Immune system support is particularly important if you have ever had HPV problems such as cervical dysplasia or genital warts because these problems may be an indication of a weak immune system.
Preventative maintenance is particularly worthwhile in the event you are exposed to one of the other 70+ HPV types. There is very little cross-immunity between the different HPV types. This means that if you have immunity to one HPV type, you may not necessarily have immunity to another HPV type.
