Introduction: Nigeria adopted the expanded program on immunization (EPI) in 1978, which aimed at offering children under 2 years old routine immunization (RI). Early accomplishments with the program resulted in a decrease in childhood mortality. As of 2018, Nigeria accounted for about 4.3 million out of over 13 million unvaccinated children globally. Therefore, this study revealed the challenges and efforts associated with RI program in Nigeria and the way forward.
Methods: In this perspective article, I conducted searches and extracted relevant information from publicly available sources such as Google Scholar, Pubmed, and grey literature. I employed RI, challenges, efforts, and Nigeria as the keywords.
Results: The 2021 Multiple Indicator Cluster Survey/National Immunization Coverage Survey reports revealed weaknesses in the program, with a national average coverage of 36%. The primary barrier to EPI across various zones is the challenge of reaching marginalized areas that were cut off from vaccination services due to operational and sociocultural issues. Some of the obstacles, such as restricted access to medical facilities, weak cold chain systems, and COVID-19 containment strategies had a great impact on the RI program. To scale up the RI program, the Nigerian government, through the National Primary Health Care Development Agency (NPHCDA), collaborated with the World Health Organization (WHO) and Gavi, the Vaccine Alliance, to optimize the "Big Catch-up campaign" and increase immunization coverage nationwide. By 2028, 80% of the projected zero-dose populace is expected to be covered, reaching these eligible children with life-saving vaccines.
Conclusion: Nigeria still has a long way to go in making significant progress in the RI program. To further strengthen the immunization coverage, the country needs to maintain data on their achievements, as this will help identify gaps that need to be addressed in the immunization program.

Introduction: Home-based records (HBRs) are widely used for recording health information including child immunisations. We studied levels and inequalities in HBR ownership in low-income and middle-income countries (LMICs) using data from national surveys conducted since 2010.
Methods: We used data from national household surveys (Demographic and Health Surveys (DHS) and Multiple Indicator Cluster Surveys (MICS)) from 82 LMICs.

Objective: In Japan, the current coverage rate of human papillomavirus (HPV) vaccination is only 30%, and the rate of biennial cervical screening is 40%. The Japanese Government has attempted to increase the coverage of HPV vaccination and cervical screening. We analyzed the cost-effectiveness of the 9-valent HPV vaccine and cervical screening in Japan.

Background: Despite high COVID-19 vaccine coverage in Canada, vaccine acceptance and preferred delivery among newcomers, racialized persons, and those who primarily speak minority languages are not well understood. This national study explores COVID-19 vaccine acceptance, access to vaccines, and delivery preferences among ethnoculturally diverse population groups.
Methods: We conducted two national cross-sectional surveys during the pandemic (Dec 2020 and Oct-Nov 2021).
