The main observation indicators are shown in Table 2.

  • As mentioned earlier, complete vaccination with Kexing vaccine has a 65.9% protection against symptomatic COVID-19;
  • The protection against hospitalization is 87.5%;
  • ICU protection for preventive income is 90.3%;
  • The protection against death from COVID-19 is 86.3%.

However, only one dose of Kexing vaccine has very weak protection, followed by 15.5% for symptomatic COVID-19; 37.4% for prevention of hospitalization; 44.7% for prevention of income in ICU; and 44.7% for prevention of COVID-19 -19 Death protection is 45.7%.
