In the event of a smallpox bioterrorist attack in a large U.S. city, the interim response policy is to isolate symptomatic cases, trace and vaccinate their contacts, quarantine febrile contacts, but vaccinate more broadly if the outbreak cannot be contained by these measures. We embed this traced vaccination policy in a smallpox disease transmission model to estimate the number of cases and dea...

Concerns over bioterrorism and emerging diseases have led to the widespread use of epidemic models for evaluating public health strategies. Partly because epidemic models often capture the dynamics of prior epidemics remarkably well, little attention has been paid to how uncertainty in parameter estimates might affect model predictions. To understand such effects, we used Bayesian statistics to...

BACKGROUND A quadrivalent human papillomavirus (HPV 6/11/16/18) vaccine has recently received regulatory approval in Taiwan for the prevention of cervical carcinoma, high-grade cervical dysplasia (cervical intraepithelial neoplasia 2/3 [CIN 2/3]), low-grade cervical dysplasia (CIN 1), high-grade vulvar and vaginal dysplasia, and external genital warts. OBJECTIVE To examine the potential long-...

A local general practice was contracted to provide the school-based immunisation program over two years in Mount Isa, Queensland. The schedule was for female Year 10, 11 and 12 students to receive three doses of human papilloma virus (HPV) vaccination (Gardasil). This was provided as part of the broader immunisation program that involved providing Year 8 students with two doses of hepatitis B v...

The Korean influenza national immunization program was first established as an interim program in 1997, administering the influenza vaccine to low-income elderly adults. In 2005, the program assumed its present form of providing free influenza vaccination to adults aged ≥65 years. After turning over the influenza vaccination for elderly adults to the private sectors in 2015, the influenza vacci...

CONTEXT Recent anthrax attacks in the United States have raised concern about the nation's vulnerability to a smallpox attack. Many strategies have been suggested to minimize the impact of such an attack, ranging from quarantine and vaccination of case contacts to resumption of routine vaccination. Before the latter strategy is adopted, an understanding of the likely consequences of mass vaccin...
