Background: While effective preventive measures reduce hospital-acquired infections (HAIs) and the spread of multi-drug resistant organisms (MDROs), studies on the impact of the COVID-19 pandemic and its associated preventive measures remain inconclusive.
Objective: To assess the impact of COVID-19 on HAIs and MDROs and to compare it with the effect of seasonal influenza.
Methods: A retrospective cohort study analyzed prospectively collected data from a tertiary hospital in Haifa, northern Israel, from 2016 to 2021.
Background: Previous studies showed that the fourth SARS-CoV-2 vaccine dose has a protective effect against infection, as well as against severe disease and death. This study aimed to examine whether knowledge of a high-level antibody after the third dose may reduce compliance to the fourth booster dose among healthcare workers (HCWs).
Methods: We conducted a prospective cohort study among HCWs vaccinated with the first three doses at Rambam Healthcare Campus, a tertiary hospital in northern Israel.
Introduction: The fourth SARS-CoV-2 vaccine dose was found to protect against infection and more importantly against severe disease and death. It was also shown that the risk of symptomatic or severe disease was related to the antibody levels after vaccination or infection, with lower protection against the BA.4 BA.

This prospective cohort study of HCW tested for anti-spike antibodies (LIAISON SARS-CoV-2 S1/S2 IgG assay) at 1, 3, 6, 9, and 12 months after receiving the second BNT162b2 vaccine dose (tests 1, 2, 3, 4, and 5, respectively). A third (booster) vaccination dose was introduced before test 4.
