About COVID-19
COVID-19 is an acute respiratory infectious disease. People are generally susceptible. Currently, the patients infected by the novel coronavirus are the main source of infection; asymptomatic infected people can also be an infectious source. Based on the current epidemiological investigation, the incubation period is 1 to 14 days, mostly 3 to 7 days. The main manifestations include fever, fatigue and dry cough. Nasal congestion, runny nose, sore throat, myalgia and diarrhea are found in a few cases.
The vaccine of COVID-19 generally needs two injections, and usually produces protective neutralizing antibodies about 7 days after the second injection. However, due to the difference of individual immunity, not everyone who has been vaccinated will produce neutralizing antibodies.
Some people who have been infected with the COVID-19 also produce protective neutralizing antibodies.
There are no definite evidence whether neutralizing antibodies can protect the mutated COVID-19. There are still lack of sufficient research on the protection period of neutralizing antibody.
