Vaccines work by introducing pathogens into your body.

mRNA vaccines cause your own genome to produce these unwanted pathogens.

These pathogens are the spike protean that are in fact prions.

Your own immune system attacks the organs of your body, that adopted these spike proteins, including your brain, destroying their functionality, and your ability to think.

Seems rather straight forward to me. The shots and booster shots are working 'as designed', under the protocol of germ theory.
