Active vaccines aka viral vector or mRNA vaccines are the culprits. Very stupid idea to program human cells to produce a toxin protein that is in itself a clot causing little bitch and causing the T-cell balance to be tilted because of that said production.

That production tilting means the number of general, first responders aka CD8+ killer T-cells drop. That leaves the door wide open for all kinds of viruses, bacteria and cancers. Firewall literally breached.
