Who’s at Risk?Who’s at Risk?

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.

How is it diagnosed?How is it diagnosed? Multiple tests may be required to accurately

diagnose disease Frequent incorrect diagnoses:

Culture and PCRCulture and PCR

Nasopharyngeal (Dacron) swab or aspirate is the preferred sample

It’s the nasopharynx we’re after

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 employees:

TOTAL COST incurred:

Cost of 1 dose of Tdap:

$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
