Introduction: FGDs (focus group discussions) are commonly conducted in research to have a deeper understanding of a phenomenon and for various others reasons. Also in respect to vaccination among children and adolescents, fgds have been conducted for studying coverage, hesitancy, refusal, knowledge, attitude and other variables. Methods: Studies conducted after the year 2000 till 2020 have been reviewed using search results from pubmed, DOAJ and Google Scholar. Studies that meet eligibility criteria and quality assessment (CASP) were reviewed using PRISMA guidelines. Results: all the studies included were of high quality. 14 studies met the eligibility criteria and quality assessment criteria according to CASP checklist with score ≥7. This included 11 qualitative and 3 mixed method studies using FGDs as a part of their study. The studied aspects were parents and caregivers knowledge, experience, perceptions, attitude, health system barriers and decision making process and factors affecting it. Conclusion: there is high variability in the number of participants, sessions conducted and total sample size that ranged from 3-13, 1 and 12-98 respectively depending upon data saturation which seems to have been attained early in these cases. The knowledge and attitude regarding vaccination is seen to favourable except for few vaccines like MMR and hepatitis. Some health system barriers have also been identified but are limited to underdeveloped countries. Overall vaccination coverage and the related factors and the concerns about vaccination decision are determined by parent’s education status and information provide by HCPs.
