1) Non-biological factors like social, economic, and political determinants significantly impact the success of immunization programs. These include factors like parental education, access to healthcare, gender inequity, and governance. 2) When a new vaccine for tuberculosis becomes available, factors like public acceptance, financing, and sustainability will determine its adoption in immunization programs. 3) A study on factors influencing the introduction of new vaccines in African countries supported by GAVI found that better governance indicators, like political stability and control of corruption, were a stronger predictor of adoption than financial healthcare indicators. Addressing social and behavioral determinants is important for effective vaccine introduction and implementation.
