At the beginning of the 18th century, the British rural doctor Edward Jenner inoculated a child with smallpox pathogens obtained from the purulent wound of an infected with smallpox, the fact is that the boy survived and was immunized against smallpox.

Jenner actually inoculated James Phipps (the child) with fluid from a cowpox blister, not from a smallpox blister. Source for this claim.

After this event and to this day, all vaccines work in the same way, inoculating a "stunned" version of the virus so that the patient's immune system is trained and can recognize it

This is false. Some vaccines work by introducing attenuated viral particles into the system of an individual, but not all vaccines function this way. Some vaccines use an inactivated pathogen, these so called vaccines are called inactivated vaccine. In this case the virus isn't stunned but the mechanisms for transmission and virality are destroyed (such as the destruction of the genetic material). Another type of vaccine is a sub-unit or recombinant vaccine which includes the pfizer vaccine. Recombinant vaccines work by taking a piece of the virus (either genetic material, capsid, certain spike proteins, etc) and using those pieces to trigger the immune response. The pfizer vaccine uses the RNA sequence for the spike protein which your cellular machinery will construct and then build an immune response against.Source 1 for this claim. Source 2 for this claim.

All viruses, including COVID, are made up of a piece of RNA wrapped in a layer of fat and with spicules that they use as keys to enter the host cell.

I mean this is incorrect as there are viruses that use DNA such as adenoviruses, herpesviruses, and poxviruses. Source for this claim.
