If you really want to get down in the weeds about how the FDA controls information and makes sure its advisory committees vote the way it wants them to, this is must reading. It is very long and very detailed, discussing some aspects of how FDA hid information about the Pfizer-BioNTech vaccine from its advisers, the media and the public.
I was happy that the author confirmed that the committee members who asked too many questions were not invited back by FDA for the next two Covid vaccine sessions. I especially recall that the single consumer member got canned. I watched all three meetings, and it seemed that FDA packed the advisory committee with almost half temporary members, many of whom were government employees.

SUMMARY
The global spread of SARS-CoV-2/COVID-19 is devastating health systems and economies worldwide. Recombinant or vaccine-induced neutralizing antibodies are used to combat the COVID-19 pandemic. However, recently emerged SARS-CoV-2 variants B.1.1.7 (UK), B.1.351 (South Africa) and B.1.1.248 (Brazil) harbor mutations in the viral spike (S) protein that may alter virus-host cell interactions and confer resistance to inhibitors and antibodies. Here, using pseudoparticles, we show that entry of UK, South Africa and Brazil variant into human cells is susceptible to blockade by entry inhibitors. In contrast, entry of the South Africa and Brazil variant was partially (Casirivimab) or fully (Bamlanivimab) resistant to antibodies used for COVID-19 treatment and was less efficiently inhibited by serum/plasma from convalescent or BNT162b2 vaccinated individuals. These results suggest that SARS-CoV-2 may escape antibody responses, which has important implications for efforts to contain the pandemic.
