Method: We conducted a mixed-method cross sectional study, combining qualitative and quantitative approaches on adults who received the second dose of vaccine at Hanoi Medical University from August 2021 to June 2022.With the quantitative part collected by online questionnaires and analyzed using descriptive statistics by the Stata 15.0 software. For the qualitative part, we used the content analysis strategy of in-depth interviews. Results: 696 people participated in the study and the majority of those experienced post-vaccination symptoms (88.5%), followed by tiredness, fever and the increased pain at the injection site. Most respondents felt satisfied with the vaccination process (98.4%). The in-depth interviews showed 5 feelings during the injection, including anxiety, suspense, fear, non-anxiety, and satisfaction. Negative experiences were mainly related to post-injection side effects and most common at the first dose of vaccine. Common related factors included: individual factors; family and friends; vaccines; injection environment; reference sources and other social factors. The vaccine factor was reported to have the most impact on vaccination experience. Recommendations: Enhance professionalism according to the vaccination organization process as well as improve the efficiency of pre-, during and post-injection consultations of medical vaccination facilities in the locality. At the same time, regularly update and ensure the quality of information sources, especially vaccination information on the electronic system for easy access by injectors and agencies and organizations.
