Some Considerations • The disease • The risk of an attack • The public health impact of an attack • The medical literature • Current recommendations • Questions for today
The Disease • Easily spread: Most infectious disease • Significant morbidity and mortality • 500 million deaths in 20th century • 2 million deaths in 1967 • Real morbidity
The Risk of an Attack • 1980: Soviet Union starts Smallpox weapons program • 1986: WHO recommends destruction of existing virus stocks • 1994: Alibek defects, former deputy director of Soviet bioweapons program
The Risk of an Attack • USSR producing “tons of virus” • Successful weaponization of smallpox accomplished • Virus transferred to a facility in Siberia • Occurred concurrent with serious economic problems in Russia • Might other countries might acquire the technology and weapons?
Public Health Implicationsof a Smallpox Attack • 1972: Yugoslavia • 1 case identified • 11 people infected • 138 people then infected • 10,000 people isolated • 20,000,000 people vaccinated
The Medical Literature • NEJM • Early release of articles • Free distribution of materials • Six articles • Public, risk, vaccination, public health • Good information for framing discussion
NEJM: Schraeder • Obligation to protect public health • Public health decisions • “Trust our heads and our hearts”
NEJM: Blendon • Public knowledge unclear • Survey of 1006 adults • False smallpox vaccination beliefs • Need for public education
NEJM: Bozzette • Scenarios of smallpox attacks • Stochastic model of outcomes • Risk of attack, risks of vaccination • No risk: no vaccination • Some risk: vaccinate HCWs • High risk: vaccinate public
NEJM: Sepkowitz • How contagious is vaccinia? • 1907-1975: • 12 outbreaks • 85 secondary cases • 75%: young children, atopic dermatitis • Immunocompromise in HCWs • Risk of hospital vaccinia outbreak
NEJM: Mack • Alternate view of minimizing risk • Vaccination & immunoglobulin best • High risk of attack: immunize • Otherwise, go for safer options • Facilitate rapid diagnosis • Use alternate medical facilities • Vaccinate and train 15,000 in US • Have vaccinia IgG for complications • Educate in a less inflammatory way
NEJM: Hanrahan • Smallpox false alarm: case report • Papulovesicular rash, same stages • Centrifugal distribution • Prodrome with fever, N/V • CDC specimens: HSV positive • Hospital test for HSV, VZV, syphillis • Digital camera for email to CDC
Current Recommendations • CDC Advisory Committee on Immunization Practices (ACIP) • June 2001: Initial recommendations • June 2002: “Smallpox Health Care Teams” • October 2002: 8 Specific Issues • Comment: CDC HICPAC, DHHS NVAC
ACIP Recommendations • Smallpox health care teams • Smallpox vaccination site care • Phase in: no administrative leave • Screen: atopic dermatitis, pregnancy, HIV • Administer other vaccinations • Vaccinate the vaccinators
Questions for Today • Knowns: • Risk of disease • Risk of vaccination • Unknowns: • Risk of attack • Effect in society with immunocompromise • Public health value of vaccination • Need for vaccination
Questions for Today • What are the risks of attack in 2003? • What are the risks of vaccination? • Who should get vaccinated? • Who should get vaccinated first? • Does prior vaccination matter? • What happens after vaccination? • Who assumes liability of vaccination?
Questions for Today • What does the state expect of us? • What are hospitals doing? Why? • What are the risks of vaccination? • What do we need to get it done? • What are our knowledge gaps • What comes next?
Our Speakers • Patricia Lee, MD • Advocate IMMC • Smallpox and vaccination • Dino Rumoro, DO • Rush-Pres-St Luke • Hospital perspective • John Lumpkin, MD, MPH • Illinois Dept of Public Health • State public health perspective
Format & Information • Three 20 minute lectures • Opportunity for questions • Videostreamed content • Slides and lectures on internet • www.FERNE.org • Link from www.ICEP.org
