Coffey County, Kansas, Nurses Refuse to Give COVID-19 Vaccines
Kansas is in the middle of a coronavirus emergency, but some health-care workers are spreading misinformation instead of healing.www.thedailybeast.com

The Pfizer medical director was on a Dutch talk show tonight and he explained that the vaccine attacks the whole spike protein, not only a part of it. So there is a good chance their vaccine will work on the mutations as well, at least partly.We've got a new mutation of SARS-CoV2, this time the changed part is the crucial spike protein. This renders antibodies generated by vaccination completely useless. In case you already had the disease it means you can be infected by this new strain of the virus.
Here we show that this lineage exhibits complete escape from three classes of therapeutically relevant monoclonal antibodies. Furthermore 501Y.V2 shows substantial or complete escape from neutralizing antibodies in COVID-19 convalescent plasma.
Question is now if other scientists are going to confirm this study and its results, or not.

SARS-CoV-2 501Y.V2 escapes neutralization by South African COVID-19 donor plasma
SARS-CoV-2 501Y.V2, a novel lineage of the coronavirus causing COVID-19, contains multiple mutations within two immunodominant domains of the spike protein. Here we show that this lineage exhibits complete escape from three classes of therapeutically relevant monoclonal antibodies. Furthermore...www.biorxiv.org
Do we know anymore about it, like how infectious it is, and how likely you are to be develop symptoms and how serious they're likely to be?We've got a new mutation of SARS-CoV2, this time the changed part is the crucial spike protein.

Apparently we are living in a future where drugs get software updates.He also told that it is possible for Pfizer to reprogram the vaccine within 6 weeks if needed.
But it would take a lot longer to get it approved again.

Well according to this study he is wrong. They used blood plasma, which contained antibodies created as response to the other strains, and those didn't do anything to the virus at all.The Pfizer medical director was on a Dutch talk show tonight and he explained that the vaccine attacks the whole spike protein, not only a part of it.

As I understand it, though, both the Pfizer and Oxford/AstraZeneca work vaccines by targeting the characteristic protein spikes on the outside of the virus , which are harmless in themselves, but which the virus uses to hook onto and attack the body's cells.Well according to this study he is wrong.

I mean it makes sense. My limited understanding is this: proteins are really complicated, three dimensional structures. In order for an antibody to react with it it needs to fit it like a glove. If the protein changes, then it is like trying to fit a square into a circle, only on a much higher complicated level - impossible to do. No match.
Again question is still if the results of this study will be confirmed by others or not.
Same; and I'm just going to trust that the companies making the vaccine understand their vaccines better than I do as just a curious layperson.As I understand it, though, both the Pfizer and Oxford/AstraZeneca work vaccines by targeting the characteristic protein spikes on the outside of the virus , which are harmless in themselves, but which the virus uses to hook onto and attack the body's cells.
The vaccination starts producing the spikes (and only the spikes) inside the patient's body, and the body's immune system learns to recognise and destroy them.
So if in future the body's immune system recognises those spikes, it knows to attack them and anything of which they're part -- that is, the antibody is reacting to the spike, not to the more complex geometrical object of which the spike is only a component part.
So if the new strain's spikes are sufficiently similar to those of older variants, there's a good chance the Pfizer and Oxford vaccines will be effective against the new strain too, however it may differ from earlier strains in other ways.
That's my understanding, anyway.
