The parenteral route of drug administration is a vital healthcare procedure used in the administration of medicines using needle and syringe. Despite the importance of this procedure, improper handling of the device has resulted in an unsafe practice among health workers who attend to patients receiving injectable medications. A phased measles vaccination campaign (MVC) was conducted in 2017/2018 with a key objectives of training health workers on injection safety. This paper examines the association between improvement on knowledge of health workers through improved training curriculum and their practice on injection safety. We reviewed information on handling and administration of the measles vaccine from the open data kit (ODK) platform finalised microplans and the training curriculum used during the 2015/2016 and 2017/2018 MVC. We analysed our results using paired t-test analysis, SPSS and M improved the knowledge of health workers. Immunisation programmes will benefit from adopting the training curriculum to meet the specific needs of the health workers. Healthcare personnel vaccinations are important to prevent vaccine-preventable diseases in hospitals. We evaluated the seroprevalence, vaccination rates, and barriers to vaccination among newly employed nurses and doctors. A cross-sectional study was conducted at a university hospital in the Republic of Korea from 2017 to 2020. The immune status for hepatitis B virus (HBV), varicella zoster virus (VZV), and hepatitis A virus (HAV) was tested. HBV, VZV, measles, mumps, and rubella (MMR) vaccinations were mandatory. HAV and tetanus-diphtheria-pertussis (Tdap) vaccinations were also recommended by specialists. A web-based survey on factors affecting vaccination completion was conducted. For the 668 participants, the mean age was 26±2 (±SD) years. Seroprev
