Mothers in Nigeria were between 2-4 times more likely to have fully immunized children if they attended 1-3 antenatal care (ANC) visits, between 2.5-8 times more likely if they attended 4-7 ANC visits, and between nearly 3-14 times more likely if they attended at least 8 ANC visits compared to those who had no ANC.
Similar findings have been seen in many LMICs, including Senegal, Bangladesh, Indonesia, India, Zimbabwe, and Southwest Ethiopia.
Mothers who had skilled birth attendance and post-natal care were approximately 6 times were likely to have fully immunized children.
The use of antenatal care (ANC) services among pregnant adolescents in low- and middle-income countries, including tetanus toxoid vaccination, was lowest among women who lived in rural areas, had completed less education, and who were of poorer wealth quintiles.
A systematic review of 8 African countries that had wild polio virus transmission and significant polio eradication activities found evidence that the huge investments made in polio have strengthened capacity in almost all aspects of the overall immunization systems, especially in the areas of microplanning, service delivery, capacity-building (especially supportive supervision and on-the-job training), and program management. This led to substantial increases in coverage of other routine vaccinations – BCG, DPT, measles – in all 8 countries over a 25-year period (1989-2014), including a more than a 3-fold increase in DPT3 coverage in 2 countries and a more than a 2-fold increase in 3 other countries.
According to a systematic review and meta-analysis, children who are rural-urban migrants in China, India and Nigeria were less likely to be fully-immunized by the age of one year than non-migrant urban residents and the general population. These inequities in vaccination rates — often concealed in national averages — call for special efforts to improve immunization rates in this rapidly growing sub-population to reduce both health inequities and the risk of infectious disease outbreaks in the wider society.
In a Southwest state of Nigeria, children in the poorest category (quintile) of households were 14 times more likely to be partially immunized or not immunized, and those in the next poorest category were eight times more likely to be partially immunized or not immunized than children in the wealthiest group, after adjusting for factors such as education, religion, and ethnicity.
Children born to mothers in Southwest Nigeria who had no formal education were four times more likely to be unvaccinated or partially vaccinated than those born to mothers who completed primary school and were six times more likely to be partially vaccinated or unvaccinated than children whose mothers completed a post-secondary education.
Fear of Ebola during the 2014-2016 epidemic in 3 West African countries had a major impact on the health sector in neighboring Nigeria, where hospitals some hospitals also turned away febrile patients to prevent being associated with Ebola while staff in other hospitals abandoned their posts.
The expertise and assets gained through efforts to eradicate polio at least partially explain the improvement between 2013 and 2015 in vaccination coverage of DPT3 in six out of ten “focus” countries of the Polio Eradication Endgame strategic plan. This includes substantial increases in vaccination rates in India, Nigeria, and Ethiopia, which, combined, reduced the number of children not fully vaccinated with DPT by 2 million in 2 years.
Maternal education benefits immunization rates of all community members, not only mothers’ own children. In Nigeria, children’s odds of being fully immunized improved by 1.06 times for every additional year of education the mothers received. Children’s odds of being fully immunized increased by 1.2 times for each additional year of maternal education in the community.
