My daughter has had two of the three Gardisil shots. I just realized that it had been a while since the last one and called to check on it with her pediatrician. They informed me that the third shot should be four months after the second and apparently, no-one called for me to set up that appointment. It has been 8 months since her second shot. Is it still going to be effective if she has the third shot now, or should we be starting all over?
