AbstractSARS-CoV-2 can mutate to evade immunity, with consequences for the efficacy of emerging vaccines and antibody therapeutics. Herein we demonstrate that the immunodominant SARS-CoV-2 spike (S) receptor binding motif (RBM) is the most divergent region of S, and provide epidemiological, clinical, and molecular characterization of a prevalent RBM variant, N439K. We demonstrate that N439K S protein has enhanced binding affinity to the hACE2 receptor, and that N439K virus has similar clinical outcomes and in vitro replication fitness as compared to wild-type. We observed that the N439K mutation resulted in immune escape from a panel of neutralizing monoclonal antibodies, including one in clinical trials, as well as from polyclonal sera from a sizeable fraction of persons recovered from infection. Immune evasion mutations that maintain virulence and fitness such as N439K can emerge within SARS-CoV-2 S, highlighting the need for ongoing molecular surveillance to guide development and usage of vaccines and therapeutics.
Quotes in a signature is annoying, as it comes across as an independent post.
@Kobe Bryant Turns out, COVID kills lots of people. I heard that more frum people have died of COVID in Lakewood in the last month than died of all causes in Lakewood the entire 2019 (!!).Anybody have any idea how I could further verify if those numbers are accurate or not?
Huh? Only 17 Lakewood people died in 2019? There's gotta be a qualifier that you're missing here.
You seem to be intimately familiar. Can you break it down by numbers, age, underlying conditions?
So the entire world is celebrating Pfizer's 90% efficiency of Vaccine candidate. Aren't naturally occurring antibodies more efficient than 90%, yet are being mostly ignored in policy decisions?#FollowTheMoney #BigPharma
Naturally occurring antibodies kill .65% of patients, not to mention numerous horrific side effects already documented, so I’d prefer to go with the antibodies that may or may not cause transverse myelitis in one in 40,000 cases.
The truth that you state doesn't negate the fact that antibodies that have already been shown to exist should be considered in policy decisions.

The CDC recognizes them as effective regarding quarantine requirements for 3 months, do they not?
For Anyone Who Has Been Around a Person with COVID-19Anyone who has had close contact with someone with COVID-19 should stay home for 14 days after their last exposure to that person.However, anyone who has had close contact with someone with COVID-19 and who meets the following criteria does NOT need to stay home.Has COVID-19 illness within the previous 3 months andHas recovered andRemains without COVID-19 symptoms (for example, cough, shortness of breath)
Correct
