I find it hard to believe they “didn’t want the public to know” when one of the earliest studies the CDC did on vaccines, with a March 2021 publish date, was a study that tested weekly regardless of symptoms to see if it prevented infection outright. Maybe not perfect sterilizing immunity but it does prevent asymptomatic.
I agree they didn’t get into the nuances of sterilizing vs. non sterilizing but for the general public that’s deep in the weeds, anyone who followed the details knew this was the case early on.
> “One of this study’s strengths is its design: participants self-collected nasal swabs each week for RT-PCR laboratory testing, regardless of whether they had developed symptoms of illness. Researchers were able to look for evidence of SARS-CoV-2 infection irrespective of symptoms. A small number (10.7 percent) of infections in this study were asymptomatic (i.e., did not result in symptoms). However, the majority of infections (58 percent) occurred among people whose infections were identified by testing before they developed symptoms or knew they were infected. The study demonstrates that these two mRNA vaccines can reduce the risk of all SARS-CoV-2 infections, not just symptomatic infections.
This is important because preventing both asymptomatic and pre-symptomatic infections among health care workers and other essential workers through vaccination can help prevent the spread of SARS-CoV-2 to those they care for or serve. Findings from this study complement earlier reports that these two mRNA COVID-19 vaccines can reduce both asymptomatic and symptomatic SARS-CoV-2 infections.“
