It's not a vaccine by definition because it doesn't prevent a person from getting the disease. In fact you might even have an increased risk. As of now there really isn't any good evidence that it is net positive for anyone. You might have a small amount of resistance to the disease that is short lived but then studies have shown that without continued boosters it can drop below the level you were at to begin with. Couple that with the risk of side effects which are real and not nearly as rare like they want you to believe. These risks compound with each shot you have. Also, there are other treatments that work very well. Doctors that were brave enough to implement these treatments had 80-90% success. Much better than the so called vaccine.
