According to the data of papers published by the research team, the inactivated covid-19 vaccine is not only safe, but also has obtained high titer of sars-cov-2 specific IgG antibody. After six weeks of vaccination, the neutralization titer of serum is as high as EC50 10e4, which is significantly higher than the plasma of the rehabilitation patients reported in the previous literature.
