Includes physicians, nurses, nursing/medical assistants, therapists, technicians, EMTs/Paramedics, dental, pharmacists, laboratory personnel, autopsy, students, trainees, contract staff, persons potentially exposed to infectious agents that can be transmitted to and from HCP
Settings include hospitals, nursing homes, skilled nursing facilities, physicians’ offices, urgent care centers, outpatient clinics, home healthcare, and emergency medical services
Adult Vaccines…Adult Vaccines… Shingles (Herpes Zoster)Shingles (Herpes Zoster)
One dose of Herpes Zoster Vaccine (Zostavax) at age 60 or older
Effective even if they’ve had a history of shingles

2nd dose of MMR is recommended for HCP, or show lab evidence of immunity
MeaslesMeasles – Highly contagious virus found throughout the world, can remain airborne for up to 2 hours Transmission – coughing, sneezing or talking Symptoms – high fever, rash, runny nose, watery eyes, cough,
diarrhea & earache Incubation – 10 to 14 days

Facts vs. MythsFacts vs. Myths I get sick from the vaccineI get sick from the vaccine
MythThe influenza vaccine is made from a DEAD virusYou cannot get sick from itYou cannot get sick from itSide effects may include a low-grade fever and
muscle achesThe flu shot can take up to two weeks to
become effective so you can still get the flu or a flu-like illness during this time
Why I didn’t get a flu shot…Why I didn’t get a flu shot… My doctor didn’t recommend it
I am afraid of needlesThe flu shot is given with a relatively small needle. Check with your doctor to see if you are eligible to receive FluMist® - a vaccine that is sprayed into your nose and does not require needles.
The Flu isn’t that badInfluenza causes an average of 36,000 deaths and over 200,000 hospitalizations per year. Source: CDC Influenza Information

Nasal Spray (LAIV) - FluMist®Nasal Spray (LAIV) - FluMist® Live attenuated influenza vaccine No needles – spray mist into the nose Approved for healthy persons ages 2-49 years of age Slightly more expensive

How is it diagnosed?How is it diagnosed? Multiple tests may be required to accurately
diagnose disease Frequent incorrect diagnoses:
Asthma Gastroesophageal reflux Post-viral bronchospasm Chronic sinusitis Tuberculosis
Culture and PCRCulture and PCR
Nasopharyngeal (Dacron) swab or aspirate is the preferred sample
It’s the nasopharynx we’re after
Pertussis in AdultsPertussis in AdultsAdultsAdults: Are the main reservoirs of disease in areas
with high immunization coverage rates
Transmit primarily to non-immune children (≤ 1 year of age) or to adults whose immunity has waned

Costs of an OutbreakCosts of an Outbreak September 2003 – outbreak of pertussis in an
acute care facility 17 employees were infected Following a one-day exposure to an infant with
pertussis
Infection control measures were immediately implemented in hospital
Study examined outbreak-related costs and estimated possible benefits to vaccination
Study ResultsStudy Results
Cost incurred by the hospital:
Cost incurred by the employees:
TOTAL COST incurred:
Cost of 1 dose of Tdap:
$74,870$74,870
$6,512$6,512
$81,382$81,382
$37.00$37.00
CDC RecommendsCDC Recommends All HCP in hospitals, LTCF/SNF, ambulatory care and
emergency medical services (EMS) settings also receive Tdap in place of Td booster
Priority groups: HCP in contact with infants less than 12 months Emergency Departments Maternal/Child Health ICU/NICU Respiratory Therapy
All adults receive Tdap in place of their tetanus booster
Postpartum mothers and/or primary caregivers receive Tdap
CDC RecommendsCDC Recommends
Tdap VaccineTdap Vaccine
TTetanus etanus ddiphtheria iphtheria aacellular cellular ppertussisertussis
Licensed in 2005
Only one dose is required and it can be given in an interval as short as 2 years from the last Td booster
Tdap Adverse ReactionsTdap Adverse Reactions
Localized pain, redness, swelling
Low-grade fever
Adverse reactions occur at approximately the same rate as Td alone

A True Story…A True Story…
ConclusionsConclusions Vaccinating ADULTS with Tdap:
85% protection with vaccine! Protect your family from pertussis Prevent an outbreak in workplace thereby reducing
costs and minimizing sick leave
Keeping adults up to date with their vaccines can minimize the effects of vaccine-preventable diseases
