I'm curious about the cervical cancer vaccine.

Hello, I am curious about the removal in this event, which is the cervical cancer vaccine. I found out that it is similar to breast cancer and that women should pay attention to this type of cancer these days. First, I wonder if once you get the cervical cancer vaccine, you don't need to get it again for life, and I want to know how much it suppresses cancer. Also, I am curious about the age range for vaccination and the cost.
