“Does the covid vaccination prevent you from getting the virus disease or just reduce the symptoms of the infection?”
Nope. Its “leaky” aka non-sterilizing immunity

A leaky vaccine, means that only the symptoms of the disease are prevented. Infection of the host and the transmission of the virus are not inhibited by the vaccine.
This contrasts with most other vaccines, where infection of the host is prevented.
You are tampering with the natural mutation process and potentiating deadly strains that will both evade the vaccines and kill at a much higher rate.
What I’ve been hearing is that the real danger of taking the vaccine comes later down the road when you are exposed to the wild virus again. It’s called Antibody Dependent Enhancement (ADE) and it was 100% fatal in the animal studies that were done.
