Adult Immunization: An Unexploited Opportunity for Prevention
Adult immunization presents a crucial opportunity for prevention of vaccine-preventable diseases, with significant morbidity and mortality affecting adults. Despite successful outcomes in childhood vaccinations, adult vaccine coverage remains suboptimal, highlighting the need for advocacy and awareness. Investing in adult immunization can lead to substantial savings in healthcare costs and improved public health outcomes.

ADULT IMMUNIZATION An Unexploited Opportunity for Prevention William Schaffner, MD Professor of Preventive Medicine Department of Health Policy Professor of Medicine (Infectious Diseases) Vanderbilt University School of Medicine Nashville, TN
It is better to avert the malady by care than to have to apply physic after it has appeared. Shao Tze
CDCs Advisory Committee on Immunization Practices
Immunization Successes Selected as one of 10 great public health achievements of the 20thcentury Smallpox eradication (globally) Polio elimination (most of the world) Measles elimination (western hemisphere) Rubella elimination (western hemisphere) CDC, MMWR 1999;48:241-243
Estimated Return on Investment of Childhood Vaccines For each birth cohort vaccinated against 13 diseases in accordance with the schedule of DTaP, Hib, IPV, MMR, Hep B, Varicella, Hep A, Pneumo-7, and Rotavirus vaccines: 42,000 lives are saved 20M cases of disease are prevented 13.6 billion dollars in direct costs are saved 68.9 billion dollars in direct plus indirect (societal) costs are saved For each dollar invested in these vaccinations, $10.20 is saved See presentation: by Fangjun Zhou Tuesday Mar 29, Workshop D2 11:30am Preliminary results of updated analysis from Zhou et al, Arch of Ped and Adolesc Med 2005
Invigoration of Adult Immunization Build on success of infant/childhood, adolescent program New vaccines targeted at adults Recognition of the burden of adult vaccine- preventable disease the majority of cases and deaths due to vaccine-preventable diseases now occur in adults
Adult Immunization Concepts The vast majority of vaccine-preventable diseases occur in adults These diseases produce substantial morbidity and mortality Vaccine coverage of adults is suboptimal, with notable disparities of race/ethnicity and income Your advocacy for vaccines will benefit your patients Centers for Disease Control and Prevention (CDC). MMWR Morb Mortal Wkly Rep. 2012;61(04):66-72.
Immunization Contrasts - 1 Pediatric Adult Diseases distinctive Fabulous vaccines Interrupt transmission Eliminate disease Universal coverage Active programs: find everyone National/global vision Diseases not as distinctive Good vaccines Personal protection Reduce risk Targeted populations Passive: try to immunize those presenting for care Focus on practice
Immunization Contrasts - 2 Pediatric Adult Create hurdles: no shots, no school Recommendations clearly communicated Funding rather secure Averse to hurdles Recommendations inadequately communicated Funding less certain
CORE ADULT VACCINES INFLUENZA PNEUMOCOCCAL TDAP/TD ZOSTER HEPATITIS B HPV
Burden of Vaccine-Preventable Diseases 1 United States/Annual Rates 200,000 hospitalizations 36,000 deaths (>85% elderly) INFLUENZA 44,000 cases 4500 deaths Higher rates in elderly, AA, persons with comorbidities INVASIVE PNEUMOCOCCAL DISEASE 51,000 infections (>95% adults) 2000-3000 deaths 1.25 (m) chronic HBV infection HEPATITIS B AA, African American; HBV, hepatitis B virus.

Burden of Vaccine-Preventable Diseases 2 United States/Annual Rates 6.2 million new infections 2 HPV strains cause 70% of cervical cancers and most anal, head and neck cancers HUMAN PAPILLOMAVIRUS (HPV) Outbreaks throughout US adolescents and young adults Most severe in infants Source is usually an adult or older child PERTUSSIS Centers for Disease Control and Prevention. http://www.cdc.gov/.
Burden of Vaccine-Preventable Diseases 3 United States/Annual Rates 1 (m) cases Lifetime risk 30% Incidence of shingles and postherpetic neuralgia increases with age SHINGLES Centers for Disease Control and Prevention. http://www.cdc.gov/.

Reasons Why Patients Not Vaccinated Healthy, don t think they need it Didn t know about disease Didn t know about vaccine Doctor didn t recommend it
When It Comes to Vaccines, Doctors and Patients Aren t Hearing One Another Most physicians say, I talk to all of my patients about vaccines But few patients agree 87% I occasionally discuss vaccines with my health care provider Yes, I regularly discuss vaccines with my health care provider I don't recall ever discussing vaccines 31% 21% 18% Physicians Patients Results are based on surveys by the National Foundation for Infectious Diseases.

BE AN ADVOCATE FOR VACCINATING YOUR ADULT PATIENTS!
When meditating over a disease, I never think of finding a remedy for it, but instead, a means of preventing it. -Louis Pasteur
