Smallpox
In response to concern about smallpox possibly being used as a biological weapon, the President of the United States launched the National Smallpox Pre-Event Vaccination Program on December 13, 2002. The journal Clinical Infectious Diseases published a special supplement entitled "Posteradication Vaccination against Smallpox"* on March 15, 2008. The 14 articles in this supplement describe the context in which the national smallpox vaccination program was implemented, and focus on the overall safety and effectiveness of the vaccine.
The following four articles explain the Immunization Safety Office's role in this initiative.
- "A Review of the Smallpox Vaccine Adverse Events Active Surveillance System," first-authored by ISO, explains how the Vaccine Adverse Event Reporting System (VAERS) helped monitor serious health problems among those vaccinated against smallpox as part of the National Smallpox Pre-Event Vaccination Program.
- "Ischemic Cardiac Events during the Department of Health and Human Services Smallpox Vaccination Program, 2003," co-authored by ISO, notes that out of 37,901 smallpox vaccinees, 10 had heart attacks ("ischemic cardiac events") within 28 days of vaccination. Seven of the 10 had three or more risk factors for a heart attack before vaccination. After people with three or more risk factors were excluded from receiving the smallpox vaccine, 6,638 more people were vaccinated, and none had heart attacks.
- "Myocarditis, Pericarditis, and Dilated Cardiomyopathy after Smallpox Vaccination among Civilians in the United States, January–October 2003," co-authored by ISO, explains the risk that people who are vaccinated against smallpox will have heart problems other than heart attacks. The article concludes that the risks are small, but that "future US smallpox vaccination programs should include education material, appropriate clinical follow-up, and adequate surveillance" to prepare for and respond to this risk.
- "A Process for Sentinel Case Review to Assess Causal Relationships between Smallpox Vaccination and Adverse Outcomes, 2003–2004," co-authored by ISO, reports the results of an investigation into the mysterious death of a young, previously healthy Army reservist a month after being vaccinated against smallpox, typhoid, anthrax, hepatitis B, measles, mumps, and rubella. The scientists were asked to determine if this death was related to the smallpox vaccination, and if so, if this death indicated the existence of an unknown vaccine-associated syndrome. After an extensive review, the authors "identified no pattern that justified recognition of a new possibly smallpox vaccine-associated clinical syndrome," and noted the need for further study on adult responses to multiple vaccines.
