Review the breakthrough infections carefully.
By following participants who received a fourth-dose vaccination with Ad5-nCoV or the inactivated SARS-CoV-2 vaccine, we observed that 78.01% (149/191) of participants were infected or suspected to be infected with SARS-CoV-2
127/191 of the participants developed symptoms and had positive nucleic acid or antigen test results
The above-mentioned sounds outrageous.
Within this study description, they mention…
The overall infection rate during the nationwide COVID-19 pandemic that followed the Chinese government’s “New ten measures” policy issued on 7 December 2022 (21) was estimated at 87.54%.
Can this 87.54% overall infection rate be used to draw conclusions about the efficacy of this vaccine in terms of a decrease in the transmissibility of infection?
I guess it depends on how they derived that value.
Doesn't this crap seem outrageous?…..
