The studied population contracted COVID-19, the disease caused by the CCP (Chinese Communist Party) virus, between Feb. 28, 2020, and April 28, 2021.
Reinfections were counted if a person tested positive at least 90 days after their first infection. After excluding approximately 87,500 people with a vaccination record, researchers found those with immunity from having recovered from COVID-19 had little risk of reinfection and severe cases of the disease. Just 1,304 reinfections were identified. That means 0.4 percent of people with natural immunity and without a vaccination record got COVID-19 a second time.
