Coronavirus Disease 2019 Vaccination Booster Effectiveness Based on the 2022 Japanese Dialysis Registry.

ABSTRACT:

Aim

To evaluate the effectiveness of the third, fourth, and fifth booster doses (rolled out in December 2021, June 2022, and October 2022, respectively) of the coronavirus disease 2019 (COVID-19) vaccine in Japanese haemodialysis patients during the Omicron era.

Methods

We analysed the Japanese Society for Dialysis Therapy Renal Data Registry (JRDR) year-end survey data from 2021 to 2022, which included information on the number of vaccinations and the most recent vaccination and infection months. For each month of 2022, the COVID-19 infection and related mortality risks were calculated by vaccination status, followed by logistic regression analyses to estimate adjusted odds ratios (aORs).

Results

Overall, 225 887 patients were analysed, including 13 440 (5.9%), 25 54
