Effects of Simulation on Nursing students' Knowledge and Learning Related to Measles Vaccine and Vaccine Hesitancy: A Mixed Method Study.

Vaccine hesitancy is a persistent, global public health concern that community health nurses are well-positioned to manage. Simulations involving standardized patients are effective experiential learning on managing vaccine hesitancy for other allied health disciplines. A pretest-posttest design, with a mixed-methods, one-group, quasi-experimental approach, was used to examine the effectiveness of a simulation on nursing students' knowledge of measles, mumps, and rubella vaccine hesitancy, as well as their attitudes toward the intervention. The study was completed with 61 participants. After participation in the simulation, pretest/posttest data showed a mean increase in participants' knowledge of the measles, mumps, and rubella vaccine. There was a significant improvement in the test scores from 62.62 ± 14.82 to 69.50 ± 15.75; z = -3, 897 (1-17 days) (p = 0.001). A postintervention questionnaire revealed participants most appreciated the direct interaction with a live person, the opportunity to observe classmates' performance and share feedback, multistage structure, and safety. Drawbacks included stress from being observed by peers, time constraints, and the necessity of sharing the nursing role with a partner during the scenario. Another drawback is the simulation's inability to effectively prepare participants for hesitancy in clinical settings as they needed to assess natural clinical settings. Simulations incorporating vaccine hesitancy education and standardized patients can effectively prepare nursing students for situations related to vaccine hesitancy in community clinical settings.
