Covid 19 vaccine is a quantity of chemicals design to help your body defeat or ward off covid 19 virus. It is not really a vaccine. Supposedly there is not covid virus in the injection. Hence the waver when getting injection. Some say it alters DNA. I am not sure what it is. I never had to sign a waver for other vaccine shots.
Vaccine - suspension of weakened, killed, or fragmented microorganisms or toxins or of antibodies or lymphocytes that is administered primarily to prevent disease.
This is how older vaccines work. New vaccines use RNA or DNA which is often engineered in the lab.
