Two new studies suggest COVID-19 immunity following infection could last a year, or "possibly a lifetime, improving over time especially following vaccination" The New York Times reported on Wednesday, hopefully allaying "lingering fears that protection against the virus will be short-lived."

When taken together, the studies suggest most (but not all) vaccinated individuals who were previously infected with COVID-19 "will not need boosters," wrote the Times. Those who were vaccinated without having previously contracted the virus will likely need the extra dose. Experts expect immunity in these individuals to "play out very differently," as "immune memory" may look different following vaccination compared to natural infection.
