Antibodies are produced after a single case of novel coronavirus pneumonia has been cured. According to the latest research, after recovering from novel coronavirus pneumonia, the patient’s body contains a large number of comprehensive antibodies that protect the body’s functions and also fight against the new coronavirus. However, the duration of antibody production varies from person to person depending on their own health, so patients who have recovered from novel coronavirus infection will not be re-infected in the near future, but they still need to pay attention to strengthening personal and daily life protection, such as reducing parties, unnecessary travel, wearing masks, and washing hands regularly.
