By January 26, 2021, it was already being talked about by public health experts, that the newly rolled-out COVID-19 vaccines will likely NOT prevent infection but more importantly they don’t know if it will stop community transmission of the SARS-CoV-2 virus, the exact justification for mandating vaccines!
The vaccine trials were only designed to assess clinical disease (COVID-19) not prevention of infection or assessing their ability to stop transmission.
The argument supporting vaccination becomes that the vaccine will reduce viral load, and thus assumed to reduce community transmission. But “asymptomatic” individuals already have reduced viral load, if anything viable virus at all, and the already infected produce natural, long-lasting protection.
