Study to see if third COVID-19 vaccine dose protects kidney transplant recipients

Johns Hopkins University in Baltimore will enroll up to 200 adults who received a kidney transplant in the past year and had no or low antibody response to two doses of the Moderna or Pfizer COVID-19 vaccine in a study to see if a third dose of the vaccine induces a protective immune response, the National Institutes of Health announced today.

Preliminary results are expected next month. The findings will inform a subsequent larger phase of the trial that includes higher-risk strategies to induce a protective immune response against SARS-CoV-2 in organ transplant recipients who do not respond to a third vaccine dose, NIH said.
