It decreases the viral load that can be passed on. Someone gets vaccine. Vaccine causes production of antibodies. Antibodies kill virus. Now someone cough on my grandpa and he gets hit with less live virus than if the cougher wasn't vaccinated. My grandfather has been vaccinated but because he works with lots of people and doesn't wear his mask like he should he got COVID and then pneumonia and was hospitalized. Imagine if he wasn't vaccinated and got that heavy of a viral load? He'd be dead. This is all basic stuff you should have learned in middle school science.
