The excessive consumption of certain vitamins and minerals could have deleterious consequences on health and development of individuals and populations. Simultaneous micronutrient‐delivery interventions could be challenging in terms of safety as the target populations may overlap, posing a risk of excessive intake of certain micronutrients. The Evidence and Programme Guidance Unit of the Department of Nutrition for Health and Development of the World Health Organization convened a technical consultation on the risk of excessive intake of vitamins and minerals delivered through public health interventions in October 2017. The technical consultation's working groups identified important and emerging technical issues, lessons learned, and research priorities related to (1) planning, implementing, monitoring, and evaluating nutrition programs for the detection and control of the risk of excessive intakes; (2) safety, quality control, and assurance considerations; (3) coordination between public health nutrition interventions and other interventions and sectors; and (4) the legislative framework and policy coherence needed for simultaneous nutrition interventions. This paper provides the background and rationale of the technical consultation, synopsizes the presentations, and provides a summary of the main considerations proposed by the working groups.

In 2020, the World Health Organization launched the Immunization Agenda 2030: A Global Strategy to Leave No One Behind, which prioritizes high equitable immunization coverage at the national level and in all districts. Achieving high and homogenous immunization coverage, which is all the more important within the current context of the COVID-19 pandemic and vaccine rollout, requires the strengthening of existing immunization activities and innovative approach to immunization promotion. This research applied a descriptive case study methodology to document the implementation of strategic multi-level alliances to promote equitable immunization access and demand in Colombia, Guyana, and Sucre, Bolivia. Data collection, carried out between September 2019 and March 2020, included documentary reviews, semi-structured interviews, focus groups, and site visits accompanied by discussions with relevant stakeholders. Case studies provide valuable examples of people-centered, partnership-based, country-owned, and data-guided approaches to promoting equitable immunization coverage, including multi-level partnerships to build technical capacity for the identification and measurement of social inequalities impacting immunization in Colombia; intersectoral and community collaboration for pro-equity emergency response to regional vaccine preventable disease outbreaks in Guyana; and strategic alliances with the education sector and civil society organizations for the introduction of the human papilloma virus (HPV) vaccine in Sucre, Bolivia. Lessons learned highlight avenues for improving the impact of multi-level, equity-focused capacity building, particularly at the local level; optimizing the use of data and resources, partnerships, and community and stakeholder education and empowerment. While impact studies are needed to better understand the quantitative contributions of such strategic alliances, these case studies illustrate their practical significance and reinforce the value of multi-level, intersectoral collaboration for enhancing equitable immunization access and demand. The experiences of Colombia, Guyana, and Sucre, Bolivia provide evidence-based insight to support pro-equity immunization program planning to ensure that no one is left behind and that everyone, everywhere receives the benefits of vaccines, both routine and for COVID-19.
