 This study found that workplace vaccination could lead to better vaccination rates among healthcare workers, HCWs, who are not serologically immune and previously unvaccinated. The study analyzed clinical records of 2,940 HCWs and found that 15.3% were seronegative for measles, especially in the age group under 35 years. The study also confirmed that immunization strategies with pre-vaccination screening are cost-effective compared to vaccination without screening. The study recommends extending pre-vaccination screening to identify real susceptible workers and prevent the transmission of infectious diseases in the hospital setting.
