The Future is Now: Understanding the HPV Vaccine Guidelines E.J. Mayeaux, Jr., M.D. Professor of Family Medicine Professor of Obstetrics and Gynecology Louisiana State University Health Science Center Shreveport, LA
Case #1 Your 11 year old female patient presents to the office for a sports physical and health maintenance. Her mom wants to discuss HPV vaccines with you. Correct information you can give her include: 1.The available vaccine is made from live virus. 2.It is based on virus-like particles that induce neutralizing antibodies. 3.It has only been studied in a small number of people. 4.It has not been shown to decrease abnormal Pap smears.
Vaccines Against HPV Epidemiologic studies suggested HPV has type-specific immunity Type-specific neutralizing antibodies Virus-like particles (VLPs) are recombinant viral capsids that induce neutralizing antibodies L1 major capsid protein VLPs are highly immunogenic ? some cross protection within families Outcome data preliminary Schiller JT et al. Nat Rev Cancer. 2004;2:
Vaccines Against HPV VLPs have no viral DNA Can NOT cause infection Since there is no viral DNA, It can not make oncogenic proteins There is no risk of cancer with a HPV VLP vaccine
Creation of VLPs 1. Berzofsky JA et al. J Clin Invest. 2004;114:450– Kirnbauer R et al. Proc Natl Acad Sci USA. 1992;89:12180– Modis Y et al. EMBO J. 2002;21:4754–4762.

You should inform her it is indicated for: 1.The 14 year old son. 2.The 7 year old daughter. 3.The 19 year old daughter. 4.All of the above.
ACIP Recommendations Licensed by FDA – June 8, 2006 Recommendations by ACIP – June 29, 2006 Routine vaccination with 3 doses of quadrivalent HPV vaccine for females 11–12 years of age Can be started in females as young as 9 years of age Catch-up vaccination for females 13–26 years not previously vaccinated or who have not completed the full vaccine series Ideally given before potential exposure to HPV. Advisory Committee on Immunization Practices (ACIP). ACIP recommendations for the use of quadrivalent HPV vaccine. Available at: Accessed December 19, 2006.
Most Effective Time to Vaccinate Is Before Exposure In an analysis of 1552 adolescents and young adults, the subset (n=1014) featured in this chart reported having engaged in sexual intercourse.

Quadrivalent HPV 6/11/16/18 Vaccine Dosage and Administration 3 separate 0.5-mL doses: Administered at 0, 2, and 6 months Minimal intervals 1 month between dose 1 and 2 3 months between dose 2 and 3 IM injection in the deltoid or thigh No preservatives (no thimerasol) OK with Tdap, Td, and MCV4.
Case #4 Your next patient is a 22 year old female who desires immunization against HPV. Contraindications for her receiving the quadrivalent vaccine include: 1.She has an ASCUS Pap test with a positive Hybrid Capture II high-risk test. 2.She has HIV disease with a CD-4 count of She is pregnant. 4.She is lactating.
ACIP Recommendations Current recommendations for cervical cancer screening have not changed for quadrivalent HPV recipients. Females who have an equivocal or abnormal Pap test, a positive Hybrid Capture II high-risk test, or genital warts can receive the quadrivalent HPV vaccine. NO therapeutic effect on existing Pap test abnormalities, HPV infection, or genital warts. Vaccination would provide protection against infection with vaccine HPV types not already acquired. Lactating women can receive the vaccine. Immunocompromised females can receive the vaccine. Effectiveness might be < immunocompetent females. ACIP. Recommendations for the use of quadrivalent HPV vaccine. Available at: Accessed December 19, 2006.
ACIP Recommendations HPV-4 is not recommended in pregnancy. Individuals should report any exposure to the vaccine during pregnancy to the vaccine pregnancy registry. HPV-4 vaccine can be administered to females with minor acute illnesses. Vaccination of people with moderate or severe acute illnesses should be deferred until after the illness improves. ACIP. Recommendations for the use of quadrivalent HPV vaccine. Available at: Accessed December 19, 2006.
