In this paper, we analyze the temporal evolution of the age-dependent force of infection and incidence of rubella, after the introduction of a very specific vaccination program in a previously nonvaccinated population where rubella was in endemic steady state. We deduce an integral equation for the age-dependent force of infection, which depends on a number of parameters that can be estimated f...

BACKGROUND Over the past four decades, the World Health Organization established the Expanded Programme on Immunization (EPI) to foster universal access to all relevant vaccines for all children at risk. The success of this program has been undeniable, but requires periodic monitoring to ensure that coverage rates remain high. The aim of this study was to measure the BCG vaccination coverage in...

National programmes of hepatitis B virus (HBV) vaccination are recommended by the World Health Organization for all countries. Countries suffering the highest burden of HBV disease are those most needy of universal vaccination, but are frequently of very low income and resources for health care are scarce. The introduction of HBV vaccination would inevitably stretch these resources further even...

Meeting the health needs of adolescents who live in high-risk settings such as homeless shelters, migrant camps, juvenile detention centers, prisons, and other types of residential facilities presents many challenges. Although there is no doubt that adolescents in many high-risk settings are at increased risk for hepatitis B and human papillomavirus, acute medical and psychological problems may...

Adolescent attitudes toward influenza vaccination may play a key role in reaching this newly added age group. This study examined the association between attitudes toward influenza v...

BACKGROUND Similar to many developed countries, vaccination against human papillomavirus (HPV) is provided only to girls in New Zealand and coverage is relatively low (47% in school-aged girls for dose 3). Some jurisdictions have already extended HPV vaccination to school-aged boys. Thus, exploration of the cost-utility of adding boys' vaccination is relevant. We modeled the incremental health ...

BACKGROUND There has been considerable uptake of seasonal influenza vaccines in the Americas compared to other regions. We describe the current influenza vaccination target groups, recent progress in vaccine uptake and in generating evidence on influenza seasonality and vaccine effectiveness for immunization programs. We also discuss persistent challenges, 5 years after the A(H1N1) 2009 influen...
