Sustaining measles and rubella elimination through the Regional Monitoring and Re-Verification Commission in the Americas.

The elimination of endemic rubella and measles transmission in the Region of the Americas was verified by the Pan American Health Organization's (PAHO) Regional Verification Commission in 2015 and 2016, respectively. Upon achieving this success, this Commission was disbanded. Shortly afterwards, the Region faced challenges in the post-elimination era, notably responding to and stopping transmission of imported measles cases.

Accelerating Global Measles and Rubella Eradication-Saving Millions of Lives, Preventing Disability, and Averting the Next Pandemic.

No vaccine has been more effective in reducing disease burden, especially in preventing child deaths, than measles-containing vaccine. The return on investment makes measles-containing vaccine one of the most cost-effective public health measures available. Exhaustive reviews of biological, technical, economic and programmatic evidence have concluded that measles can and should be eradicated, and by including rubella antigen in measles-containing vaccine, congenital rubella syndrome will also be eradicated.

I am delighted and honored to be Guest Editor of this Special Issue on measles and rubella elimination [...

Sustaining the Elimination of Measles, Rubella and Congenital Rubella Syndrome in the Americas, 2019-2023: From Challenges to Opportunities.

This report reviews national data from all Member States on measles, rubella, and congenital rubella syndrome (CRS) elimination in the Region of the Americas during 2019-2023. It includes an analysis of compliance with vaccination coverage, surveillance indicators, and measles outbreaks, as well as an analysis of the response capacity of the laboratory network and a country case study that meets all indicators. The sources of information were the integrated epidemiological surveillance system for measles and rubella of the Pan American Health Organization (PAHO)/World Health Organization (WHO) and the Joint Reporting Form (eJRF), among others.

Measles and rubella elimination: protecting children through immunization in South-East Asia Region (SEAR).

The South-East Asia Region (SEAR) adopted the goal of "measles and rubella elimination by 2023". The goal was revised in 2019 to 'measles and rubella elimination by 2023' The strategies adopted to reach the goal included achieving ≥95% coverage with 2 doses of measles- and rubella-containing vaccine (MCV2; RCV2); establishing effective case-based surveillance supported by an accredited laboratory network; and implementing rapid response measures to control measles outbreaks. Of the 11 countries in the Region, to date five countries have eliminated measles and rubella and two more have controlled rubella.

Seasonal Influenza Prevention and Control Progress in Latin America and the Caribbean in the Context of the Global Influenza Strategy and the COVID-19 Pandemic.

Each year in Latin America and the Caribbean, seasonal influenza is associated with an estimated 36,500 respiratory deaths and 400,000 hospitalizations. Since the 2009 influenza A(H1N1) pandemic, the Region has made significant advances in the prevention and control of seasonal influenza, including improved surveillance systems, burden estimates, and vaccination of at-risk groups. The Global Influenza Strategy 2019-2030 provides a framework to strengthen these advances.

The ethical case for global measles eradication-justice and the Rule of Rescue.

Measles causes a substantial disease burden for all countries, while mortality is greatest in underserved, marginalized populations. Global measles eradication is feasible and the strategies critically rely upon well-functioning national immunisation programs and surveillance systems. All six regions of the World Health Organisation have adopted measles elimination targets.

Eradicating Measles: A Call for an Exceptional Coordinated Global Effort.

There are compelling epidemiological, economic, and ethical arguments for setting a global measles eradication goal. The 6 chairpersons of Regional Verification Commissions for Measles and Rubella elimination advocate that the time for courageously accelerating efforts to ensure a world where no child dies of measles, is NOW!

Knowing the scope of meningococcal disease in Latin America.

Opportunities for strengthening surveillance of meningococcal disease exist between and within countries in Latin America. In August of 2015, a workshop was convened in the city of São Paulo, Brazil, to address the following objectives: 1) to review meningococcal disease burden and vaccine use in Latin America; 2) to evaluate the effectiveness of current meningococcal surveillance practices in the region; 3) to identify challenges to meningococcal surveillance in the region; and 4) to outline steps for strengthening meningococcal surveillance and disease control in the region. Based on the workshop's discussions, recommendations for strengthening surveillance and controlling meningococcal disease in Latin America focus on improving: a) laboratory capabilities for diagnostic testing; b) communication regarding epidemiologic- and laboratory-based analyses; c) communication during outbreaks; d) monitoring of long-term disease outcomes; e) knowledge of vaccines against serogroup B disease; and f) criteria for defining and controlling meningococcal outbreaks.

National legislation and spending on vaccines in Latin America and the Caribbean.

This study examined the dynamics of vaccine spending and vaccine legislation in the Americas Region over the period 1980-2013. Annual vaccine expenditures from thirty-one countries were extracted from the Pan American Health Organization Revolving Fund database. Information on vaccine laws and regulations was provided by the PAHO Family, Gender, and Life Course Unit.

Impact of pneumococcal conjugate vaccine in children morbidity and mortality in Peru: Time series analyses.

Streptococcus pneumoniae is the leading cause of bacterial pneumonia, meningitis and sepsis in children worldwide. Despite available evidence on pneumococcal conjugate vaccine (PCV) impact on pneumonia hospitalizations in children, studies demonstrating PCV impact in morbidity and mortality in middle-income countries are still scarce. Given the disease burden, PCV7 was introduced in Peru in 2009, and then switched to PCV10 in late 2011.

Effectiveness of the 10-Valent Pneumococcal Conjugate Vaccine (PCV-10) in Children in Chile: A Nested Case-Control Study Using Nationwide Pneumonia Morbidity and Mortality Surveillance Data.

Background: The ten-valent pneumococcal conjugate vaccine (PCV10) was introduced into the Chilean National Immunization Program (NIP) in January 2011 with a 3+1 schedule (2, 4, 6 and 12 months) without catch-up vaccination. We evaluated the effectiveness of PCV10 on pneumonia morbidity and mortality among infants during the first two years after vaccine introduction.

Methods: This is a population-based nested case-control study using four merged nationwide case-based electronic health data registries: live birth, vaccination, hospitalization and mortality.

Combining Global Elimination Of Measles And Rubella With Strengthening Of Health Systems In Developing Countries.

Global efforts to eliminate measles and rubella can be combined with other actions to accelerate the strengthening of health systems in developing countries. However, there are several challenges standing in the way of successfully combining measles and rubella vaccination campaigns with health systems strengthening. Those challenges include the following: achieving universal vaccine coverage while integrating the initiative with other primary care strategies and developing the necessary health system resilience to confront emergencies, ensuring epidemiological and laboratory surveillance of vaccine-preventable diseases, developing the human resources needed to effectively manage and implement national strategies, increasing community demand for health services, and obtaining long-term political support.

Country Ownership And Gavi Transition: Comprehensive Approaches To Supporting New Vaccine Introduction.

Since the mid-2000s low- and lower-middle-income countries have been focusing on developing and using evidence for immunization policy making, with an increasing emphasis on cost-effectiveness analysis, program costing, and financial flows-particularly for the introduction of newer, more expensive vaccines. While this is critical to informing decisions, countries still need to increase national immunization investment and explore innovative approaches to augment financing of immunization programs. The need for increased financing is especially strong in countries transitioning from support by Gavi, the Vaccine Alliance.

International Dengue Vaccine Communication and Advocacy: Challenges and Way Forward.

Dengue vaccine introduction will likely occur soon. However, little has been published on international dengue vaccine communication and advocacy. More effort at the international level is required to review, unify and strategically disseminate dengue vaccine knowledge to endemic countries' decision makers and potential donors.

Inaugural conference of the International Association of Immunization Managers (IAIM), Istanbul Turkey, 3-4 March 2015.

For more than 35 years, most national immunization programs have established managerial structures and processes for delivering vaccination services to their populations. These days, immunization managers are facing an increasing number of challenges due to the introduction of new vaccines, shifting demographic patterns, complex networks of service providers, and maintaining the gains achieved with previous vaccination efforts. To confront these challenges, better program performance will require better managerial practices, which incorporates new technologies.

Evidence-based decision-making for vaccine introductions: Overview of the ProVac International Working Group's experience.

Introduction: Pan American Health Organization's (PAHO) ProVac Initiative aims to strengthen countries' technical capacity to make evidence-based immunization policy. With financial support from the Bill and Melinda Gates Foundation, PAHO established the ProVac International Working Group (IWG), a platform created for two years to transfer the ProVac Initiative's tools and methods to support decisions in non-PAHO regions.

Methods: In 2011, WHO Regional Offices and partner agencies established the IWG to transfer the ProVac framework for new vaccine decision support, including tools and trainings to other regions of the world.

ProVac Global Initiative: a vision shaped by ten years of supporting evidence-based policy decisions.
