Zhang Wenhong: The toxicity of Omike rong cannot be ignored
The import risk in the next six months is very high
Recently, the domestic epidemic situation has been sporadic at many points, and according to the published circulation situation, some of them have come from relatively independent overseas imports. Zhang Wenhong said, "In the next six months, the import risk should still be very high. ”
In Zhang Wenhong's view, the severe illness of Omi Kerong is declining, but the toxicity cannot be ignored. His team made a wide-ranging comparison of the Ami keron and Delta viruses, the former causing no less fever than the latter.
"Judging from the latest calculated case fatality rate in the United States, if nothing is really done, it will have very serious consequences." Speaking about China's experience in fighting the epidemic, Zhang Wenhong said with confidence: "If we are fast enough and the epidemic prevention runs ahead of the virus, we can win every victory of dynamic zero clearance." ”
Zhang Wenhong: The COVID-19 vaccine has been effective in reducing severe illness and mortality

Zhang Wenhong said that studies on mutants have confirmed that the new crown vaccine has a significant effect on reducing severe illness and mortality, especially the third dose of vaccine can increase antibody levels by dozens of times.
As for the fourth stitch, Zhang Wenhong believes that it is too early to say, "There is no need to be so anxious now, and we can have more international experience for us to use." ”
