HPV VACCINE

Currently two vaccines are available.

The first GARDASIL, prevents against HPV viruses (subtypes16 and 18) responsible for 50% and 20% of Cervical Cancer  respectively, as clinical trials made refer, and genital warts produced by this types of HPV (16 and 18). It also protects against HPV viruses (subtypes 6 and 11) responsible for 90% of genital warts that are not related to cancer. Supposed protection against HPV 16, 18, 6 and 11 in others organs.

The second CERVARIX, vaccine prevents against HPV viruses 16 and 18 and is credited with cross protection against HPV 45, thus prevent against Cervical Cancer by 75% (70% of cervical cancers attributed to HPV 16 and 18 and the remaining 5% to HPV-45).

The best age to apply the vaccine is before sexual initiation, because protection is guarantied for 6 to 8 years.  For example a teenager who applies the vaccine at age 14 is protected until the 20 to 22 years. The need for a booster after 6 years is on study.

A woman who already has relations should exclude the presence of HPV before the vaccination.  In this way we can evaluate the real effectiveness.   Here we must clarify that there are many cases where patients refers a history of normal gynecologic controls and have a viral infection not detected. The decision to apply the vaccine to women who have initiated sexual activity should be well founded.  To rule out the presence or absence of HPV is necessary a DNA study called Polymerase Chain Reaction (PCR).

There are other HPV viral subtypes that are associated with cervical cancer and others and not prevented by the vaccines, therefore people who already have been vaccinated must continue with gynecological checks.

• If a person is infected with any of the HPV virus that protects against the vaccine, it will not be effective against it.
• If a person is infected with any type of HPV should avoid vaccination.
