美 연구팀 "코로나19 걸린 사람 면역 수년간 유지될 수 있어"
A new study shows people who have contracted and recovered from COVID-19 could remain immune for years.
According to scientists at a medical institute in California,... participants who had COVID-19 eight months prior still had enough immune cells to fight off the virus.
The research studied 185 cases,... including 41 cases with people infected six or more months prior.
Only a small number of recovered patients did not have long-lasting immunity.
