In what may be the first study of its kind, Johns Hopkins Medicine researchers have documented the reaction of nearly 200 solid organ transplant recipients to their first vaccine inoculation against SARS-CoV-2, the virus that causes COVID-19. The findings, they say, provide evidence that both the Moderna and Pfizer/BioNTech messenger RNA (mRNA) vaccines can be safely given to this immunocompromised population.
To better understand the safety of the SARS-CoV-2 mRNA vaccines for transplant patients, the researchers studied 187 transplant recipients who received an initial dose of either the Moderna or Pfizer/BioNTech vaccines between Dec. 16, 2020and Jan. 16, 2021. The study participants were recruited by invitation through their transplant centers or social media.
