The Impact

AbstractIntroductionThe world is not on track to achieve the goals for immunization coverage and equity described by the World Health Organization’s Global Vaccine Action Plan. In India, only 62% of children had received a full course of basic vaccines in 2016. We evaluated the Intensified Mission Indradhanush (IMI), a campaign-style intervention to increase routine immunization coverage and equity in India, implemented in 2017-2018.MethodsWe conducted a comparative interrupted time-series analysis using monthly district-level data on vaccine doses delivered, comparing districts participating and not participating in IMI. We estimated the impact of IMI on coverage and under-coverage (defined as the proportion of children who were unvaccinated) during the four-month implementation period and in subsequent months.FindingsDuring implementation, IMI increased delivery of thirteen infant vaccines by between 1.6% (95% CI: −6.4, 10.2%) and 13.8% (3.0%, 25.7%). We did not find evidence of a sustained effect during the 8 months after implementation ended. Over the 12 months from the beginning of implementation, IMI reduced under-coverage of childhood vaccination by between 3.9% (−6.9%, 13.7%) and 35.7% (−7.5%, 77.4%). The largest estimated effects were for the first doses of vaccines against diptheria-tetanus-pertussis and polio.InterpretationIMI had a substantial impact on infant immunization delivery during implementation, but this effect waned after implementation ended. Our findings suggest that campaign-style interventions can increase routine infant immunization coverage and reach formerly unreached children in the shorter term, but other approaches may be needed for sustained coverage improvements.FundingBill & Melinda Gates Foundation.

Measles Incidence

Background: According to the World Health Organization (WHO), Indonesia is one of the ten countries with the most significant number of measles cases in the world. Immunization coverage in Trenggalek Regency has reached the target of prevention of measles in the elimination stage, namely measles immunization coverage> 95%, the incidence of measles persists and increases in the last three years, from 2013 to 2015. Purpose: This study aimed to evaluate the trends between measles immunization status and the provision of vitamin A with the incidence of measles in Trenggalek Regency. Methods: This type of research is an observational study with a cross-sectional study design. The sample population is consist of 14 sub-districts in Trenggalek Regency. Data was taken from the health profile of Trenggalek Regency in 2013, 2014, and 2015. In this study, data processing were analysed by Health Mapper application version 4.3.0.0 with product version 4.03 to determine data descriptively. Results: Distribution of measles incidence with immunization coverage in Trenggalek Regency in 2013, 2014, and 2015 showed that measles incidence tended to increase followed with the decreasing number of measles immunization coverage each year. Ironically, the distribution of measles incidence with vitamin A administration in 2013, 2014, and 2015 showed the incidence of measles had increased because of the inconsistent amount of vitamin A administration. Conclusion: Measles incidence tends to occur in low immunization coverage areas and has decreased from the previous year. Giving vitamin A does not prevent the occurrence of measles, but serves to reduce compilation.

Background Despite efforts to improve childhood immunization coverage in Nigeria, coverage has remained below the national acceptable level. In December 2019, we conducted an assessment of Missed Opportunities for Vaccination (MOV) in Ondo State, in Southwest Nigeria. The objectives were to determine the magnitude of, explore the reasons for, as well as possible solutions for reducing MOV in the State. Methods This was a cross-sectional study using a mixed-methods approach. We purposively selected 66 health facilities in three local government authorities, with a non-probabilistic sampling of caregivers of children 0–23 months for exit interviews, and health workers for knowledge, attitudes, and practices (KAP) surveys. Data collection was complemented with focus group discussions and in-depth interviews with caregivers and health workers. The proportion of MOV among children with documented vaccination histories were determined and thematic analysis of the qualitative data was carried out. Results 984 caregivers with children aged 0–23 months were interviewed, of which 869 were eligible for inclusion in our analysis. The prevalence of MOV was 32.8%. MOV occurred among 90.8% of children during non-vaccination visits, and 7.3% during vaccination visits. Vaccine doses recommended later in the immunization series were given in a less timely manner. Among 41.0% of health workers, they reported their vaccination knowledge was insufficient. Additionally, 57.5% were concerned about and feared adverse events following immunization. Caregivers were found to have a low awareness about vaccination, and issues related to the organization of the health system were found to contribute towards MOV. Conclusions One in three children experienced a MOV during a health service encounter. Potential interventions to reduce MOV include training of health workers about immunization policies and practices, improving caregivers’ engagement and screening of vaccination documentation by health workers during every health service encounter.

Coverage Quality

One important strategy to increase vaccination coverage is to minimize missed opportunities for vaccination. Missed opportunities for simultaneous vaccination (MOSV) occur when a child receives one or more vaccines but not all those for which they are eligible at a given visit. Household surveys that record children’s vaccination dates can be used to quantify occurrence of MOSVs and their impact on achievable vaccination coverage. We recently automated some MOSV analyses in the World Health Organization’s freely available software: Vaccination Coverage Quality Indicators (VCQI) making it straightforward to study MOSVs for any Demographic & Health Survey (DHS), Multi-Indicator Cluster Survey (MICS), or Expanded Programme on Immunization (EPI) survey. This paper uses VCQI to analyze MOSVs for basic vaccine doses among children aged 12–23 months in four rounds of DHS in Colombia (1995, 2000, 2005, and 2010) and five rounds of DHS in Nigeria (1999, 2003, 2008, 2013, and 2018). Outcomes include percent of vaccination visits MOSVs occurred, percent of children who experienced MOSVs, percent of MOSVs that remained uncorrected (that is, the missed vaccine had still not been received at the time of the survey), and the distribution of time-to-correction for children who received the MOSV dose at a later visit.

The Impact

There is a lack of comprehensive and systematic data and evidence regarding the effectiveness of mandatory and incentive-based vaccination schemes. The results of such programs in some countries have not been adequately studied. A number of countries have recently introduced tightening vaccination measures, and it is important to analyze and assess the results of these programs. The unprecedented situation due to the COVID-19 pandemic and mass vaccination made the topic of the effectiveness of vaccination policies and mandates even more relevant. The aim of the study is to assess childhood vaccination programs implemented in selected countries. The study focuses on initiatives implemented in the European Region of the World Health Organization (WHO). A total of 466 full-text articles were assessed for eligibility, and 26 articles on seven countries were included in the synthesis. Additionally, we obtained and performed an analysis of data on the impact of COVID-19 on vaccine coverage and incidence of vaccine-preventable diseases, and the implementation of vaccine mandates in the selected countries. The evidence collected and analyzed in this review allowed us to conclude that the introduction of children routine vaccination mandates increases vaccine coverage and reduces the incidence of vaccine-preventable diseases when compared to the situation before the introduction of the mandates.

The Impact

Abstract Background Inability to track children’s vaccination history coupled with parents’ lack of awareness of vaccination due dates compounds the problem of low immunization coverage and timeliness in developing countries. Traditional Reminder/Recall (RR) interventions such as paper-based immunization cards or mHealth based platforms do not yield optimal results in resource-constrained settings. There is thus a need for a low-cost intervention that can simultaneously stimulate demand and track immunization history to help reduce drop-outs and improve immunization coverage and timeliness. The objective of this study is to evaluate the impact of low-cost vaccine reminder and tracker bracelets for improving routine childhood immunization coverage and timeliness in Pakistani children under 2 years of age. Methods The study is an individually randomized, three-arm parallel Randomized Controlled Trial with two intervention groups and one control group. Infants in the two intervention groups will be given two different types of silicone bracelets at the time of recruitment, while infants in the control group will not receive any intervention. The two types of bracelets consist of symbols and/or numbers to denote the EPI vaccination schedule and each time the child will come for vaccination, the study staff will perforate a hole in the appropriate symbol to denote vaccine administration. Therefore, by looking at the bracelet, caregivers will be able to see how many vaccines have been received. Our primary outcome measure is the increase in coverage and timeliness of Pentavalent-3/PCV-3/Polio-3 and Measles-1 vaccine in the intervention versus control groups. A total of 1446 participants will be recruited from 4 Expanded Program on Immunization (EPI) centers in Landhi Town, Karachi. Each enrolled child will be followed up till the Measles-1 vaccine is administered, or till eleven months have elapsed since enrolment. Discussion Participant recruitment commenced on July 19, 2017, and was completed on October 10, 2017. Proposed duration of the study is 18 months and expected end date is December 1, 2018. This study constitutes one of the first attempts to rigorously evaluate an innovative, low-cost vaccine reminder bracelet. Trial registration ClinicalTrials.gov NCT03310762. Retrospectively Registered on October 16, 2017.

According to the World Health Organization, researchers estimate that the spread of vaccines has allowed worldwide life expectancy to increase by 30 years in the past two centuries. Despite these advances, there are major challenges to be overcome to expand immunization coverage. Currently, the Unified Health System (SUS) offers a total of 19 vaccines that protect against more than 40 diseases free of charge. Therefore, the objective of the study was to study and analyze the current state of Brazilian vaccination in relation to infectious diseases eradicated in the country. For the development of the work, data from the Ministry of Health, published scientific articles in the Google academic, SCIELO and PubMed databases, epidemiological bulletins, as well as relevant studies and reports published on websites and internet portals through the descriptors, vaccination in Brazil, vaccination delay in Brazil, vaccines available in the single system were used (SUS). Through this work, it is concluded that the lack of information in a set of other factors generates the non-vaccination of the population, resulting in the return of previously eradicated diseases.
