Vaccines provide protection, but never immunity. Protection always means a reduced risk of getting a disease as well as a reduction of severety, but still no perfect immunity.
In some cases this protection stays in place for a long term, but a refresher is still needed every now and then, unless there are external reasons (like living in a very-low-risk area).

According to the definition of immunity provided by our U.S. Center for Disease Control and Merriam-Webster dictionary they most certainly do provide an immunity.
