Our Goals for Today

Expand your understanding of the impact of HAV and HBV infection,
including transmission rates, clinical features, and risk factors for severe
disease and poor outcomes

Provide you with ACIP updated guidelines for HAV and HBV vaccination
Improve your ability to use professional-patient dialogue regarding HAV
and HBV vaccine recommendations to address disparities and barriers

in diverse adult populations

Equip you with multidisciplinary, interprofessional strategies for optimal
prevention of HAV and HBV infection in accordance with updated guidelines

Epidemiology and Burden of Hepatitis B in the United States!

Up to 2.4 million people are chronically infected
Rates of acute hepatitis B infection have risen 50%-450% in states impacted by the opioid crisis

For many countries, chronic hepatitis B rates are higher in men than women and have declined over
the past 3 decades, but no consistent pattern is seen between rates for US immigrants and residents

More than 50% of people living with chronic hepatitis B are of Asian, Pacific Islander, or African descent;
hepatitis B and the resulting liver cancer are among the largest health disparities for these groups

The weighted average chronic hepatitis B prevalence for all foreign-born people in the United States
in 2018 was about 3%

= About 59% of those US residents with chronic hepatitis B in the United States in 2018 emigrated
from Asia, 19% from the Americas, and 15% from Africa

Only 25% of infected individuals are diagnosed
Thousands of people die each year from hepatitis B

Transmission of HBV Infection’

+ Most common route of transmission is from mother to neonate (vertical transmission) or
from mother to child or child to child (horizontal transmission)

+ HBV is transmitted through percutaneous or mucosal contact with blood or body fluids

Others routes include

+ Sex with a partner who has HBV infection

+ Injection drug use that involves sharing needles, syringes, or drug preparation equipment
+ Accidental exposures to needle sticks or sharp instruments

+ Contact with blood from, or open sores on, a person who has HBV infection

+ Administration of contaminated blood products, especially in resource-restricted countries

ACIP Policy Statement for PreHevbrio, Added February 20221

PreHevbrio may be used as a HepB vaccine

Recommendation in persons aged 218 years recommended
for vaccination against HBV infection.

Persons on hemodialysis, pregnant persons,
and persons who are breastfeeding are not discussed
in this Evidence to Recommendations Framework.
The safety and effectiveness of PreHevbrio have not been established in adults
on hemodialysis. There are no adequate and well-controlled studies of
PreHevbrio in pregnant women. Available human data on PreHevbrio
administered to pregnant women are insufficient to inform vaccine-associated
tisks in pregnancy. Data are not available to assess the effects of PreHevbrio
on the breastfed infant or on milk production/excretion.

Viral Hepatitis: National Strategic Plan!
A Roadmap to Elimination for the United States, 2021-2025

The Need to Address Social Determinants of Health and Priority Populations

Many populations
disproportionately impacted by
viral hepatitis have faced
disparities in health status related
to the social determinants of

health, such as low-paying or
inconsistent employment, unstable
housing or homelessness, race,
ethnicity, and geographic location,
or other characteristics linked to
discrimination, stigma, or exclusion

Negative interactions with the
healthcare or social services
system may decrease the
likelihood of care-seeking
behavior, making viral hepatitis
risk assessment and linkage
to care, prevention, and treatment
more difficult; this difficulty poses
additional and unique challenges
to the development
of broad-based solutions

Reasons for Vaccine Hesitancy!

Concerns about vaccine safety, adverse effects, toxicity, or poor quality of vaccine components
Previous experiences with vaccines and interactions with healthcare providers

Mistrust of doctors, health authorities, government sources, pharmaceutical companies and scientific
research, and doubts about the technology used to produce the vaccine

Perceptions of low risk of contracting illness, low illness severity, and low vaccine efficacy

Lack of information, information sources, and influence of antivaccine proponents
Religious beliefs,

Desire for a “natural” and “organic” lifestyle

How a person’s peer group perceives vaccines

Belief in a person's right to make their own healthcare decisions

Fear of needles

Inconvenience

Vaccine cost

Strategies for Addressing Vaccine Hesitancy!

Listen to the patient and acknowledge their
concems without judgment

Engage the patient in a dialogue; frame the
conversation beyond a binary yes/no
vaccination decision

Tailor your response to the patient's
concems

Keep messages clear and easy
to understand

Avoid jargon

Avoid using statements such as “no risk,” as
people mistrust strong statements and may
conversely believe the opposite

Help patients to weigh up the risks versus
benefits

Remind patients of the benefits
of vaccinations, the mildness of vaccine
adverse effects, and the very low risk
of serious adverse effects

Highlight the risks of not immunizing

Do

Correct misinformation, accept questions,
and explain

Provide personal examples
(e, pharmacist's own vaccination,
fact sheets, and other resources)

‘Communicate the high level
of endorsement of vaccines by various
‘communities

Refer patient to other providers or schedule
another appointment to discuss remaining,
vaccination concerns

Guide patient along the vaccine hesitancy
continuum toward acceptance, and
recognize the value of the conversation,
even if patient does not get vaccinated

at that appointment

D

Question an individual's sacred values:
or group identity

Griicize a particular group, such as
vaccine-hesitant parents

Get into an argumentidebate back and forth
or repeat vaccine myths (as the person will
‘not remember a detailed explanation of why
the vaccine myth is incorrect but will
remember the simple narrative of the myth)

Use fear, as this can backfire

‘Overload the patient with information,
as this can backfire

Improving Vaccine Rates:

Defining Roles of Genera

Administer HAV and HBV vaccines as part
of routine preventive care

Identify patients at high risk for HAV and
HBV and screen for high-risk factors
such as travel to endemic areas and
lifestyle risks

Provide patient education

Monitoring and follow-up

ts and Specialists

Specialists

Conduct detailed assessments for patients
with complex or high-risk conditions
(eg, liver disease, HIV, those undergoing

immunosuppressive therapy)

Specialized vaccination protocols for
high-risk patients (considering factors
such as immune status, potential
nonresponsiveness, severe allergies, or
other contraindications)

Management of any vaccine-related
complications

Copyright © 2000-2024, PeerView

Working Together to Improve Vaccine Rates:
Generalists and Specialists

Generalists and specialists can form integrated care teams to ensure comprehensive care
for high-risk patients

Regular communication and coordinated care plans can ensure that vaccination and
follow-up are seamlessly managed

Shared EHRs to track patients’ vaccination histories and status

Provide patient education and involve patients in shared decision-making

Specialists can provide education to generalists to enhance their ability to identify and
manage high-risk patients

Collaborate on targeted outreach programs for high-risk populations

The Role of the Pharmacist in Increasing Vaccine Uptake’

Pharmacists have the potential to substantially increase the nation’s capacity to provide the HBV vaccine
| to high-risk populations
Rise of acute HBV infections is associated with the opioid crisis and ~10% of these acute infections will
result in chronic HBV infections
— Pharmacists have already been called upon to play a greater role in addressing the needs of patients
with opioid use disorder

Pharmacists can identify methods for improving HBV vaccine services in the community pharmacy
setting (eg, providing reminders)

A study to determine the impact of community pharmacist-Ied motivational interviewing (MI) on HBV
vaccination initiation among previously unvaccinated adults with diabetes found
— A statistically significant 3.711% increase in HBV vaccination when comparing eligible individuals who
received MI to eligible individuals in the control group
— Among patients in the MI group who initiated HBV vaccination, 61.5% completed the vaccination series

Summary

+ There have been ongoing outbreaks of HAV in the United States since 2016

— There has been difficulty reaching and vaccinating groups that are more
likely to be infected with HAV (eg, those who use drugs, homeless)
+ Rates of acute HBV have risen in states affected by the opioid crisis, and up to
2.4 million people are chronically infected
+ CDC’s Viral Hepatitis 2025 Strategic Plan aims to reduce new HAV infections
by 240% and new HBV infections by 220%

A universal HBV vaccination recommendation could help reduce disparities
in vaccination rates

An interprofessional approach can also help address disparities and improve
vaccination rates
