sources of immunity together might provide the best level of protection.

The report looked at coronavirus cases and hospitalizations in California and New York from May to November 2021, covering the period of time when the delta variant became the predominant strain in those states.

The report states that, before and during the delta surge, people without vaccination and without infection immunity had the highest case and hospitalization rates. After delta gained its predominance, vaccinated people without prior infections and unvaccinated people with prior infections had lower rates, and vaccinated people with prior infections had the lowest rates of all groups.
