To inform policy-makers about introduction of preventive interventions against typhoid, including vaccination.A population-based prospective surveillance design was used. Study sites where typhoid considered a problem by local authorities were established in China, India, Indonesia, Pakistan and Viet Nam. Standardized clinical, laboratory, methods used to investigate cases fever >or= 3 days' duration for one-year period. A total 441,435 persons under surveillance, 159,856 whom aged 5-15...
The SARS-CoV-2 pandemic has revealed the vulnerability of immunisation systems worldwide, although scale these disruptions not been described at a global level. This study aims to assess impact COVID-19 on routine using triangulated data from global, country-based, and individual-reported sources obtained during period.
Endorsed by the World Health Assembly in 2020, Immunization Agenda 2030 (IA2030) strives to reduce morbidity and mortality from vaccine-preventable diseases across life course (1). This report, which updates a previous report (2), presents global, regional,* national vaccination coverage estimates trends as of 2020. Changes are described numbers unvaccinated undervaccinated children measured receipt first third doses diphtheria, tetanus, pertussis-containing vaccine (DTP) when COVID-19...
In 2020, the World Health Assembly endorsed Immunization Agenda 2030, an ambitious global immunization strategy to reduce morbidity and mortality from vaccine-preventable diseases (1). This report updates a 2020 (2) with global, regional,* national vaccination coverage estimates trends through 2021. Global of 3 doses diphtheria-tetanus-pertussis-containing vaccine (DTPcv3) decreased average 86% during 2015-2019 83% in 81% Worldwide 2021, 25.0 million infants (19% target population) were not...
In 2020, the World Health Assembly endorsed Immunization Agenda 2030 (IA2030), 2021-2030 global strategy that envisions a world where everyone, everywhere, at every age, fully benefits from vaccines. This report reviews trends in Organization and UNICEF immunization coverage estimates global, regional, national levels through 2022 documents progress toward improving with respect to IA2030 strategy, which aims reduce number of children who have not received first dose...
In 1974, the World Health Organization (WHO) established Expanded Program on Immunization* to provide protection against six vaccine-preventable diseases through routine infant immunization (1). Based 2015 WHO and United Nations Children's Fund (UNICEF) estimates, global coverage with third dose of diphtheria-tetanus-pertussis vaccine (DTP3), first measles-containing (MCV1) polio (Pol3) has remained stable (84%-86%) since 2010. From 2014 2015, estimated second MCV (MCV2) increased from 39%...
Concerns about the quality and use of immunization vaccine-preventable disease (VPD) surveillance data have been highlighted on global agenda for over two decades. In August 2017, Strategic Advisory Group Experts (SAGE) established a Working (WG) onthe Quality Use Global Immunization Surveillance Data to review current status evidence make recommendations, which were presented SAGE in October 2019. The WG synthesized from landscape analyses, literature reviews, country case-studies,...
The COVID-19 pandemic has contributed to the widespread disruption of immunization services, including postponement mass vaccination campaigns.In May 2020, World Health Organization and partners started monitoring COVID-19-related disruptions campaigns against cholera, measles, meningitis A, polio, tetanus-diphtheria, typhoid, yellow fever through Immunization Repository Campaign Delay Tracker. authors reviewed number target population reported preventive outbreak response scheduled,...
Data from the WHO and UNICEF Estimates of National Immunization Coverage (WUENIC) 2022 revision were analyzed to assess status routine immunization in African Region disrupted by COVID-19 pandemic. In 2022, coverage for first third doses diphtheria–tetanus–pertussis-containing vaccine (DTP1 DTP3, respectively) dose measles-containing (MCV1) region was estimated at 80%, 72% 69%, respectively (all below 2019 level). Only 13 47 countries (28%) achieved global target 90% or above with DTP3 2022....
In 2020, the World Health Assembly endorsed Immunization Agenda 2030 (IA2030), a 10-year strategy to reduce vaccine-preventable disease (VPD)-associated morbidity and mortality. IA2030 goals include improving equitable vaccination coverage, halving number of unimmunized (zero-dose) children, increasing introduction new underutilized vaccines. The COVID-19 pandemic disrupted health systems worldwide, hindering years childhood achievements putting global public at risk. This report presents...
In Latin America and the Caribbean, rotavirus causes approximately 15,000 deaths, 75,000 hospitalizations, 2 million clinic visits 10 cases of diarrhea annually. Two safe vaccines are available that effective in preventing severe illness. To date, seven countries (Brazil, Ecuador, El Salvador, Panama, Mexico, Nicaragua Venezuela) have introduced vaccine. For successful vaccine introduction, lessons learned re-emphasize critical need for to precise plans will ensure technical, programmatic...
There has been considerable uptake of seasonal influenza vaccines in the Americas compared to other regions. We describe current vaccination target groups, recent progress vaccine and generating evidence on seasonality effectiveness for immunization programs. also discuss persistent challenges, 5 years after A(H1N1) 2009 pandemic.We compiled summarized data annually reported by countries Pan American Health Organization/World Organization (PAHO/WHO) through WHO/UNICEF joint report form...
Measles vaccination campaigns are conducted regularly in many low- and middle-income countries to boost measles control efforts accelerate progress towards elimination. National sometimes first-level administrative division campaign coverage may be estimated through post-campaign surveys (PCCS). However, these large-area estimates mask significant geographic inequities at more granular levels. Here, we undertake a geospatial analysis of the Nigeria 2017–18 PCCS data produce 1 × km resolution...
The goal of eliminating indigenous rubella and congenital syndrome (CRS) in the United States near future is now within reach, because incidence has been sustained at record-low levels since mid-1990s. Effective prevention strategies to eliminate CRS require improvement surveillance infection (CRI). purpose workshop was review epidemiology, as well current clinical, diagnostic, laboratory practices, determine whether new are needed achieve document elimination. Workshop participants agreed...
<b>Aims:</b> To conduct a prospective, community based study in an impoverished urban site Kolkata (formerly Calcutta) order to measure the burden of cholera, describe its epidemiology, and search for potential risk factors that could be addressed by public health strategies. <b>Methods:</b> The population was enumerated at beginning end period.

Oral cholera vaccines (OCVs) have been recommended in cholera-endemic settings and preemptively during outbreaks complex emergencies. However, experience guidelines for reactive use after an outbreak has started are limited. In 2010, over a century without epidemic cholera, was reported Haiti earthquake. As intensive nonvaccine control measures were initiated, the feasibility of OCV considered. We reviewed characteristics recommendations their assessed global vaccine availability capacity to...
