Barriers and activities to implementing or expanding influenza vaccination programs in low- and middle-income countries: A global survey.

INTRODUCTION: Despite considerable global burden of influenza, few low- and middle-income countries (LMICs) have national influenza vaccination programs. This report provides a systematic assessment of barriers to and activities that support initiating or expanding influenza vaccination programs from the perspective of in-country public health officials. METHODS: Public health officials in LMICs were sent a web-based survey to provide information on barriers and activities to initiating, expanding, or maintaining national influenza vaccination programs. The survey primarily included Likert-scale questions asking respondents to rank barriers and activities in five categories. RESULTS: Of 109 eligible countries, 62% participated. Barriers to influenza vaccination programs included lack of data on cost-effectiveness of influenza vaccination programs (87%) and on influenza disease burden (84%), competing health priorities (80%), lack of public perceived risk from influenza (79%), need for better risk communication tools (77%), lack of financial support for influenza vaccine programs (75%), a requirement to use only WHO-prequalified vaccines (62%), and young children require two vaccine doses (60%). Activities for advancing influenza vaccination programs included educating healthcare workers (97%) and decision-makers (91%) on the benefits of influenza vaccination, better estimates of influenza disease burden (91%) and cost of influenza vaccination programs (89%), simplifying vaccine introduction by focusing on selected high-risk groups (82%), developing tools to prioritize target populations (80%), improving availability of influenza diagnostic testing (79%), and developing collaborations with neighboring countries for vaccine procurement (74%) and regulatory approval (73%). Responses varied by country region and income status. CONCLUSIONS: Local governments and key international stakeholders can use the results of this survey to improve influenza vaccination programs in LMICs, which is a critical component of global pandemic preparedness for influenza and other pathogens such as coronaviruses. Additionally, strategies to improve global influenza vaccination coverage should be tailored to country income level and geographic location.

Shaping meeting to explore the value of a coordinated work plan for epidemic and pandemic influenza vaccine preparedness.

In March 2019, a group of global health leaders with expertise in influenza, vaccinology and pandemic preparedness was convened for a meeting titled "Shaping Meeting to explore the value of a coordinated work plan for epidemic and pandemic influenza vaccine preparedness." Influenza epidemics occur annually in every country in the world, resulting in significant global burden of illness and deaths. While every country is effected, most deaths and severe disease occur in low- and lower middle-income countries (LIC and LMIC). Influenza immunization programs that limit the burden of disease, deaths, and reduce economic impact are a fundamental public health intervention for seasonal epidemics. In addition, they provide the experience, systems and infrastructure for the timely and efficient use of vaccines and other medical countermeasures critical for effective pandemic responses. Pandemic influenza response activities, including vaccination efforts, will be most effective if used and practiced regularly. Consequently, countries with seasonal influenza prevention and control programs should be better prepared for, and have more effective pandemic responses than countries without such programs. A decade after the 2009 pandemic, despite ongoing prevention efforts, most LICs and LMICs still lack access to robust seasonal influenza immunization programs. Given this current state, meeting participants concluded that there is critical need to advance the expansion and strengthening of seasonal influenza immunization programs in LICs and LMICs not only to reduce the economic and public health effects of annual influenza epidemics, but also to increase preparedness to mitigate the threat of future pandemics and improve global heath security. Many government and private sectors, in a whole of government approach, need to be working together to support and advance countries' epidemic and pandemic influenza capacities preparedness objectives. Accomplishment of these objectives can be achieved with a coordinated work plan developed and guided by an alliance of international stakeholders, to include, among others, government, and nongovernment organization representation, civil society representatives, vaccine manufacturers, international organizations, and health security and influenza experts.

Influenza vaccination policies for health workers in low-income and middle-income countries: A cross-sectional survey, January-March 2020.

INTRODUCTION: The World Health Organization (WHO) recommends vaccination of health workers against influenza, but uptake in low-resource settings remains low. To complement routine global data collection efforts we conducted a detailed survey on influenza vaccination policies for health workers in low-income and middle-income countries (LMICs) in early 2020. METHODS: Health worker vaccination policy data were collected via a web-based survey tool sent to Expanded Programme on Immunization managers or equivalent managers of all eligible countries. High-income countries and countries with active civil war were excluded from the participation. The survey was sent by email to 109 LMICs in all WHO Regions to invite participation. Data were analyzed by World Bank income category and WHO Region. Statistical methods were applied to assess mean vaccination rates across countries. RESULTS: Sixty-eight (62%) out of 109 invited LMICs were studied. Thirty-five (51.5%) reported to have a policy for influenza vaccination of health workers. Vaccinations were voluntary in 23 countries (66%), mandatory in 4 (11%), while in 8 countries (23%) mixed vaccination policies existed. A mechanism to estimate vaccine uptake existed in 26 countries (74%). Low-income and African Region countries were less likely to have influenza vaccination policies for health workers (p-values < 0.001 and 0.009, respectively). The most common reason for not having a vaccination policy for health workers was influenza not being a priority (48.5%). CONCLUSIONS: Despite policies being in place in more than half LMICs studied, gaps remain in translating vaccination policies to action, particularly in low-income and African Region countries. To optimize the operationalization of policies, further research is needed within countries, to enable evidence-based introduction decisions, categorization of health workers for vaccination, identification of factors impacting effective service delivery, strengthening monitoring and estimation of vaccination uptake rates and ensure sustainability of funding.
