The learner should be able to:1. Discuss latest trends in HPV disease prevalence and

prevention.

2. Employ evidence-based techniques for increasing HPVvaccination rates in your own practice.

3. Apply useful & compelling communication strategiesandpractical tips to inform parents about HPV.

Every year in the United States over 30,000 people are diagnosed with a cancer caused by HPV.

That’s 1 case every 20 minutes.

2017 Immunization Schedule

Age at 1st dose of HPVvaccine

Before 15th Bday: 2doses On or after 15th Bday: 3dosesImmunocompromised: 3 doses

What Forms of “Immunocompromise” Necessitate a 3-dose HPV Vaccine Series?

Needs 3 doses irrespective of age:Primary or secondary conditions thatmight reduce cell-mediated or humoral immunity

Examples:o B lymphocyte Ab deficiencieso T lymphocyte complete or partial defectso HIV infectionso Malignant neoplasmo Transplantationo Autoimmune diseaseo Immunosuppressive therapy

Can use 2-dose series for those initiatingbefore 15th birthday:

Asthma Asplenia Diabetes mellitus Sickle celldisease Chronic granulomatous disease Chronic disease of liver, lung, kidneys Heart disease CNS barrier defects (eg, cochlearimplant) Complement deficiency, persistent

complement component deficiency

2 –Dose Immunogenicity Trial

Does Immunity Last?

Follow-up through month 60

RESULTS:Antibody kinetics• Similar in 2 groups• Steady• > Natural infection

2 doses (0, 6 mos) (ages 9-14 y)3 doses (0, 1, 6 mos) (ages 15-25y) Natural infection

Data Source: Adopted from Romanowski, 2016

Evidence of lasting immunity

For 2-or 3-dose series? No evidence of waning protection after a 3-doseseries So far, antibody persistence after a 2-dose seriesappears

similar to 3-dose series

How long? Data available through ~10 years for 2vHPV and4vHPV Longer follow-up, through 14 years, ongoing insome

HPV Vaccine Long-Term Safety DataNo increased risk of:

2011- Allergic reactions, anaphylaxis, GBS, stroke, bloodclots, appendicitis, or seizures (than unvaccinated or who received other vaccines)

2013 –Blood clots or AEs related to the immune & CNS (almost1 million girls)

2012 & 2014 – Autoimmune disorders (2studies) 2015 – Multiple sclerosis or other demyelinating diseases 2016- Over 60conditions 2012 - Vaccine may be associated with skin infections where the

shot is given during the two weeks after vaccination and fainting on the day the shot is received

How Should We Introduce the Vaccine?

Opel et al: ‘Presumptive recommendation’“We have some shots to do today”Observational study

Brewer et al: ‘Announcements’“Your child is due for 3 vaccines today…”RCT

Putting Presumptive into Practice: Same Day, Same Way

“Your child needs 3 vaccines today- Tdap, HPV and meningococcal”

“Today, your child should have 3 vaccines. They’re designed to protect him from meningitis, cancers caused by HPV and tetanus, diphtheria, and pertussis.”

Standing OrdersSingle physician order for all patients for

recommended vaccinesStipulate that all patients meeting certain criteria

should be vaccinated – age, underlying medicalcondition

Components1. Nurse/MA tracks immunization history2. Nurse/MA identifies eligible patients3. Nurse/MA educates patients –alert provider if

patient still has questions or wants to talk with theprovider

4. Nurse administers vaccines

Benefits of Standing Orders

Shown to be effective in both adults and children For children, use of standing orders is associated witha

median increase in vaccination coverage of 28% Most effective evidence-basedmethod

Overcome administrative barriers and save time

Why Vaccinate at Ages 11-12?

Data Source: Dobson, Simon RM, et al., 2013

1) Better immune response

Graph Source: Rand CM et al., 2007; reprinted with author’s permission

Females

2) More chances to vaccinateEarly adolescents have 3 times more preventive care visits than late adolescents

Data Source: Finer, Lawrence B., and Jesse M. Philbin, 2013

Female

3) Lack of exposureU.S. Teen Sexual Activity

Percent of adolescents who have had sex

4) Long duration of immunity

No evidence of waning protection up to 10years after 3-dose schedule

Antibody kinetics with 2-dose schedules aresimilar, suggesting there will be similarprotection

Graph Source: Gertig DM, 2013

Percent reduction in cervical dysplasia 5 years after vaccination, by age at vaccination

Age at introduction of vaccination

5) Prevents twice as much pre-cancer

What I say to patients:

“The HPV vaccine works better and prevents more cancers at younger ages.

If Ella gets the vaccine today she will only need 2 doses, but if we wait until she’s older she may need 3 doses.”

Why NOT Vaccinate at Ages 9 - 10?

You can’t vaccinate too early….. Only too late
