My research with long Covid and the vaccine leads me to think there is much even the physicians do not understand at this time. The spike protein in the vaccine has been found up to months in a person's body. It was "assumed" (and I use that phrase as ideas seem to be changing every month or so) that the tiny amount of viral material would be limited to the respiratory system and then expelled naturally within a few weeks.
They have now found this protein in the GUT and remaining there for months. Obviously this means it can travel throughout the system and create symptoms wherever there is a vulnerable receptor site. My studies include a wealth of information from the UK which seems to be more forthcoming than the US.

There is too much information to place in a comments section, but perhaps someone will want to respond to my comments and could possibly a group could be formed to discuss this further.
I have had Covid 3 times and had the first two vaccines. I refused to have further since the variants appeared as stats showed that the vaccine lasts less and less time than the original. Also the body's own immune system seems to provide extended protection.
I would appreciate any comments, as this is the first time I am printing this. I am a RN with an advanced degree and extremely concerned about this country's response to Covid.
Thank you if you read this. Faith L.
