The European Regional Office of WHO has targeted measles for elimination from the region in 2007. Large national, age and sex stratified serological surveys of measles antibody were conducted in seven Western European countries from 1994-8 as part of the European Seroepidemiology Network. Three patterns were observed in the country-specific measles seroprofiles, ranging from (very) low suscepti...
INTRODUCTION Influenza is a considerable health problem all over the world. The most important group for influenza vaccination are children: the highest attack rate during community out-breaks of influenza can be found among school-aged children or their family members; children bear a considerable risk for complications due to influenza, leading to an increased need for healthcare resources (i...
Africa has the lowest childhood vaccination coverage worldwide. Background If the full benefits of childhood vaccination programmes are to be enjoyed in sub-Saharan Africa, all countries need to improve on vaccine delivery to achieve and sustain high coverage. In this paper, we review trends in vaccination coverage, dropouts between vaccine doses and explored the country-specific predictors of ...
BACKGROUND Serogroup distribution of sterile site pneumococcal isolates varies between developing and developed countries as well as between different geographical regions. The potential efficacy of any pneumococcal vaccine depends on the degree of representation of the prevalent serogroups in the vaccine. We conducted this study to determine the prevalent pneumococcal serogroups causing invasi...
Vaccinations are recommended throughout life to prevent vaccine-preventable diseases and their sequelae. Adult vaccination coverage, however, remains low for most routinely recommended vaccines and well below Healthy People 2020 targets. In October 2012, the Advisory Committee on Immunization Practices (ACIP) approved the adult immunization schedule for 2013. Apart from influenza vaccination, w...
We conducted a multi-stage household cluster survey to calculate hepatitis B vaccine coverage among children 18-30 months of age in 27 Brazilian cities. Hepatitis B vaccine is administered at birth, 1 month and 6 months of age by Brazil's national immunization program. Among 17,749 children surveyed, 40.2% received a birth dose within one day of birth, 94.8% received at least one dose of hepati...
background: re-emergence of pertussis has been reported in iran despite a high rate of vaccination coverage. low efficacy of the vaccine might be due to the genetic divergence between clinical versus vaccine strains. in the current study, the genetic profiles of clinical isolates and vaccine strains of bordetella pertussis (b. pertussis) were assessed by using pulsed field gel electrophoresis (...
BACKGROUND Substantial outbreaks of yellow fever in Angola and Brazil in the past 2 years, combined with global shortages in vaccine stockpiles, highlight a pressing need to assess present control strategies. The aims of this study were to estimate global yellow fever vaccination coverage from 1970 through to 2016 at high spatial resolution and to calculate the number of individuals still requi...
This paper describes a possible multifaceted approach to human papillomavirus (HPV) related surveillance in Australia following implementation of a national HPV vaccination program. We describe eight main components: monitoring of vaccine coverage, vaccine safety, type-specific HPV infection surveillance, cervical cytology (Pap screening) coverage and screen detected lesion prevalence, cervical...
