The Omi Kiron strain has been detected in many places around the world, and the new crown vaccine research work for the Omi Kiron mutant strain is also urgently put on the agenda
.
On December 15, a reporter from the Beijing Daily client learned from SINOVAC that, recently, SINOVAC had obtained two Omicron strains of the new crown virus from Hong Kong
"The latest laboratory research results show that one of the Omi Kiron virus strains was used to neutralize 20 doses of vaccinated with 2 doses of CoronaVac and 48 doses of vaccinated with 3 doses of CoronaVac.
In antibody testing, the positive rate of serum neutralizing antibody after 20 doses of two doses of vaccine was 35%, and the positive rate of serum neutralizing antibody after 48 doses of three doses of vaccine was 94%
.
” The relevant person in charge of Kexing said, the above The results show that the third dose of vaccine can effectively improve the neutralization ability of the serum against the Omicron virus strain
Kexing said that at present, a comparative test using another Omi Keron virus strain is underway, and Kexing is conducting further research on more sera with different antibody levels after immunization.
A comprehensive evaluation of the impact of the Rong virus strain on the vaccine
