Gilaad Kaplan (University of Calgary) and Sasha Bernatsky (McGill University) on behalf of the STOP COVID-19 in IBD Research Group, showed a robust antibody response was achieved in individuals with IBD after the fourth dose of COVID-19 vaccine, similar in magnitude to that which followed the third dose.
