You were told wrong. Shots have a ramp-up period and then a five year maintenance period where you get one shot a month. Afterwards, you've effectively been cured.
A friend just started the shots and there was no ramp up, he's getting the shots every four to six weeks from the start. When I looked into it ten years ago, you had to come in weekly for a long time, which discouraged me from doing it.
