No, vaccinations prevent you from getting sick. It’s the choice between a mild illness and potentially being admitted into the hospital.

What we’re starting to see is potential for further variants to evade antibodies, reproduce inside you and thus you spread it. Your immune system is still able to fight the virus easier because the vaccine has trained your immune system to look out for contagions like this virus but for a while you’re still actively spreading the virus before you’ve cleared it from your system.

Someone correct me if I’m wrong though.
