Is it safe to take the second gardasil shot later than recommended?

Yes. The normal schedule is to get the first dose and then the 2nd 2 months later followed by the 3rd dose 4 months after that. Many patients miss a dose. If you miss a dose you just start where you left off. You do not need to start over. As long as you did not catch hpv during the time lapse the vaccine will still be equally as effective.
