Unlike many undergraduate courses, turning an apprenticeship into an online method is relatively easy. In fact, many apprenticeships take place online and include periodic zoom or Skype sessions between faculty members and students, a specific program for preparing reports and reflections at the end of the apprenticeship, and an uploading system [The apprenticeship stage is also included in the educational programs of Iranian universities as activities that have facilitated performing skills in a real environment.

Therefore, professional knowledge and skills through appropriate training are crucial for public health students who are responsible for all age groups [Since practical training is an essential component of implementing expanded immunization programs in quarantine conditions in Iran, the aim of this study is to determine the effectiveness of online educational videos as an instrument of distance education.
