After immunization with the original vaccine, the neutralizing antibody level of the vaccinated people increased rapidly and greatly. Although the antibody level decreased after 6 months of intensive immunization, the lowest value of the decrease was still higher than the peak value after two or one doses of vaccination, indicating that the protective effect of the vaccine was increasing.
