Fever, headaches, bleed both internally and externally, sometimes organs failures.
Choosing Ebola symptoms for a false promise to be safe for a disease that has only flu-like symptoms (and has raised the average age of death).
Most of them end up in the hospital for covid anyway,

And can this can already fail to work, because the marker-antibodies and destroy-antibodies need to be in balance.
For lung infections, the T-cell immunity is much more important.
It can even give resistance, if you never had the disease.
With the experimental mRNA you can damage some of that T-cell resistance.
And that is why today most of the people in the hospitals for Covid had all their vaccine injections.
It has nothing to do with variants, but with a bad "vaccine".

If you want to be protected or cured, use Ivermectin or Hydroxychloroquine.
