Recently, two Phase 2B tuberculosis vaccine trials reported positive efficacy results in adolescents and adults. However, experience in vaccinating these age groups is limited. We identified potential implementation strategies for the M72/AS01E vaccination and BCG-revaccination-like candidates and explored their acceptability and feasibility. We conducted in-depth semi-structured interviews among key decision makers to identify implementation strategies and target groups in South Africa, India, and China. Thematic and deductive analysis using a coding framework were used to identify themes across and within settings. In all three countries there was interest in novel TB vaccines, with school-attending adolescents named as a likely target group. In China and India, older people were also identified as a target group. Routine vaccination was preferred in all countries due to stigma and logistical issues with targeted mass campaigns. Perceived benefits for implementation of M72/AS01E were the likely efficacy in individuals with Mycobacterium tuberculosis (Mtb) infection and efficacy for people living with HIV. Perceived challenges for M72/AS01E included the infrastructure and the two-dose regimen required. Stakeholders valued the familiarity of BCG but were concerned about the adverse effects in people living with HIV, a particular concern in South Africa. Implementation challenges and opportunities were identified in all three countries. Our study provides crucial information for implementing novel TB vaccines in specific target groups and on country specific acceptability and feasibility. Key groups for vaccine implementation in these settings were identified, and should be included in clinical trials and implementation planning.

Background:The isolation from mainstream development activities, together with poverty and inaccessibility to health facilities made the tribal communities specifically vulnerable to various health problems.Objectives:This study aimed to compare the utilization of antenatal care, immunization, and supplementary nutrition services by tribal and nontribal mothers and its correlates in the selected districts.Materials and Methods:The study was a comparative cross-sectional study. The study population comprised tribal and nontribal mothers utilizing antenatal care, immunization, and supplementary nutrition services. A multi-stage cluster sampling strategy was employed for the study. The Chi-square test was used to assess the association between antenatal care services utilization, utilization of immunization services, supplementary nutrition services utilization and sociodemographic variables, and other service characteristics.Results:Effective utilization of antenatal care services was not seen in 5.6% of tribal mothers. The incidence of low-birth weight (≤2500) was significantly more among tribal mothers (31%) when compared to nontribal mothers (15%). The proportion of tribal children receiving complete immunization without delay was 74%, and among nontribal children, it was 78%. Effective immunization coverage was significantly lower among children of tribal mothers with education below high school level. Receipt of take-home ration was reported by nearly 90% of tribal and nontribal mothers. 90% of tribal mothers felt that quality of take-home ration that they received was of good quality.Conclusions:The comparison of health-care utilization restricted to the domains of antenatal care, immunization services, and supplementary nutrition suggests that the tribal mothers and children had a relatively comparable utilization pattern in most of the indicators measured.
