essential, cost-effective public health measure to reduce preventable, premature, child mortality and childhood morbidity The pentavalent vaccination contributes to lowering the spread of vaccine-preventable diseases Health care workers’ knowledge and practices with the use of the pentavalent vaccination are influential factors in preventing pentavalent vaccine failures One of the main reasons parents accept immunization for their children is that it is recommended by health care providers This fact underlines the important role of health care providers in increasing parents’ confidence in immunization by dealing with their concerns, answering their questions and convincingly resolving their doubts The aim of this study is to assess the knowledge and practice of providing pentavalent vaccines and their related factors among health care workers This was a cross-sectional analytical study, using the mixed-method approach that combines qualitative and quantitative methods This study was conducted in nine district hospitals and 33 health centers in Vientiane Capital In total, 184 health care workers were involved in the study and 12 HCWs were involved in the in-depth interviews The quantitative data was entered using the EpiData programme and analyzed using the Stata 14.1 programme Descriptive and inferential statistics were applied to determine the factors associated with the knowledge and practice of pentavalent vaccines A thematic analysis was applied for the qualitative data From among the 184 respondents, the results showed that under two thirds of them (63.3%) had a poor knowledge of the pentavalent vaccine and that slightly less than two thirds of health care workers (65.7%) had a good practice of the pentavalent vaccine The findings from the in-depth interviews which were also supported by the quantitative method showed that the HCWs in this study had a poor knowledge of the side effects of pentavalent vaccines as they had incorrect answers about the severe side effects of pentavalent vaccines such as analphylactic shock and the loss of appetite after receiving the pentavalent vaccine
