It says it can take days or weeks for antibodies to build up, you should have coverage from previous vaccines.
I don't think anyone knows the exact moment it starts working but it usually takes days or weeks for the cells to produce the antibodies so you're not protected exactly right away. that is why it's important to get your boosters on time.
