People's immune system has the function of memory. When infected by some viruses, cured people usually don't get sick again. Smallpox, a deadly infectious disease that has been eliminated, is one of them, and patients with this disease can get lifelong immunity after recovery. Some people think that people who have suffered from COVID-19 will not suffer from this disease again, so they don't need to be vaccinated. That was not the case.

On March 29th, official website City, the National Health and Family Planning Commission issued "Technical Guidelines for Vaccination in COVID-19 (First Edition)" (hereinafter referred to as "Guidelines for Vaccination"). According to vaccination guidelines, existing research data show that reinfection within 6 months after infection is rare in COVID-19.

Lin Zeng, chief physician of the Department of Infectious Diseases of the Third Affiliated Hospital of Sun Yat-sen University, said in an interview with the media that the key to judging whether a patient will be reinfected after being cured is whether he has enough targeted immune function.

When people are infected with COVID-19 virus, they will produce antibodies. This antibody does protect human body to a certain extent, but how strong and how long it lasts needs further observation and research. If there are no effective antibodies in the body, patients with COVID-19's disease may be reinfected.

According to previous reports, there are secondary cases of COVID-19 infection in the United States, the Netherlands, Belgium and Ecuador. COVID-19 patients are at risk of secondary infection, so it is necessary to get COVID-19 vaccine. According to the vaccination guidelines, COVID-19 virus-infected people (patients or asymptomatic infected people) can be vaccinated 1 dose after 6 months on the basis of full notification.
