First of all, hope you feel better soon.. From what I hear vitamins C,D and Zinc all help. A supplement called NAC is also supposed to help prevent clots, which are the primary danger.
This kind of thing just shows that these shots are NOT a 'vaccine'... never have been, never will be. They are no different than a yearly flu shot in effect.
My thoughts also, I believe after a few years have passed we will see an entirety new treatment plan, that is if we get control of the potus and congress.
To the op I wish you well, and praying for you.
