People have been looking at the Zelenko Protocol. I think he called it the Zstack.
I know that people try ivermectin. I wonder if bentonite clay will do anything to remove impurities. Another thing I have heard of is chlorine dioxide. There are websites and videos about how to use it. You can purchase the ingredients on Amazon, for what its worth.
I am not sure how long ago he got it, but I do recall that people were using blood cupping therapy right after the injection. Maybe talk to someone who provides that service and see what they recommend.
I did not see him clutch his chest. Where is the video of that? I saw him sit back and go down. His arms moved because of his momentum when he hit the ground.
