Key lessons learned from the immunization supply chain of Malawi, an African country using EVM2.0.

Objectives: A country's immunization system's effectiveness depends on its supply chain's efficacy. To assess the challenges of maintaining an efficient vaccine supply chain, Malawi conducted its assessment using The EVM2.0 tool (Effective Vaccine Management). Methods: It is a cross-sectional study in which all EVM requirements were assessed between September and October 2021. Data were collected from eighty-two randomly selected sites using the site selection tool of the EVM. Data were entered into the EVM assessment tool 2.0 version 1.12 for analysis. This tool generates performance indicators and criteria scores for assessed sites, compared with a WHO minimum score of 80%. Results: Overall criteria scores across all levels of the immunization supply chain showed a statistically significant mean difference of 5.92 (t = 2.58, P = 0.02). Comparative overall mean criteria scores across different levels of the immunization supply chain showed no statistically significant difference for primary (p = 0.76), sub-national (p = 0.69), and lowest distribution stores (p = 0.12). However, a substantial gap was found in the overall mean scores of the health facility's service point (SP) (t = 4.12, P = 0.001). The overall category scores across all immunization supply chain levels did not show a statistically significant difference. However, among individual category scores, Infrastructure (76 %), Equipment (67 %), Policies and procedures (62 %), Financial (47 %), and Resources (64 %) were found to be below the WHO minimum score. Conclusion: Though the 2021 Malawi EVM assessment findings are promising, they still identified the gaps to be improved to ensure the vaccine availability in the right amount, at the right time, and at the right cost.

COVID-19 provides an opportunity to build a resilient and equitable immunization delivery system.

The COVID-19 pandemic has weakened the health systems in many countries particularly putting at risk efforts on the Immunization Agenda to make vaccination available to everyone, everywhere, by 2030. Immunization Agenda 2030 reconfirms the importance of reducing the absolute number of zero-dose children and increasing the proportion of children who complete their vaccinations on time. Despite the gains in promoting equity in immunization services, many children missed vaccination because of the COVID-19 pandemic that disrupted well planned strategies. The cancellation of outreach services following the COVID-19-motivated lockdown meant many children missed vaccination. The situation was further worsened by vaccination related rumors and fears. The collapse of the Primary Health Care (PHC) service provision during the epidemic may lead to higher under-five mortality similar to the Ebola Virus Disease epidemic in West Africa. The post COVID-19 recovery strategy should include strengthening the service delivery systems to remain resilient when threatened by emergencies. The recovery must therefore focus on rebuilding trust as the foundation for vaccine acceptance and demand which can only be achieved by appropriate community engagement.

An investment case for maternal and neonatal tetanus elimination.

INTRODUCTION: Globally, 13 countries have yet to eliminate maternal and neonatal tetanus. While efforts have improved access to tetanus toxoid containing vaccines (TTCVs) and increased clean delivery practices, reaching elimination targets (<1 case of neonatal tetanus per 1000 live births per district per year) may require significant resources to reach the remaining high risk and hard-to-reach districts. METHODS: We estimated the cost to achieve maternal and neonatal tetanus elimination (MNTE) in three years in the remaining 13 countries: Afghanistan, Angola, Central African Republic, Democratic Republic of the Congo, Guinea, Mali, Nigeria, Pakistan, Papua New Guinea, Somalia, South Sudan, Sudan, and Yemen. Costs were estimated for: (1) vaccination campaigns using standard TTCVs and TT-Uniject™ targeting women of reproductive age in high risk areas, (2) additional vaccinations delivered to pregnant women at antenatal care (ANC) clinics, (3) clean delivery and umbilical cord care promotion, (4) neonatal tetanus surveillance strengthening, and (5) validation activities. We forecasted the averted mortality to assess the cost-effectiveness of achieving MNTE. RESULTS: It will cost an estimated US$197.7 million to realize MNTE over three years. These costs include $161.4 million for vaccination campaigns, $6.1 million for routine vaccination during ANC, $23.3 million for promotion of clean delivery practices, $4 million for surveillance, and $3 million for validation of MNTE. Achieving MNTE will avert approximately 70,000 neonatal deaths over ten years of vaccine protection, resulting in approximately 4.4 million life years gained. It will cost $2,900 per death averted and $45 per life year gained. CONCLUSION: Maternal and neonatal tetanus can be eliminated with significant financial investment, high prioritization, and strong political will. While substantial costs must be incurred to reach hard-to-reach populations, MNTE should be accomplished as a matter of health equity, and will significantly contribute to reaching the United Nations' Sustainable Development Goals.

Progress towards achieving and maintaining maternal and neonatal tetanus elimination in the African region.

Despite the availability of effective tetanus prevention strategies, as of 2016, Maternal and Neonatal Tetanus Elimination (MNTE) has not yet been achieved in 18 countries globally. In this paper, we review the status of MNTE in the World Health Organization African Region (AFR),and provide recommendations for achieving and maintaining MNTE in AFR. As of November 2016, 37 (79%) AFR countries have achieved MNTE, with 10 (21%) countries remaining. DTP3 coverage increased from 52% in 2000 to 76% in 2015. In 2015, coverage with at least 2 doses of tetanus containing vaccine (TT2+) and proportion of newborns protected at birth (PAB) were 69% and 77%, compared with 44% and 62% in 2000, respectively. Since 1999, over 79 million women of reproductive age (WRA) have been vaccinated with TT2+ through supplementary immunization activities (SIAs). Despite the progress, only 54% of births were attended by skilled birth attendants (SBAs), 5 (11%) countries provided the 3 WHO-recommended booster doses to both sexes, and about 5.5 million WRA still need to be reached with SIAs. Coverage disparities still exist between countries that have achieved MNTE and those that have not. In 2015, coverage with DTP3 and PAB were higher in MNTE countries compared with those yet to achieve MNTE: 84% vs. 68% and 86% vs. 69%, respectively. Challenges to achieving MNTE in the remaining AFR countries include weak health systems, competing priorities, insufficient funding, insecurity, and sub-optimal neonatal tetanus (NT) surveillance. To achieve and maintain MNTE in AFR, increasing SBAs and tetanus vaccination coverage, integrating tetanus vaccination with other opportunities (e.g., polio and measles campaigns, mother and child health days), and providing appropriately spaced booster doses are needed. Strengthening NT surveillance and conducting serosurveys would ensure appropriate targeting of MNTE activities and high-quality information for validating the achievement and maintenance of elimination.

Maternal and neonatal tetanus elimination: from protecting women and newborns to protecting all.

A total of 35 of the 59 countries that had not eliminated maternal and neonatal tetanus (MNT) as a public health problem in 1999 have since achieved the MNT-elimination goal. Neonatal tetanus deaths have decreased globally from 200,000 in 2000 to 49,000 in 2013. This is the result of increased immunization coverage with tetanus toxoid-containing vaccines among pregnant women, improved access to skilled birth attendance during delivery, and targeted campaigns with these vaccines for women of reproductive age in high-risk areas. In the process, inequities have been reduced, private-public partnerships fostered, and innovations triggered. However, lack of funding, poor accessibility to some areas, suboptimal surveillance, and a perceived low priority for the disease are among the main obstacles. To ensure MNT elimination is sustained, countries must build and maintain strong routine programs that reach people with vaccination and with clean deliveries. This should also be an opportunity to shift programs into preventing tetanus among all people. Regular assessments, and where needed appropriate action, are key to prevent increases in MNT incidence over time, especially in areas that are at higher risk. The main objective of the paper is to provide a detailed update on the progress toward MNT elimination between 1999 and 2014. It elaborates on the challenges and opportunities, and discusses how MNT elimination can be sustained and to shift the program to protect wider populations against tetanus.
