Back to the Future?Pre-Event Smallpox Vaccination

Is it safe to defer pre-event vaccination? Vaccination within 3 days of exposure to

a case prevents or significantly mitigates disease

IDPH and the Governor have prioritized health-care worker vaccinations in the setting of a smallpox outbreak

30% of young adults vaccinated in the fall of 2001 at the CDC had to take 2 days off due to side effects of the vaccine

Page 3: Back to the Future? Pre-Event Smallpox Vaccination John R. Lumpkin, MD, MPH, FACEP Illinois Department of Public Health.

What’s the purpose of Phase I vaccination? Immunize public health and health-

care workers who might be exposed to some of the earliest smallpox cases or be essential in caring for them

Phase I will not immunize all health-care workers who may or will be exposed to a smallpox case

HICPAC-ACIP RecommendationsOctober 2002

Smallpox Health Care Teams (SHCTs)

Screening for contraindications Vaccination site care Administrative leave

Page 5: Back to the Future? Pre-Event Smallpox Vaccination John R. Lumpkin, MD, MPH, FACEP Illinois Department of Public Health.

HICPAC: SHCTs

Each acute care hospital should identify a SHCT

Purpose of the SHCT Evaluate and manage patients in

the ED Provide in-room care for first 7 to

10 days Need to cover all shifts

Page 6: Back to the Future? Pre-Event Smallpox Vaccination John R. Lumpkin, MD, MPH, FACEP Illinois Department of Public Health.

HICPAC: SHCTs (cont’d)

ED and ICU physicians and nurses, including pediatric expertise

General medical staff, including ob and surgeons

House staff Subspecialists (ID, dermatologists,

pathologists) Infection control professionals Respiratory therapists, radiology

technicians, environmental services

HICPAC: SHCTs (cont’d)

“Although it is not recommended that emergency medical technicians (EMTs), as a group, be vaccinated in this first phase, individual hospitals may identify and include hospital-based EMTs (i.e., personnel who would be dispatched to transport patients with suspected smallpox)”

Page 8: Back to the Future? Pre-Event Smallpox Vaccination John R. Lumpkin, MD, MPH, FACEP Illinois Department of Public Health.

HICPAC-ACIP: Site Care

Daily dressing checks by staff designated by the hospital

“Health-care workers involved in direct patient care should keep their vaccination sites covered with gauze…and a semi-permeable dressing …until the scab separates.”

At home: gauze dressing

Page 9: Back to the Future? Pre-Event Smallpox Vaccination John R. Lumpkin, MD, MPH, FACEP Illinois Department of Public Health.

HICPAC-ACIP:administrative leave “Administrative leave is not required

routinely for newly vaccinated healthcare workers unless they are physically unable to work…or if they do not adhere to the recommended infection control precautions.”

“It is important to realize that the very close contact required for transmission of vaccinia to household contacts is unlikely to occur in the healthcare setting.”

Pre-event contraindications1. Pregnancy: current or planned within 4

weeks

2. Breast-feeding

3. Immunosuppression (including immunosuppressive diseases [HIV], conditions [lupus], therapies [post-transplant])

Page 11: Back to the Future? Pre-Event Smallpox Vaccination John R. Lumpkin, MD, MPH, FACEP Illinois Department of Public Health.

Pre-event contraindications (cont’d)4. Eczema or atopic dermatitis

5. Serious skin conditions not under control (psoriasis, severe acne, large burns, etc)

6. Close contact with people who have conditions noted in numbers 1 through 5

Page 12: Back to the Future? Pre-Event Smallpox Vaccination John R. Lumpkin, MD, MPH, FACEP Illinois Department of Public Health.

Pre-event contraindications (cont’d)6. Significant allergies to any of the

antibiotics used in the manufacture of the vaccine (streptomycin, tetracycline, chloramphenicol) or latex

7. Close contact with children less than 1 year old

Page 13: Back to the Future? Pre-Event Smallpox Vaccination John R. Lumpkin, MD, MPH, FACEP Illinois Department of Public Health.

Implementation of Phase I Exact date still uncertain IDPH will receive the vaccine and

distribute to local health departments (LHDs)

LHDs will establish vaccination clinic hours, administer vaccine

Follow-up (dressing checks and assessment of “take”) at the hospital

Page 14: Back to the Future? Pre-Event Smallpox Vaccination John R. Lumpkin, MD, MPH, FACEP Illinois Department of Public Health.

What will happen at the vaccination clinic? Volunteers will watch a 20 minute

video provided by the CDC Volunteers will be asked to sign an

informed consent form Vaccination given intradermally

above right deltoid Vaccinees given site instructions

and proof-of-vaccination card

Page 15: Back to the Future? Pre-Event Smallpox Vaccination John R. Lumpkin, MD, MPH, FACEP Illinois Department of Public Health.

Follow-up

Each hospital will designate a hospital-assigned physician (HAP); this person will be your resource if you have questions prior to vaccination or complications after

Page 16: Back to the Future? Pre-Event Smallpox Vaccination John R. Lumpkin, MD, MPH, FACEP Illinois Department of Public Health.

Expected Side Effects

Temp up to 102º Malaise Erythema, tenderness up to10 cm Axillary adenopathy 30% of the young adults vaccinated at

the CDC in the fall of 2001 had to take 1-2 days off because of side effects; this peaked at day 8 after the vaccination

Page 17: Back to the Future? Pre-Event Smallpox Vaccination John R. Lumpkin, MD, MPH, FACEP Illinois Department of Public Health.
Page 18: Back to the Future? Pre-Event Smallpox Vaccination John R. Lumpkin, MD, MPH, FACEP Illinois Department of Public Health.

Assessing “take”

The HAP at each hospital will evaluate “take” on day 7, 8, 9, or 10 after vaccination

Page 19: Back to the Future? Pre-Event Smallpox Vaccination John R. Lumpkin, MD, MPH, FACEP Illinois Department of Public Health.

Complications

1000 per every million vaccinees in the past Most common complications:

autoinnoculation and disseminated vaccinia, both usually self-limited and insignificant

Eczema vaccinatum (30:1,000,000) Progressive (necrotizing) vaccinia in

people with cellular immunodeficiencies 1 death per million for first time

vaccinees; 1 in 4 million for previously vaccinated

Page 20: Back to the Future? Pre-Event Smallpox Vaccination John R. Lumpkin, MD, MPH, FACEP Illinois Department of Public Health.

Liability Issues

People administering vaccine protected by Homeland Security Act

Vaccinees who inadvertently innoculate another person (patient, household contact)--HSA does not offer liability protection

Compensation for days off due to expected side effects?

Page 22: Back to the Future? Pre-Event Smallpox Vaccination John R. Lumpkin, MD, MPH, FACEP Illinois Department of Public Health.

Miscellaneous information Duration of immunity: 3 to 5 years (you’ll

need to be revaccinated if smallpox remains a threat)

What about the “new” vaccine? It will still be a live virus, just produced in cell culture instead of on the side of a cow.
